Yeahh, that worked, I think we got closure on this. One side note, the original class in this template needed to be replaced rather than added (appended) to, as the script would always call the original class unless it was deleted even after updating the system module.

I can now adjust the width at will, and while I have not tried, I suppose it is also possible to use the width: 100%; or width: auto; as well.

Thanks irmtfan, flipse, and Mamba. It definitely looks professional now rather than like a hastily construed hack.

Whoever oversees what gets carried forward into future releases (Cesag? Mamba?) might want to schedule this into the next one so it gets propagated. I realize that the larger side of the issue rests in the theme side of things rather than XOOPS itself.

yes, width: 100%; width: 90% will be the best solution.

as you can see it should be in template not in php file. then you can customize it easily.
