Yes.
However they will only display in IE. If you don't have an image editor you can create it
in FP and then take a screenshot and paste it into paint or IrfanView, then "cut" the part
you want and save it as an image.
Here's one that is blue at the left and fades to white.
<table border="0" cellpadding="0" cellspacing="0" style="border-collapse: collapse"
bordercolor="#111111" width="100%" id="AutoNumber2">
<tr>
<td width="100%"id=msviRegionGradient1 style="FILTER:
progid

XImageTransform.Microsoft.Gradient(startColorStr='#0000ff',
endColorStr='#FFFFFF',gradientType='1')"> </td>
</tr>
</table>
To make the gradient verticle change gradientType='1' to gradientType='0'
To play twith the colors, change the hex values for: startColorStr and?:
endColorStr
