CSS is pretty simple stuff, though.
Take a look at the following sample of code taken from your website, and the sample immediately thereafter, which is simplified with CSS:
PHP:
<table width="800">
<tbody>
<tr bgcolor="#bf4040">
<th width="190"><font face="calibri" color="#ffffff"><strong>Feature</strong></font></th>
<th width="120"><font face="calibri" color="#ffffff"><strong>Basic</strong></font></th>
<th width="120"><font face="calibri" color="#ffffff"><strong>Premium</strong></font></th>
<th width="120"><font face="calibri" color="#ffffff"><strong>Silver</strong></font></th>
<th width="120"><font face="calibri" color="#ffffff"><strong>Gold</strong></font></th>
<th width="120"><font face="calibri" color="#ffffff"><strong>Platinum</strong></font></th></tr>
<tr>
<td bgcolor="#40bfbf"><strong><font face="calibri" color="#ffffff">Diskspace</font></strong></td>
<td><font face="calibri">3 Gb</font></td>
<td><font face="calibri">5 GB</font></td>
<td><font face="calibri">8 GB</font></td>
<td><font face="calibri">12 GB</font></td>
<td><font face="calibri">20 GB</font></td></tr>
<tr>
<td bgcolor="#40bfbf"><strong><font face="calibri" color="#ffffff">Bandwidth</font></strong></td>
<td><font face="calibri">100 GB</font></td>
<td><font face="calibri">150 GB</font></td>
<td><font face="calibri">200 GB</font></td>
<td><font face="calibri">250 GB</font></td>
<td><font face="calibri">350 GB</font></td></tr>
...
</table>
Code with CSS Styles (I've put this in the <head> element, but you should probably put it in an external CSS file).
PHP:
// CSS code
<head>
<style>
table.features {
width: 800px;
font-family: "Calibri", serif;
}
table.features tr.header {
background: #bf4040;
}
table.features tr.header th {
color: #fff;
}
table.features tr td.item {
background: #40bfbf;
color: #fff;
font-weight: bold;
}
</style>
</head>
// HTML code
<table class="features">
<tbody>
<tr class="header">
<th width="190">Feature</th>
<th width="120">Basic</th>
<th width="120">Premium</th>
<th width="120">Silver</th>
<th width="120">Gold</th>
<th width="120">Platinum</th>
</tr>
<tr>
<td class="item">Diskspace</td>
<td>3 Gb</td>
<td>5 GB</td>
<td>8 GB</td>
<td>12 GB</td>
<td>20 GB</td>
</tr>
<tr>
<td class="item">Bandwidth</td>
<td>100 GB</td>
<td>150 GB</td>
<td>200 GB</td>
<td>250 GB</td>
<td>300 GB</td>
</tr>
...
</tbody>
</table>
Of course, the code probably needs some refining seeing that I just typed it into a forum box.
But you can see how much easier it is handling styles. Of course, I guess this is the way your WYSIWYG editor does it. What are you using btw?
