CSS Class Selector

  • Difficulty Level : Basic
  • Last Updated : 11 Oct, 2021

The .class selector is used to select all elements which belong to a particular class attribute. In order to select the elements with a particular class, use the period (.) character specifying the class name ie., it will match the HTML element based on the contents of their class attribute. The class name is mostly used to set the CSS property to a given class.

Syntax: 

.class {
    // CSS property
}
