Problem with display of shaded panels created with CSS code

Running: Win XP (Home)
Firefox 2.0.0.3 also IE 7.0

Knowledge very limited, however, have been using a simple code to created shaded panels in my blog. Recently, after I replaced my CRT with a flat panel, I can no longer see the shaded panels (I see an indented paragraphs)but visitors to the site can. The code:

<table align=”center” cellpadding=”3”>
<tbody>
<tr>
<td bgcolor=”azure” width=”565”>

</td></tr></tbody></table>

My PC is limited to max resolution 1280x1024; I have it set at 1152x864.

Shall be grateful for advice/suggestions. Thanks
