There is one WordPress feature that was introduced that always made me curious: the image alignment feature of the “Add media” editor. Why? Because it never worked!
I knew that I was probably doing something wrong, but since I didn’t have time to find it out, I just kept choosing “none” as the alignment, and then I would manually insert the right, left or center alignment attribute on the image tag.
Then last week when I was submitting one of my themes for the WordPress Themes Directory I got a message saying that WordPress themes were required to have the following code on their stylesheet:
margin: 0 0 2px 7px;
margin: 0 7px 2px 0;
Duh! That is why the alignment feature was not working on my blogs, I never added that code! Now if you faced this problem in the past, now you know how to solve it.
