Can someone try this code and let me know if you also have an offset of three pixels after the IFrame and the next cell, which contains Test?
<!DOCTYPE HTML>
<html>
<head>
<Base HRef="http://localhost/YourWebSite/"></Base>
<Style>
BODY
{
Padding-Top: 0px;
Padding-Left: 0px;
Padding-Right: 0px;
Padding-Bottom: 0px;
Margin-Left: 0px;
Margin-Right: 0px;
Margin-Top: 0px;
Margin-Bottom: 0px;
}
</Style>
</head>
<body>
<table cellspacing=0 cellpadding=0>
<tr>
<td height="22">
<iframe src="YourPage.aspx" frameBorder="0" scrolling="no" width="100%" height="22"></iframe>
</td>
</tr>
<tr>
<td>
Test
</td>
</tr>
</table>
</body>
</html>Simply replace YourPage.aspx with one that is valid. If you want to see it more clearly, you can add Border=1 in the table tag as well as replacing frameBorder=0 with frameBorder=1. You will see there is a 3 pixels gap between the two. I have the same all over the entire setup. I just provided a simple version to test with. I have the same with IE, Firefox and Chrome.
There must be something I am missing. This is cause by the IFrame tag. If you remove it, the gap is gone. So, this is related to that. I also try to add the four additional attributes to the tag such as vspace, hspace, etc. to be all equal to 0. This doesn't change anything.
