Hi friends…
I want to display My top menu such as “Home”,“About Us” till “Contact Us” display horizontally but I displays in different lines…
How I Can made it…
Plz help…

You have some item end tags missing that causes the problem. Also wrap the spans in a paragraph, they are not allowed to be siblings to block elements.
