About Web Design – woobicha

Usability and the utility, not the visual design, determine the success or failure of a web-site. Since the visitor of the page is the only person who clicks the mouse and therefore decides everything, user-centric design has become a standard approach for successful and profit-oriented web design. After all, if users can’t use a feature, it might as well not exist.

Effective Web Design

In order to use the principles properly we first need to understand how users interact with web-sites, how they think and what are the basic patterns of users’ behavior.

How do users think?

Basically, users’ habits on the Web aren’t that different from customers’ habits in a store. Visitors glance at each new page, scan some of the text, and click on the first link that catches their interest or vaguely resembles the thing they’re looking for. In fact, there are large parts of the page they don’t even look at.
Most users search for something interesting (or useful) and clickable; as soon as some promising candidates are found, users click. If the new page doesn’t meet users’ expectations, the Back button is clicked and the search process is continued.

Users appreciate quality and credibility. If a page provides users with high-quality content, they are willing to compromise the content with advertisements and the design of the site. This is the reason why not-that-well-designed web-sites with high-quality content gain a lot of traffic over years. Content is more important than the design which supports it.
Users don’t read, they scan. Analyzing a web-page, users search for some fixed points or anchors which would guide them through the content of the page.

Web users are impatient and insist on instant gratification. Very simple principle: If a web-site isn’t able to meet users’ expectations, then designer failed to get his job done properly and the company loses money. The higher is the cognitive load and the less intuitive is the navigation, the more willing are users to leave the web-site and search for alternatives.

Users don’t make optimal choices. Users don’t search for the quickest way to find the information they’re looking for. Neither do they scan web-page in a linear fashion, going sequentially from one site section to another one. Instead users satisfice; they choose the first reasonable option. As soon as they find a link that seems like it might lead to the goal, there is a very good chance that it will be immediately clicked. Optimizing is hard, and it takes a long time. Satisficing is more efficient.

Users follow their intuition. In most cases users muddle through instead of reading the information a designer has provided. According to Steve Krug, the basic reason for that is that users don’t care. “If we find something that works, we stick to it. It doesn’t matter to us if we understand how things work, as long as we can use them. If your audience is going to act like you’re designing billboard, then design great billboards.”

Users want to have control. Users want to be able to control their browser and rely on the consistent data presentation throughout the site. E.g. they don’t want new windows popping up unexpectedly and they want to be able to get back with a “Back”-button to the site they’ve been before: therefore it’s a good practice to never open links in new browser windows.

Effective Web Design

1. Don’t make users think

According to Krug’s first law of usability, the web-page should be obvious and self-explanatory. When you’re creating a site, your job is to get rid of the question marks — the decisions users need to make consciously, considering pros, cons and alternatives.
If the navigation and site architecture aren’t intuitive, the number of question marks grows and makes it harder for users to comprehend how the system works and how to get from point A to point B. A clear structure, moderate visual clues and easily recognizable links can help users to find their path to their aim.

2. Don’t squander users’ patience

In every project when you are going to offer your visitors some service or tool, try to keep your user requirements minimal. The less action is required from users to test a service, the more likely a random visitor is to actually try it out. First-time visitors are willing to play with the service, not filling long web forms for an account they might never use in the future. Let users explore the site and discover your services without forcing them into sharing private data. It’s not reasonable to force users to enter an email address to test the feature.

3. Manage to focus users’ attention

As web-sites provide both static and dynamic content, some aspects of the user interface attract attention more than others do. Obviously, images are more eye-catching than the text — just as the sentences marked as bold are more attractive than plain text.
The human eye is a highly non-linear device, and web-users can instantly recognize edges, patterns and motions. This is why video-based advertisements are extremely annoying and distracting, but from the marketing perspective they perfectly do the job of capturing users’ attention.

4. Strive for feature exposure

Modern web designs are usually criticized due to their approach of guiding users with visually appealing 1-2-3-done-steps, large buttons with visual effects etc. But from the design perspective these elements actually aren’t a bad thing. On the contrary, such guidelines are extremely effective as they lead the visitors through the site content in a very simple and user-friendly way.
Letting the user see clearly what functions are available is a fundamental principle of successful user interface design. It doesn’t really matter how this is achieved. What matters is that the content is well-understood and visitors feel comfortable with the way they interact with the system.

5. Make use of effective writing

As the Web is different from print, it’s necessary to adjust the writing style to users’ preferences and browsing habits. Promotional writing won’t be read. Long text blocks without images and keywords marked in bold or italics will be skipped. Exaggerated language will be ignored.

Talk business. Avoid cute or clever names, marketing-induced names, company-specific names, and unfamiliar technical names. For instance, if you describe a service and want users to create an account, “sign up” is better than “start now!” which is again better than “explore our services”.

An optimal solution for effective writing is to:

• use short and concise phrases (come to the point as quickly as possible),
• use scannable layout (categorize the content, use multiple heading levels, use visual elements and bulleted lists which break the flow of uniform text blocks),
• use plain and objective language (a promotion doesn’t need to sound like advertisement; give your users some reasonable and objective reason why they should use your service or stay on your web-site)

6. Strive for simplicity

The “keep it simple”-principle (KIS) should be the primary goal of site design. Users are rarely on a site to enjoy the design; furthermore, in most cases they are looking for the information despite the design. Strive for simplicity instead of complexity.
From the visitors’ point of view, the best site design is a pure text, without any advertisements or further content blocks matching exactly the query visitors used or the content they’ve been looking for. This is one of the reasons why a user-friendly print-version of web pages is essential for good user experience.

7. Don’t be afraid of the white space

Actually it’s really hard to overestimate the importance of white space. Not only does it help to reduce the cognitive load for the visitors, but it makes it possible to perceive the information presented on the screen. When a new visitor approaches a design layout, the first thing he/she tries to do is to scan the page and divide the content area into digestible pieces of information.
Complex structures are harder to read, scan, analyze and work with. If you have the choice between separating two design segments by a visible line or by some whitespace, it’s usually better to use the whitespace solution. Hierarchical structures reduce complexity (Simon’s Law): the better you manage to provide users with a sense of visual hierarchy, the easier your content will be to perceive.

8. Communicate effectively with a “visible language”

In his papers on effective visual communication, Aaron Marcus states three fundamental principles involved in the use of the so-called “visible language” — the content users see on a screen.

Organize: provide the user with a clear and consistent conceptual structure. Consistency, screen layout, relationships and navigability are important concepts of organization. The same conventions and rules should be applied to all elements.
Economize: do the most with the least amount of cues and visual elements. Four major points to be considered: simplicity, clarity, distinctiveness, and emphasis. Simplicity includes only the elements that are most important for communication. Clarity: all components should be designed so their meaning is not ambiguous. Distinctiveness: the important properties of the necessary elements should be distinguishable. Emphasis: the most important elements should be easily perceived.
Communicate: match the presentation to the capabilities of the user. The user interface must keep in balance legibility, readability, typography, symbolism, multiple views, and color or texture in order to communicate successfully. Use max. 3 typefaces in a maximum of 3 point sizes — a maximum of 18 words or 50-80 characters per line of text.

9. Test early, test often

This so-called TETO-principle should be applied to every web design project as usability tests often provide crucial insights into significant problems and issues related to a given layout.
Test not too late, not too little and not for the wrong reasons. In the latter case it’s necessary to understand that most design decisions are local; that means that you can’t universally answer whether some layout is better than the other one as you need to analyze it from a very specific point of view (considering requirements, stakeholders, budget etc.).
Some important points to keep in mind:
-according to Steve Krug, testing one user is 100% better than testing none and testing one user early in the project is better than testing 50 near the end. Accoring to Boehm’s first law, errors are most frequent during requirements and design activities and are the more expensive the later they are removed.
-testing is an iterative process. That means that you design something, test it, fix it and then test it again. There might be problems which haven’t been found during the first round as users were practically blocked by other problems.
-usability tests always produce useful results. Either you’ll be pointed to the problems you have or you’ll be pointed to the absence of major design flaws which is in both cases a useful insight for your project.
-according to Weinberg’s law, a developer is unsuited to test his or her code. This holds for designers as well. After you’ve worked on a site for few weeks, you can’t observe it from a fresh perspective anymore. You know how it is built and therefore you know exactly how it works — you have the wisdom independent testers and visitors of your site wouldn’t have.
Bottom line: if you want a great site, you’ve got to test.

DESIGN

1. Precedence (Guiding the Eye)

Good Web design, perhaps even more than other type of design, is about information. One of the biggest tools in your arsenal to do this is precedence. When navigating a good design, the user should be led around the screen by the designer. I call this precedence, and it’s about how much visual weight different parts of your design have.
A simple example of precedence is that in most sites, the first thing you see is the logo. This is often because it’s large and set at what has been shown in studies to be the first place people look (the top left). his is a good thing since you probably want a user to immediately know what site they are viewing.
But precedence should go much further. You should direct the user’s eyes through a sequence of steps. For example, you might want your user to go from logo/brand to a primary positioning statement, next to a punchy image (to give the site personality), then to the main body text, with navigation and a sidebar taking a secondary position in the sequence.
What your user should be looking at is up to you, the Web designer, to figure out.
To achieve precedence you have many tools at your disposal:

Position — Where something is on a page clearly influences in what order the user sees it.
Color — Using bold and subtle colors is a simple way to tell your user where to look.
Contrast — Being different makes things stand out, while being the same makes them secondary.
Size — Big takes precedence over little (unless everything is big, in which case little might stand out thanks to Contrast)
Design Elements — if there is a gigantic arrow pointing at something, guess where the user will look?

2. Spacing

Spacing makes things clearer. In Web design there are three aspects of space that you should be considering:

Line Spacing

When you lay text out, the space between the lines directly affects how readable it appears. Too little space makes it easy for your eye to spill over from one line to the next, too much space means that when you finish one line of text and go to the next your eye can get lost. So you need to find a happy medium. You can control line spacing in CSS with the ‘line-height’ selector. Generally I find the default value is usually too little spacing. Line Spacing is technically called leading (pronounced ledding), which derives from the process that printers used to use to separate lines of text in ye olde days — by placing bars of lead between the lines.

Padding

Generally speaking text should never touch other elements. Images, for example, should not be touching text, neither should borders or tables. Padding is the space between elements and text. The simple rule here is that you should always have space there. There are exceptions of course, in particular if the text is some sort of heading/graphic. But as a general rule, putting space between text and the rest of the world makes it infinitely more readable and pleasant.

White Space

First of all, white space doesn’t need to be white. The term simply refers to empty space on a page (or negative space as it’s sometimes called). White space is used to give balance, proportion and contrast to a page. A lot of white space tends to make things seem more elegant and upmarket, so for example if you go to an expensive arhitect site you’ll almost always see a lot of space. If you want to learn to use whitespace effectively, go through a magazine and look at how adverts are laid out. Ads for big brands of watches and cars and the like tend to have a lot of empty space used as an element of design.

3. Navigation

One of the most frustrating experiences you can have on a Web site is being unable to figure out where to go or where you are. I’d like to think that for most Web designers, navigation is a concept we’ve managed to master, but I still find some pretty bad examples out there. There are two aspects of navigation to keep in mind:

Navigation — Where can you go?

There are a few commonsense rules to remember here. Buttons to travel around a site should be easy to find – towards the top of the page and easy to identify. They should look like navigation buttons and be well described. The text of a button should be pretty clear as to where it’s taking you. Aside from the common sense, it’s also important to make navigation usable. For example, if you have a rollover sub-menu, ensuring a person can get to the sub-menu items without losing the rollover is important. Similarly changing the color or image on rollover is excellent feedback for a user.

Orientation — Where are you now?

There are lots of ways you can orient a user so there is no excuse not to. In small sites, it might be just a matter of a big heading or a ‘down’ version of the appropriate button in your menu. In a larger site, you might make use of bred-crumb-trails, sub-headings and a site map for the truly lost.

4. Design to Build

Life has gotten a lot easier since Web designers transitioned to CSS layouts, but even now it’s still important to think about how you are going to build a site when you’re still in Photoshop. Consider things like:
Can it actually be done?
You might have picked an amazing font for your body copy, but is it actually a standard HTML font? You might have a design that looks beautiful but is 1100px wide and will result in a horizontal scroller for the majority of users. It’s important to know what can and can’t be done, which is why I believe all Web designers should also build sites, at least sometimes.
What happens when a screen is resizes?
Do you need repeating backgrounds? How will they work? Is the design centered or left-aligned?
Are you doing anything that is technically difficult?
Even with CSS positioning, some things like vertical alignment are still a bit painful and sometimes best avoided.
Could small changes in your design greatly simplify how you build it?
Sometimes moving an object around in a design can make a big difference in how you have to code your CSS later. In particular, when elements of a design cross over each other, it adds a little complexity to the build. So if your design has, say three elements and each element is completely separate from each other, it would be really easy to build. On the other hand if all three overlap each other, it might still be easy, but will probably be a bit more complicated. You should find a balance between what looks good and small changes that can simplify your build.
For large sites, particularly, can you simplify things?
There was a time when I used to make image buttons for my sites. So if there was a download button, for example, I would make a little download image. In the last year or so, I’ve switched to using CSS to make my buttons and have never looked back. Sure, it means my buttons don’t always have the flexibility I might wish for, but the savings in build time from not having to make dozens of little button images are huge.

5. Typography

Text is the most common element of design, so it’s not surprising that a lot of thought has gone into it. It’s important to consider things like:
Font Choices — Different types of fonts say different things about a design. Some look modern, some look retro. Make sure you are using the right tool for the job.
Font sizes —Years ago it was trendy to have really small text. Happily, these days people have started to realize that text is meant to be read, not just looked at. Make sure your text sizes are consistent, large enough to be read, and proportioned so that headings and sub-headings stand out appropriately.
Spacing — As discussed above, spacing between lines and away from other objects is important to consider. You should also be thinking about spacing between letters, though on the Web this is of less importance, as you don’t have that much control.
Line Length — There is no hard and fast rule, but generally your lines of text shouldn’t be too long. The longer they are, the harder they are to read. Small columns of text work much better (think about how a newspaper lays out text).
Color — One of my worst habits is making low-contrast text. It looks good but doesn’t read so well, unfortunately.
Paragraphing — Before I started designing, I loved to justify the text in everything. It made for nice edges on either side of my paragraphs. Unfortunately, justified text tends to create weird gaps between words where they have been auto-spaced. This isn’t nice for your eye when reading, so stick to left-aligned unless you happen to have a magic body of text that happens to space out perfectly.

6. Usability

Web design ain’t just about pretty pictures. With so much information and interaction to be effected on a Web site, it’s important that you, the designer, provide for it all. That means making your Web site design usable.
Adhering to Standards
There are certain things people expect, and not giving them causes confusion. For example, if text has an underline, you expect it to be a link. Doing otherwise is not good usability practice. Sure, you can break some conventions, but most of your Web site should do exactly what people expect it to do!
Think about user tasks
When a user comes to your site what are they actually trying to do? List out the different types of tasks people might do on a site, how they will achieve them, and how easy you want to make it for them. This might mean having really common tasks on your homepage (e.g. ‘start shopping’, ‘learn about what we do,’ etc.) or it might mean ensuring something like having a search box always easily accessible. At the end of the day, your Web design is a tool for people to use, and people don’t like using annoying tools!

7. Alignment

Keeping things lined up is as important in Web design as it is in print design. That’s not to say that everything should be in a straight line, but rather that you should go through and try to keep things consistently placed on a page. Aligning makes your design more ordered and digestible, as well as making it seem more polished.

8. Clarity (Sharpness)

Keeping your design crisp and sharp is super important in Web design. And when it comes to clarity, it’s all about the pixels.
In your CSS, everything will be pixel perfect so there’s nothing to worry about, but in Photoshop it is not so. To achieve a sharp design you have to:
Keep shape edges snapped to pixels. This might involve manually cleaning up shapes, lines, and boxes if you’re creating them in Photoshop.
Make sure any text is created using the appropriate anti-aliasing setting. I use ‘Sharp’ a lot.
Ensuring that contrast is high so that borders are clearly defined.
Over-emphasizing borders just slightly to exaggerate the contrast.

9. Consistency

Consistency means making everything match. Heading sizes, font choices, coloring, button styles, spacing, design elements, illustration styles, photo choices, etc. Everything should be themed to make your design coherent between pages and on the same page.
Keeping your design consistent is about being professional. Inconsistencies in a design are like spelling mistakes in an essay. They just lower the perception of quality. Whatever your design looks like, keeping it consistent will always bring it up a notch. Even if it’s a bad design, at least make it a consistent, bad design.
