? jQuery Element Selectors

? Quick Overview

jQuery element selectors allow you to select HTML elements based on their tag names such as p, div, span, ul, etc. Once selected, you can apply styles, events, animations, or manipulate content easily.

? Key Concepts

Select elements using HTML tag names
Apply operations to all matched elements automatically
Works similarly to CSS element selectors
Core part of jQuery DOM manipulation
Can be combined to select multiple types at once

? Syntax / Theory

The basic syntax for element selectors in jQuery is:

$("element") — selects all matching elements of that type.

➕ Grouping Selectors

You can also select multiple distinct elements at the same time by separating them with a comma:

$("h1, div, p") — selects all h1, div, and p elements.

? Code Example(s)

? View Code Example

// Select all paragraph elements and change text color
$("p").css("color","blue");

? View Code Example

// Hide all div elements on button click
$("button").click(function(){
$("div").hide();
});

? View Code Example

// Select multiple elements using group selector
$("h2, p, span").css("background-color","yellow");

? Live Output / Explanation

In the first example, all  elements become blue instantly. In the second example, clicking the button hides all <div> elements on the page.
