I'm not a webmaster, not even a web developer, but I'm tasked with adding content to a Wordpress site developed by Someone Else(TM).

Here's a page illustrating the problem: http://www.reginedagan.no/program/fiskekonkurranse-i-hovden/.

It shows up nice in Firefox:

But in IE9 the floated picture pushed down the text in the table below, so that it looks rather awful:

I found some related questions on the web, e.g. "CSS: Float right in IE doesn't work!" and "why does a floating DIV mess up table positioning?", and the suggestions there led me to set clear: none on the div around the table, the table itself, and then each individual tr and finally even on each individual td. I also set width="99%" on the table, and tried (but I don't know how correctly) to apply the IE6 quirk fix margin-right: -3px.

So here's the content as written in Wordpress, including the unsuccessful attempted fixes:

<h1><div style="float: right"><a href="http://www.reginedagan.no/?attachment_id=671"><img src="http://www.reginedagan.no/wp-content/uploads/2012/06/fiskekonkurranse-2011-bilde-3-nedskalert.jpg" alt="Fra fiskekonkurransen i 2011" title="Fra fiskekonkurransen i 2011" width="200" height="242" class="size-full wp-image-671"/></a></div>Fiskekonkurranse i Hovden!</h1>
<div style="background-color: #FAF0F0; clear: none;"><table width="99%" style="clear: none; right-margin: -3px;">

And the resulting HTML served to a browser (only the relevant first part):

<div style="float: right;"><a href="http://www.reginedagan.no/?attachment_id=671"><img src="http://www.reginedagan.no/wp-content/uploads/2012/06/fiskekonkurranse-2011-bilde-3-nedskalert.jpg" alt="Fra fiskekonkurransen i 2011" title="Fra fiskekonkurransen i 2011" class="size-full wp-image-671" height="242" width="200"></a></div>
<p>Fiskekonkurranse i Hovden!</p></h1>
<div style="background-color: rgb(250, 240, 240); clear: none;">
<table style="clear: none;" width="99%">
<tbody><tr style="clear: none;">
<td style="text-align: left; clear: none;">Dato:</td>
<td style="text-align: left; clear: none;">Lørdag 21.juli</td>
</tr>

The able to reproduce the effect with simpler code by setting clear: right on the table. However, I'm unable to reproduce the effect with default styling or with clear: none (as above). So it seems maybe it's something Wordpress does, or maybe it's something the theme thing or whatever it is does – but it's very similar to what others have observed, so there is strong indication that it's also a quirk in IE.

Help?
