I am baffled by a problem I have where divs are not being applied in my WordPress blog, which uses a Child theme of the twentyeleven theme (the new default).
The posts I am concerned about should have a small div floated to the right at the top of the content showing Hot News Items.
I am using a child theme and I have included in the style.css the following:
[CSS code moderated - a link to your site is sufficient to access the stylesheet]
This used to work well in a theme I used before, but seems to be not taken into account using the twentyeleven theme.
You can see an example in the following post:
If you check the source, you will see that the divs with appropriate classes all appear there.
