CSS CSS Selectors Going Further with Attribute Selectors and Pseudo-Classes :only-child and :empty

I did a :empty and expect it to affect my <h1></h1>, but it did not. Any ideas why?

As the title goes: I did a :empty and expect it to affect my <h1></h1>, but it did not. Any ideas why?

As far as I know, h1 is a block level so it should display the bg color I added for :empty. Also did it in <span></span> and in <ul></ul> but it did just not affect the empty tags.

If the tag is empty ie <h1></h1> it won't be shown unless it has a width or height set. Try something like this to test

H1 { width: 100px; height: 100px; }
H1:empty { background-color: #333; }

It's hard to say without seeing the code :) Perhaps you had some whitespace between the tags?
