<h1>Web Quality - Accessibility (WAI)</h1>

<p class="intro">An accessible web site is a web site that can be used by
disabled users.</p>
<p class="intro">Disabled users are users with disabilities or bad user
conditions. </p>
<hr />
<h2>The Web Accessibility Initiative - WAI</h2>
<p>WAI (created by the World Wide Web Consortium (W3C) in 1997) is a set of
guidelines intended for web developers, authors, and designers-
about how to make web content accessible to people with disabilities.</p>
<p>The goal of these guidelines is accessibility, but they will also help make
web contents available to more browsers (voice browsers, cell phones, hand-held
devices), and to more users working in difficult environments (hands-free,
strong light, darkness, bad sight, heavy noise). </p>
<hr />
<h2>Is WAI Important to Your Web Site?</h2>
<p>Yes it is.</p>
<p>Millions of people with disabilities are surfing the Internet every day, and
even more millions are using poor browser equipment, or working under difficult
user environments. </p>
<p>If your website lacks features such as resizable fonts, images with proper
text descriptions, and easy navigation, these people will not be able to access your
information. </p>
<p><img border="0" src="../images/lamp.gif" alt="lamp.gif" /> In fact: <b>Your site
violates the rights of these people</b>.</p>
<p>Here are some other reasons for making your site more accessible:</p>
<ul>
<li>It will improve your reputation and image</li>
<li>It will improve your customer satisfaction</li>
<li>It will increase your number of visitors</li>
<li>It will let your visitors stay longer at your site</li>
<li>It will increase the number of returning visitors</li>
<li>It will make your site more usable also for people with no disabilities</li>
<li>It will make your site more usable for users with images turned
off</li>
<li>It will make your site more usable for people with older equipment</li>
<li>It will let you reach the fastest growing population: older people </li>
</ul>
<hr />
<h2>Use an Adjustable Font Size</h2>
<p>Use only relative font sizes, and let the user be able to use the browser
menu (View - Text Size) to change the default text size.</p>
<p style="font-size:large">Can you read this?</p>
<p style="font-size:small">Can you read this?</p>
<p style="font-size:x-small">Can you read this?</p>
<p style="font-size:xx-small">Can you read this?</p>
<p><img border="0" src="../images/lamp.gif" alt="lamp.gif" /> To change the font
size, select view - text size - in your browsers menu.</p>
<hr />
<h2>Use The "alt" Attribute</h2>
<p>The alt attribute allows you to provide a text equivalent for an image (and
for some other elements).</p>
<p>Example:</p>
<table width="100%" border="1" class="ex" cellspacing="0"><tr><td>
<pre><img src="images/bana.jpg" alt="Banana" /></pre>
</td></tr></table>
<p>
Sometimes a web browser will not display your images. The reason could be one of
many:</p>
<ul>
<li>The user has turned off the display of images</li>
<li>The browser is a mini browser without image display.</li>
<li>The browser is a voice browser (used by blind or poor-sighted)</li>
</ul>
<p>
If you use the "alt" attribute, most browsers will at least display or read the
"alt" description.</p>
