Using ID and Class Selectors in jQuery

Element Selector

The element selector targets HTML elements based on their tag name.

$("p")

This selects all <p> elements on the page.

ID Selector

The ID selector targets an element with a specific ID attribute.

$("#myElement")

This selects the element with id="myElement".

Class Selector

The class selector targets elements with a specific class attribute.

$(".myClass")

This selects all elements with class="myClass".
