Thanks.

The reason I wanted this was I had to put
<div id="categoriesContent" class="sideBoxContent">
In my header. When I found the source php file that was creating the categories box and copied the content into my header file, it didnt work.

So that my menu can be fluid I dont want a width value for this div so ive changed the following;

<div class="rightBoxContainer" id="<?php echo str_replace('_', '-', $box_id ); ?>" style="width: <?php echo $column_width; ?>">

<div class="rightBoxContainer" id="<?php echo str_replace('_', '-', $box_id ); ?>" style="">

I first tried to use CSS to override the PHP but the following didn't work;
.rightBoxContainer, #categories {
width: 100%;
}


So long as this hasn't caused problems for me down the line, it seems to be working fine.

In future, would it be possible to use CSS to override the PHP so I dont have to edit the PHP code?

thanks
