SKELETON SCREEN CSS

Zero dependencies, framework agnostic, a minimalistic set of skeleton screen elements consisting of pure css. Includes scss source, minified and non-minified compiled css files with browser vendor prefixes.

What is it:

A skeleton screen is a visual placeholder that appears before the page content renders completely. It provides a low-fidelity preview of the fully rendered page in order to give the impression of a faster load time. A skeleton screen comprises lightly colored shapes, lines, and text that outline the structure of the page before the final content loads in its place.

See example

How to install:

with npm

npm i skeleton-screen-css --save

or yarn

yarn add skeleton-screen-css

or you can download the archive with the project and manually transfer the necessary files to your project folder.

Included files:

• index.scss - source code with default variables;
• index.css - non-minified compiled css with browsers vendor prefixes;
• index.min.css - minified compiled css with browsers vendor prefixes (default with importing via modules);

How to use:

<link rel="stylesheet" href="index.min.css" />

Via webpack, rollup, parcel or any other bundler:
