<hr />

<p class="intro">CSS pseudo-elements are used to add special effects
to some selectors.</p>
<hr />
<h2>Examples</h2>
<p><a target="_blank" href="tryit.asp@filename=trycss_firstletter">Make the first letter special</a><br />
This example demonstrates how to add a special effect to the first
letter of a text.</p>
<p><a target="_blank" href="tryit.asp@filename=trycss_firstline">Make the first line special</a><br />
This example demonstrates how to add a special effect to the first line of a text.</p>
<p><a target="_blank" href="tryit.asp@filename=trycss_firstline_letter">Make the 
first letter and first line special</a><br />
This example demonstrates how to add a special effect to the first letter and 
the first line of a text.</p>

<p><a target="_blank" href="tryit.asp@filename=trycss_before">Use :before to 
insert some content before the content of an element</a> (Does not work in IE)<br />
This example demonstrates how to use the :before pseudo-element to insert an 
image before an element.</p>

<p><a target="_blank" href="tryit.asp@filename=trycss_after">Use :after to 
insert some content after the content of an element</a> (Does not work in IE)<br />
This example demonstrates how to use the :after pseudo-element to insert an 
image after an element.</p>
<hr />
<h2>Syntax</h2>
<p>The syntax of pseudo-elements:</p>
<table width="100%" border="1" class="ex" cellspacing="0"><tr><td>
<pre>selector:pseudo-element {property: value}</pre>
</td></tr></table>
<p>CSS classes can also be used with pseudo-elements:</p>
<table width="100%" border="1" class="ex" cellspacing="0"><tr><td>
<pre>selector.class:pseudo-element {property: value}</pre>
</td></tr></table>
<br />
<hr />

<h2>The :first-line Pseudo-element</h2>
<p>The &quot;first-line&quot; pseudo-element is used to add special styles to the first line
of the text in a selector:</p>
<table width="100%" border="1" class="ex" cellspacing="0"><tr><td>
<pre>p:first-line {color:#0000ff;font-variant:small-caps}</pre>
<pre>&lt;p&gt;Some text that ends up on two or more lines&lt;/p&gt;</pre>
</td></tr></table>
<p>The output could be something like this:</p>
<table width="100%" border="1" class="ex" cellspacing="0"><tr><td>
<div class="ex2">Some text that ends<br />
up on two or more lines</div>
</td></tr></table>
<p>In the example above the browser displays the first line formatted according
to the &quot;first-line&quot; pseudo element. <b>Where</b> the browser breaks the line
depends on the size of the browser window.</p>
<p><b>Note:</b> The &quot;first-line&quot; pseudo-element can only be used with block-level
elements.</p>
<p><b>Note:</b> The following properties apply to the &quot;first-line&quot; pseudo-element:&nbsp;</p>
<ul>
  <li> font properties</li>
  <li>color properties&nbsp;</li>
  <li> background properties</li>
  <li>word-spacing</li>
  <li>letter-spacing</li>
  <li>text-decoration</li>
  <li>vertical-align</li>
  <li>text-transform</li>
  <li>line-height</li>
  <li>clear</li>
</ul>
<hr />

<h2>The :first-letter Pseudo-element</h2>
<p>The &quot;first-letter&quot; pseudo-element is used to add special style to the first
letter of the text in a selector:</p>
<table width="100%" border="1" class="ex" cellspacing="0"><tr><td>
<pre>p:first-letter {color:#ff0000;font-size:xx-large}</pre>
<pre>&lt;p&gt;The first words of an article...&lt;/p&gt;</pre>
</td></tr></table>
<p>The output could be something like this:</p>
<table width="100%" border="1" class="ex" cellspacing="0"><tr><td>
<div class="ex">The first words of an article...</div></td></tr></table>
<p><b>Note:</b>
The &quot;first-letter&quot; pseudo-element can only be used with block-level elements.</p>
<p><b>Note:</b> The following properties apply to the &quot;first-letter&quot; pseudo- element:&nbsp;</p>
<ul>
  <li> font properties</li>
  <li> color properties&nbsp;</li>
  <li> background properties</li>
  <li>margin properties</li>
  <li>padding properties</li>
  <li>border properties</li>
  <li>text-decoration</li>
  <li>vertical-align (only if &quot;float&quot; is &quot;none&quot;)</li>
  <li>text-transform</li>
  <li>line-height</li>
  <li>float</li>
  <li>clear</li>
</ul>
<hr />

<h2>Pseudo-elements and CSS Classes</h2>
<p>
Pseudo-elements can be combined with CSS classes:&nbsp;</p>
<table width="100%" border="1" class="ex" cellspacing="0"><tr><td>
<pre>p.article:first-letter {color:#ff0000}</pre>
<pre>&lt;p class=&quot;article&quot;&gt;A paragraph in an article&lt;/p&gt;</pre>
</td></tr></table>
<p>The example above will make the first letter of all paragraphs with class=&quot;article&quot; red.</p>
<hr />

<h2>Multiple Pseudo-elements</h2>
<p>Several pseudo-elements can be combined:</p>
<table width="100%" border="1" class="ex" cellspacing="0"><tr><td>
<pre>p:first-letter {color:#ff0000;font-size:xx-large}
p:first-line {color:#0000ff}</pre>
<pre>&lt;p&gt;The first words of an article...&lt;/p&gt;</pre>
</td></tr></table>
<p>The output could be something like this:</p>
<table width="100%" border="1" class="ex" cellspacing="0"><tr><td>
<div class="ex1">The first<br />
words of an<br />
article...</div>
</td></tr></table>
<p>In the example above the first letter of the paragraph will be red with a font size of 24pt. The rest of the first line
would be blue while the rest of the paragraph would be the default color.</p>
<hr />
<h2>CSS2 - The :before Pseudo-element</h2>
<p>The &quot;:before&quot; pseudo-element can be used to insert some content before
the content of an element.</p>
<p>The style below will play a sound before each occurrence of an &lt;h1&gt; element:</p>
<table width="100%" border="1" class="ex" cellspacing="0"><tr><td>
<p>h1:before<br />
{<br />
content: url(beep.wav)<br />
}</p>
</td></tr></table>
<br />
<hr />
<h2>CSS2 - The :after Pseudo-element</h2>
<p>The &quot;:after&quot; pseudo-element can be used to insert some content 
after the content of an element.</p>
<p>The style below will play a sound after each occurrence of an &lt;h1&gt; element:</p>
<table width="100%" border="1" class="ex" cellspacing="0"><tr><td>
<p>h1:after<br />
{<br />
content: url(beep.wav)<br />
}</p>
</td></tr></table>
<br />
<hr />
<h2>Pseudo-elements</h2>
<p>
<b>Browser support:</b> IE: Internet Explorer, F: Firefox, N: Netscape.</p>
<p>
<b>W3C:</b> The number in the &quot;W3C&quot; column indicates in which CSS recommendation 
the property is defined (CSS1 or CSS2).</p>

<table class="ex" cellspacing="0" border="1" width="100%" cellpadding="3">
  <tr>
    <th align="left" valign="top" width="25%">Pseudo-element</th>
    <th align="left" valign="top" width="55%">Purpose</th>
