Trang 2

Designing for the Real

World

In previous lessons, you learned about what you should and shouldn’t do

when you plan your website and design your pages You also learned

about what makes a good or bad website There’s another important

fac-tor that you should take into consideration, and that’s how to design your

pages for the real world

You’ve already learned that the real world consists of many different

users with many different computer systems who use many different

browsers Some of the things we haven’t yet addressed, however, are the

many different preferences and experience levels that the visitors to your

site will have By anticipating these real-world needs, you can better judge

how you should design your pages I also explain how you can make sure

that your websites are usable for people who are disabled and must use

accessibility technologies to browse the Web

In this lesson, you’ll learn some ways that you can anticipate these

needs, as well as the following:

n Things to consider when you’re trying to determine the

prefer-ences of your audience

n Various ways of helping users find their way around your site

n HTML code that displays the same web page in each of the

XHTML 1.0 specifications (Transitional, Frameset, and Strict)

n What accessibility is, and how to design accessible sites

n Using an accessibility validator

What Is the Real World, Anyway?

You’re probably most familiar with surfing the Internet on a computer that runs a specific

operating system, such as Windows, Mac OS X, or something similar You might think

you have a pretty good idea of what web pages look like to everyone

Throughout this book, you’ve learned that the view you typically see on the Web isn’t

the view that everyone else sees The real world includes many different computers with

many different operating systems Even if you try to design your pages for the most

com-mon operating system and the most comcom-mon browsers, there’s another factor that you

can’t anticipate: user preference Consider the following family, for example:

n Bill is a top-level executive at a Fortune 100 company that has its own intranet

The company IT department requires everyone to use the same operating system

and the same browser Bill is mainly interested in getting news online, and doesn’t

bother with multimedia He’s also addicted to his smartphone, constantly checking

his email and using it to get news on the Web when he’s not at his desk

n Bill’s wife, Susan, uses her computer mainly for email She follows links that she

gets from other people, but she’s not comfortable “surfing” the Web She’s a

genealogist by hobby and has learned that the Internet has many resources in that

field She also wants to publish her family history on the Web When she and her

husband got their cable modem hooked up, she was thrilled But soon she was

ask-ing questions such as, “Can we fit more on the screen? Those letters are a bit too

small…can we make them larger? Where are the pictures? How come you have the

music turned off? It says that there’s sound on this page!” She already wanted to

see the Internet much differently than what her husband was used to seeing

n Bill and Susan have a son, Tom, who’s in high school He’s an avid gamer and

spends a lot of time watching videos on YouTube! He pumps up the volume as

loud as he can and pushes the capacities of their new computer to the max He also

thinks “Browser X” is better than “Browser Y” because it supports lots of

cutting-edge features He wants to start a blog that provides hints, tips, and tricks for one

of his favorite online games

n Tom’s older sister, Jill, is an art major in college, studying to be a commercial

artist She has a keen interest in sculpture and photography She plans to use her

new computer for homework assignments, so she’ll be looking at the Web with a

keen visual interest She also uses Facebook and Twitter to stay in touch with her

friends from school

n Then there are the senior members of the family, Susan’s aging parents, who have

recently moved in with the family after years of living in a rural town Their

experience with computers is minimal—they don’t even have their own email

addresses They’re interested in learning so that they can view family photos online

and exchange email with out-of-town relatives, but Dad’s eyes aren’t quite as sharp

as they used to be He needs a special browser so that he can hear the text as well

as see it

All these people are using the same computer and operating system to view the Web In

all cases but one (young Tom), they’re also using the same browser This example

illus-trates one of the other things that you need to think about when you design your website:

the needs of the users themselves Some of these needs are easier to accommodate than

others The following section describes some of the considerations you saw in the

previ-ous example

Considering User Experience Level

There are varied levels of experience in our fictitious family Although everyone is

keenly interested in the Web, some of them have barely used a web browser When you

design your site, consider that the people who visit it might have varying levels of

expe-rience and browsing requirements

Will the topics that you discuss on your site be of interest to people with different levels

of experience? If so, you might want to build in some features that help them find their

way around more easily The key, of course, is to make your navigation as intuitive as

possible By keeping your navigation scheme consistent from page to page throughout

the site, you’ll do a favor for users of all experience levels There are a number of

fea-tures you can add to your site that will improve its usability for everyone

Add a Search Engine

Many users go straight to the search engine when they want to find something on a site

No matter how much time and effort you put into building a clear, obvious navigation

scheme, someone looking for information about Frisbees is going to look for a box on

your page where they can type in the word Frisbee and get back a list of the pages where

you talk about them

Unfortunately, locating a good search engine package and setting it up can be an awful

lot of work, and difficult to maintain On the other hand, there are some alternatives

Some search engines enable you to search a specific site for information You can add a

link to them from your site Some search engines even allow you to set things up so that

you can add their search engine to your site, such as Google:

http://www.google.com/cse/

Trang 5

By signing up, you can add a search box to your site that enables your users to search

only pages on your own site for information For a list of other ways to add search

func-tionality to your site, see the following page in the Open Directory Project:

http://www.dmoz.org/Computers/Software/Internet/Servers/Search/ Use Frames Wisely

One failing of some Hypertext Markup Language (HTML) books is that they tell you

about all the different techniques you can use to create web pages, but they don’t offer

any comparative information that explains when and how these techniques ought to be

used For example, I’ve devoted a number of pages to discussing frames, but they should

really be used only when nothing else will work For example, putting all of your

naviga-tion in one frame and your content in another just because you can is generally a poor

idea

Frames have a couple of specific disadvantages that make them unsuitable for use in

many cases The first is that they make it hard for users to bookmark inner pages on

sites If your entire site is a frameset, the URL in the user’s location bar never changes as

the user navigates within the site When the user gets to your inner page that has a

won-derful recipe for chocolate chip cookies that your grandmother gave you, he’ll have a

hard time bookmarking it because his browser wants to bookmark the top-level frameset

itself When he returns on future visits, he’ll be taken back to your home page

The second issue that’s common with framesets is that they can interfere with search

engines Again, if your entire site is inside a frameset, when a search engine fetches your

home page, it’s probably going to get a page with no real content to speak of Then, it

will download, say, the navigation frame, which lacks context, the content frame, which

may lack header and footer information, and on and on If you want people to find your

site using search engines, frames can get in your way

There are also other issues people have had with framesets in the past, like problems

printing and problems with the back button Browsers mostly compensate for these

issues today, but even so, frames can confuse your users In some cases, there’s just no

other good way to attack a problem, but you should always make sure that there’s not a

better way before going the frames route

Use Concise, Sensible URLs

One common mistake made by web designers is not considering how users share URLs

If your site is interesting at all, people are going to email the URL to their friends, paste

it into instant messaging conversations, and talk about it around the water cooler Making

your URLs short and easy to remember makes them that much easier for people to share

There’s a reason why people have paid huge sums for domain names like business.com

andcomputers.comin the past They’re easy to remember and you don’t have to spell

them out when you tell them to people

570 LESSON 19: Designing for the Real World

Trang 6

You may not have any control over your domain name, but you can exercise control over

the rest of your URLs Say that you have a section of your site called “Products and

Services.” All the pages in that section are stored in their own directory You could call it

any one of the following:

/ps

/prdsvcs

/products

/products_services

/products_and_services

There are plenty of other options, too (you could call it /massapequaif you wanted to),

but the preceding list seems like a reasonable group of options Of the list, a few stand

out to me as being poor choices /products_serviceand/products_and_servicesjust

seem too verbose If the pages under those directories have long names, you’re suddenly

in long URL territory, which isn’t conducive to sharing On the other hand /prdsvcs

may be short, but it’s also difficult to remember and almost certainly has to be spelled

out if you tell it to anyone It’s probably no good That leaves two remaining choices:

/psand/products The first, /ps, is nice and short, and probably easy to remember

Using it would be fine However, there’s one other principle of URLs that I want to talk

about: guessability

Chances are that most of the people who visit your website have been using the Web for

awhile There’s some chance that they might just assume that they know where to go on

your site based on experience If they want to read about your products, they may

guess—based on their experience with other sites they’ve visited—that your products

will be listed at http://www.your-url.com/products Any time you can put your

con-tent where your users will assume it to be, you’re doing them a favor Using standard

directory names such as /about,/contact, and /productscan make things ever so

slightly easier for your users at no cost to you

My final bit of advice on URLs is to make sure that they reflect the structure of your site

One time I worked on a site that consisted of hundreds of files, all in a single directory

The site itself had structure, but the files were not organized based on that structure

Whether the user was on the home page or five levels deep within the site, the URL was

still just a filename tagged onto the hostname of the server Not only did this make the

site hard to work on, but it also kept some useful information away from users Suppose

you have a site about cars What’s more useful to your users?

http://www.example.com/camry.html

or

http://www.example.com/cars/toyota/2009/camry.html

Trang 7

The second URL provides a lot more information to the user than the first one does As

an added bonus, you can set up your site so that the user can take camry.htmloff the end

and get a list of all Toyota models for 2009, or take toyota/2009/camry.htmloff the

end and get a list of all car makes discussed on the site Veteran web users are

accus-tomed to dealing with URLs; you should help them out as much as you can by using

URLs responsibly

Navigation Provides Context

The key purpose of navigation is obviously to enable your users to get from one place to

another within your site However, its secondary purpose is to let your users know where

they are within the site This was the stroke of genius behind Yahoo!’s introduction of

“breadcrumb” navigation in its directory Take a look at the screenshot from Yahoo!’s

directory in Figure 19.1

572 LESSON 19: Designing for the Real World

FIGURE 19.1

A page from

Yahoo!’s directory.

Near the top, you can see a list of links that start at the top of the directory and lead

down to the page that I’m actually on The first thing it does is give me the ability to go

back to any level of the directory between the home page and the Cascading Style Sheets

page that I’m actually on The second thing it does is let me know that I’m six levels into

the directory, and that the page I’m on is part of the Arts category of the directory, and

all the subcategories between that category and the page that I’m on That’s a lot of

util-ity packed into a small feature

Trang 8

Not all sites have as large and complex a structure as Yahoo!, but you can still provide

context for your users through your navigation scheme By altering your navigational

elements based on the page that the user is on, you can indicate to them not only where

she can go but also where she is This is also particularly helpful to users who arrive at

your site not via the home page, but from an external link Enabling users to immediately

deduce where they are in the larger scheme of things makes it more likely that they’ll

take in more of your site

Are Your Users Tourists or Regulars?

When you’re designing a site, especially one that uses forms, one of the key questions

you have to ask yourself is whether your users are tourists or regulars If your users are

tourists, which means that they don’t use your site very often, or will probably only ever

use it one time, you should design your site so that the first-timer can easily figure out

what he should be doing and where he needs to go This may annoy regular users who

already know where they’re going, but in some cases you have to cater to tourists

On the other hand, if your site is normally used by the same existing group of users who

come back once a day or once a week, your emphasis should be on providing shortcuts

and conveniences that enable them to use your site as efficiently as possible It’s okay if

it takes a bit of work to learn about the conveniences, because it’s worth your users’

time

Clearly, the secret is to strike a balance here The holy grail is a site that’s obvious and

clear to new users but also provides the features that repeat users crave However,

under-standing what sort of audience you have can help you determine how to assign your

resources

All of this is doubly true with forms The forms that are part of a discussion board used

by the same people day after day will be designed much differently from those that are

part of a request-more-information form on a product page When you design a form,

always think about the type of user who’ll be using it

Determining User Preference

In addition to the various levels of experience that visitors have, everyone has his own

preferences for how he wants to view your web pages How do you please them all? The

truth is, you can’t But you can give it your best shot Part of good web design is

antici-pating what visitors want to see on your site This becomes more difficult if the topics

you discuss on your site are of interest to a wider audience

Trang 9

You’ll notice that each person in our fictitious family needs to see the Web differently

Sometimes this is due to his or her interests, but other times it’s because of special needs

Therein lies the key to anticipating what you’ll need on your web pages

A topic such as “Timing the Sparkplugs on Your 300cc Motorcycle Engine” is of interest

to a more select audience It will attract only those who are interested in motorcycles—

more specifically, those who want to repair their own motorcycles It should be relatively

easy to anticipate the types of things these visitors would like to see on your site

Step-by-step instructions can guide them through each process, while images or multimedia

can display techniques that are difficult to describe using text alone

“The Seven Wonders of the Ancient World,” on the other hand, will attract students of all

ages as well as their teachers Archaeologists, historians, and others with an interest in

ancient history also might visit the site Now you have a wider audience, a wider age

range, and a wider range of educational levels It won’t be quite as easy to build a site

that will please them all

In cases such as this, it might help to narrow your focus a bit One way is to design your

site for a specific user group, such as the following:

n Elementary school students and their teachers—This site requires a basic

navi-gation system that’s easy to follow Content should be basic and easy to read

Bright, colorful images and animations can help keep the attention of young visitors

n High school students and their teachers—You can use a slightly more advanced

navigation system Multimedia and the latest in web technology will keep these

students coming back for more

n College students and their professors—A higher level of content is necessary,

whereas multimedia may be less important Properly citing the sources for your

information will be important

n Professional researchers and historians—This type of site probably requires

pages that are heavier in text content than multimedia

It’s not always possible to define user groups for your website, so you’ll need to start

with your own preferences Survey other sites that include similar content As you

browse through them, ask yourself what you hope to see there Is the information

dis-played well? Is there enough help on the site? Does the site have too much or too little

multimedia? If you can get a friend or two to do the survey along with you, it helps you

get additional feedback before you start your own site Take notes and incorporate those

ideas into your own web pages

574 LESSON 19: Designing for the Real World

Trang 10

After you design some initial pages, ask your friends, family members, and associates to

browse through your site and pick it apart Keep in mind that when you ask others for

constructive criticism, you might hear some things that you don’t want to hear However,

this process is important because you’ll often get many new ideas on how to improve

your site even more

Migrating to HTML5

One big question facing web developers right now is whether to start using HTML5 or to

stick with XHTML 1.0 (or even HTML 4.01) HTML5 is the path forward for HTML,

but it has not quite arrived Work on it started in 2004, and as of February 2010, it was in

last call status with the WHATWG, the group that is drafting the specification After the

specification is finalized, browsers will need to add support for the new features in the

specification

Benefits of HTML5

Why are browser makers and interested publishers spending years coming up with a new

version of HTML? In the earlier days of the Web, new features were added to HTML

regularly without much regard for the standards process Frames were created because

Netscape thought it would be a good idea to add a feature that allowed publishers to put

ads on the page that would move out of sight when users scrolled down the page

Microsoft added the basefonttag to HTML so that authors could specify the font for a

page in one location before support for CSS was added to browsers Furthermore,

browser makers added support for the same tags in different ways, so HTML looked

dif-ferent depending on the user’s browser HTML5 will contain only features that the

mak-ers of all the major browsmak-ers have agreed to support, so it allows HTML to move forward

without the browser wars that were one of the worst things about the early Web Having

said that, browsers will probably implement the new features in HTML5 on different

schedules Mobile Safari, the browser on Apple’s iPhone, already supports a number of

the new features in HTML5 Google Chrome, Apple Safari, and Firefox all support

HTML5, as does Internet Explorer 9

HTML5 introduces a number of new tags that more accurately reflect the way pages are

built now Most designers build pages using lots of <div>tags with classes and IDs that

describe the purpose of those elements HTML5 adds tags like <article>,<header>,

<footer>,<nav>, and <section> Browser support for the new elements is limited, but

they will be supported eventually
