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.
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".
