description space under an image

Generally, yes, you can do that in the CSS code — but specifics would depend on your site. Can you post a link to a page where you want to change this?

It looks like that space is being limited by the height set in the CSS for the thickbox gallery here:

#TB_caption {
    float: left;
    height: 25px;
    padding: 7px 30px 10px 25px;
}

So try adding this to your child theme CSS:

#TB_caption {
    height: auto;
}

That should (hopefully) make it expand to fit however long a caption you enter.

That was a bit of a disaster – and I’m not sure how to get back.

It did do what we wanted it to do, but turned the rest of the site into chaos – I’ve re-edited the CSS to get rid of the addition, but at present it is still a mess and I don’t know how to fix it – any ideas? I’ll try cleani9ng my cache unless it is a problem there.

OK – rebuilt the style.css and all is back to normal, but this problem (ie description space) remains ??
