Hi Mohamed, I fixed up your code for you so we can see it a little better. Check out the Markdown Cheatsheet link below, to see how to format code in the forums.

Which browser are you using?

If you're trying this in Firefox or Internet Explorer, (possibly even Chrome) it won't work because of the "-webkit" animation prefix.

Safari is the only browser that truly now supports the "-webkit" prefix. Most Chrome properties are now unprefixed or at very least the "-webkit" is deprecated, since it moved to the Blink engine.

Hi Mohammed,

We really need more information to go on. What is wrong doesn't really give us a clue about the issue your having.
