Twenty Twelve - single attachment page displays empty sidebar

[TomasM]

From the code in the image.php we see that sidebar should not be loaded, but content is still narrow.

To fix this issue line 1457 in style.css:

	body.single-attachment .site-content,

should be replaced with:

	body.attachment .site-content,

Bug is valid. To recreate, view an image attachment that has a page as its parent.

Twenty Twelve: Use the correct body class for attachments.

.single-attachment is only used when the attachment's parent is not a page.

Reopening for Twenty Ten, Twenty Thirteen, and the IE stylesheet in Twenty Twelve.

Replying to nacin:

Reopening for Twenty Ten, Twenty Thirteen, and the IE stylesheet in Twenty Twelve.

Twenty Ten defines .single-attachment manually in its attachment.php file and uses a selector that is specific to the markup there. It does not necessarily need fixing.

Fixes for Twenty Thirteen and the IE stylesheet in Twenty Twelve.

[obenland]

Updated patch from Marco_Teethgrinder. We can remove the selector in Twenty Thirteen entirely since the right sidebar never gets loaded on image attachment pages.
