jQuery Element Selectors

Using element selectors in jQuery means you can easily find HTML web page elements without manually finding the elements inside the HTML which can often be like finding a needle in a haystack.

With jQuery element selectors you can manipulate HTML elements and create JavaScript variables from them, assign events to them, animate them, edit them and much more!

The beauty of these special selectors is that a simple jQuery element selector line can find and select several HTML elements all at the same time! Magic.

Here is how you do it:

$("p") //selects all 

elements. $("p.intro") //selects all

elements with. $("p#demo") //selects the first

element with id="demo".
