Categories: jQuery Extensions | Basic Filter
jQuery(':header')
Description: Selects all elements that are headers, like h1, h2, h3 and so on.

jQuery(':header')
version added: 1.0
Note:
Because:header
is a jQuery extension and not part of the CSS specification, queries using :header
cannot take advantage of the performance boost provided by the native DOM querySelectorAll()
method. To achieve the best performance when using :header
to select elements, first select the elements using a pure CSS selector, then use .filter(":header")
.
-
Adds a background and text color to all the headers on the page.
HTML:
<h1>Header 1</h1> <p>Contents 1</p> <h2>Header 2</h2> <p>Contents 2</p>
CSS:
body { font-size: 10px; font-family: Arial; } h1, h2 { margin: 3px 0; }
Code:
$(":header").css({ background:'#CCC', color:'blue' });
