Purpose:
- The primary purpose of the no-js class is to allow the use of CSS to style JavaScript-free pages, i.e. defining CSS styles for JavaScript-enabled browsers as well as for JavaScript-disabled browsers.
- Thus, the “no-js” class will only be present if JavaScript has been disabled. This enables styling a pure HTML and CSS page without the use of any client side-scripting.
- But if JavaScript is enabled, it removes the “no-js” class automatically.
- The “no-js” class is available in the markup by default.
- The “no-js” class is basically a way to be able to style things with or without using JavaScript.
- The “no-js” class is added to the topmost html element which serves as an instruction for Modernizr.
Syntax:
