<h1>HTML Backgrounds</h1>
<a href="html_images.asp"><img border="0" src="../images/btn_previous.gif" width="100" height="20" alt="Previous" /></a>
<a href="html_colors.asp"><img border="0" src="../images/btn_next.gif" width="100" height="20" alt="Next" /></a>
<hr />

<p class="intro">A good background can make a Web site look really great.</p>
<hr />

<h2>Examples</h2>

<p><a target="_blank" href="tryit.asp@filename=tryhtml_back_good">Good background and text color</a><br />
An example of a background color and a text color that makes the text on the
page easy to read.&nbsp;
</p>

<p><a target="_blank" href="tryit.asp@filename=tryhtml_back_bad">Bad background and text color</a><br />
An example of a background color and a text color that makes the text on the
page difficult to read.&nbsp;</p>

<p>(You can find more examples at the bottom of this page)</p>

<hr />

<h2>Backgrounds</h2>

<p>The &lt;body&gt; tag has two attributes where you can specify backgrounds.
The background can be a color or an image.</p>
<h3>Bgcolor</h3>
<p>The bgcolor attribute specifies a background-color for an HTML page. The value of this
attribute can be a hexadecimal number, an RGB value, or a color name:</p>
<table width="100%" class="ex" cellspacing="0" border="1">
    <tr>
      <td>
        <pre>&lt;body bgcolor=&quot;#000000&quot;&gt;
&lt;body bgcolor=&quot;rgb(0,0,0)&quot;&gt;
&lt;body bgcolor=&quot;black&quot;&gt;</pre>
      </td>
    </tr>
</table>
<p>The lines above all set the background-color to black.&nbsp;</p>
<h3>Background</h3>
<p>The background attribute specifies a background-image for an HTML page. The value of this
attribute is the URL of the image you want to
use.&nbsp;If the image is smaller than the browser window, the image will repeat
itself until it fills the entire browser window.</p>
<table width="100%" class="ex" cellspacing="0" border="1">
    <tr>
      <td>
        <pre>&lt;body background=&quot;clouds.gif&quot;&gt;
&lt;body background=&quot;http://www.w3schools.com/clouds.gif&quot;&gt;</pre>
      </td>
    </tr>
</table>

<p>The URL can be relative (as in the first line above) or absolute (as in the
second line above).</p>
<p><b>Note: </b>If you want to use a background image, you should keep in mind:</p>
<ul>
  <li>Will the background image increase the loading time too much?</li>
  <li>Will the background image look good with other images on the page?</li>
  <li>Will the background image look good with the text colors on the page?</li>
  <li>Will the background image look good when it is repeated on the page?</li>
  <li>Will the background image take away the focus from the text?</li>
</ul>

<h2>Basic Notes - Useful Tips</h2>
<p>The bgcolor, background, and the text attributes in the &lt;body&gt; tag are deprecated in the latest versions
of HTML (HTML 4 and XHTML). The World Wide Web Consortium (W3C) has removed these
attributes from its recommendations.</p>
<p>Style sheets
(CSS) should be used instead (to define the layout and display properties of 
HTML elements).</p>
<hr />

<h2>More Examples</h2>

<p><a target="_blank" href="tryit.asp@filename=tryhtml_back_img">Good background image</a><br />
An example of a background image and a text color that makes the text on the
page easy to read.&nbsp;
</p>

<p><a target="_blank" href="tryit.asp@filename=tryhtml_back_img2">Good background image 2</a><br />
An example of a background image and a text color that makes the text on the
page easy to read.&nbsp;
</p>

<p><a target="_blank" href="tryit.asp@filename=tryhtml_back_imgbad">Bad background image</a><br />
An example of a background image and a text color that makes the text on the
page very difficult to read.&nbsp;
</p>

<h2>Computer Joke</h2>
<p><b>Support:</b> &quot;Type dir, space, a, colon.&quot;</p>
<p><b>Customer:</b> &quot;With a space after 'space'?&quot;</p>
