Bad float styling in Media Library?

[dougal]

Observed in Firefox 3.6.3, but not in Chrome.

When browsing the media library, the thumbnails can exhibit a "stairstep" effect, due to being larger than their containing div.

It appears that this stems from an element style in the get_media_item() function of wp-admin/includes/media.php (line 1232). The inline style on the image gives a margin-top of 3px. But there is already a stylesheet style which gives an all-around margin of 2px. I believe that the 2px value is correct.

The containing element is getting its 36px height from the image name and the 'show/hide' link. But the thumbnail images (or 'pinkynail' images, as the CSS class calls them) are 32px square, plus the margins. The stylesheet margins would be 2px each for top and bottom, and so would also be 36px. But the inline style giving 3px for the margin-top results in a 37px height, causing the floated image to "poke out" of the bottom, so that the next image moves right to accommodate it.

The inline style seems unnecessary anyhow. So my patch simply removes it. Another option would be to add a "clear: left" to the #media-items .media-item rule in wp-admin/css/media[.dev].css.

The problem still exists. Take a look at ​http://wojtekszkutnik.com/temp/20100812-99c-2kb.jpg - it's an example from my media gallery. Clearly, the top margin is too big.

Refreshing the patch

This bug is ancient, and I haven't seen it happen in a long time. Going to go ahead and flag it as fixed.

Appears to be fixed in [19262] (the change suggested in 12861.diff​ was made there).
