Css select all element

CSS selectors

The CSS selectors module defines the patterns to select elements to which a set of CSS rules are then applied along with their specificity . The CSS selectors module provides us with more than 60 selectors and five combinators. Other modules provide additional pseudo-class selectors and pseudo-elements.

In CSS, selectors are patterns used to match, or select, the elements you want to style. Selectors are also used in JavaScript to enable selecting the DOM nodes to return as a NodeList .

Selectors, whether used in CSS or JavaScript, enable targeting HTML elements based on their type, attributes, current states, and even position in the DOM. Combinators allow you to be more precise when selecting elements by enabling selecting elements based on their relationship to other elements.

  CSS Selectors

  A CSS selector selects the HTML element(s) you want to style.

  CSS Selectors

  CSS selectors are used to «find» (or select) the HTML elements you want to style.

  We can divide CSS selectors into five categories:

  • Simple selectors (select elements based on name, id, class)
  • Combinator selectors (select elements based on a specific relationship between them)
  • Pseudo-class selectors (select elements based on a certain state)
  • Pseudo-elements selectors (select and style a part of an element)
  • Attribute selectors (select elements based on an attribute or attribute value)

  This page will explain the most basic CSS selectors.

  The CSS element Selector

  The element selector selects HTML elements based on the element name.

  Example

  Here, all

  elements on the page will be center-aligned, with a red text color:

  The CSS id Selector

  The id selector uses the id attribute of an HTML element to select a specific element.

  The id of an element is unique within a page, so the id selector is used to select one unique element!

  To select an element with a specific id, write a hash (#) character, followed by the id of the element.

  Example

  The CSS rule below will be applied to the HTML element with

  Note: An id name cannot start with a number!

  The CSS class Selector

  The class selector selects HTML elements with a specific class attribute.

  To select elements with a specific class, write a period (.) character, followed by the class name.

  Example

  In this example all HTML elements with will be red and center-aligned:

  You can also specify that only specific HTML elements should be affected by a class.

  Example

  In this example only

  elements with will be red and center-aligned:

  HTML elements can also refer to more than one class.

  Example

  In this example the

  element will be styled according to and to

  This paragraph refers to two classes.

  Note: A class name cannot start with a number!

  The CSS Universal Selector

  The universal selector (*) selects all HTML elements on the page.

  Example

  The CSS rule below will affect every HTML element on the page:

  The CSS Grouping Selector

  The grouping selector selects all the HTML elements with the same style definitions.

  Look at the following CSS code (the h1, h2, and p elements have the same style definitions):

  h2 text-align: center;
  color: red;
  >

  p text-align: center;
  color: red;
  >

  It will be better to group the selectors, to minimize the code.

  To group selectors, separate each selector with a comma.

  Example

  In this example we have grouped the selectors from the code above:

  All CSS Simple Selectors

  Selector	Example	Example description
  #id	#firstname	Selects the element with >
  .class	.intro	Selects all elements with >
  element.class	p.intro	Selects only elements with >
  *	*	Selects all elements
  element	p	Selects all elements
  element,element.	div, p	Selects all elements and all elements
