Dear experts

What is difference between

#header
div#header

Thanks

[Wickham]

#header is an id name that can be used with any element like these markups:-

<h3 id="header">...</h3>
<div id="header">...</div>
<ul id="header">...</ul>
<table id="header">...</table>

(except that you should only use an id once on a page).

div#header can only be used in a div markup:-

<div id="header">...</div>

(but only use it once on a page).
