Best Utility Chrome Extensions for Web Designers

#1 JavaScript and CSS Code Beautifier

If you have ever opened a minified JQuery or Bootstrap document, you know how hard it is to read them. Sometimes we come across such web documents because designers remove the extra spaces and intending in documents, which are essential for readability, at the end of the work to optimize the web page rendering.

It is really difficult to read such documents. Fortunately, we can now add intending, necessary space and line breaks in such JavaScript and CSS documents, including minified, with a click of a button; thanks to the JavaScript and CSS Code Beautifier.

What you can do.

  • Improve the readability HTML and CSS documents in the Chrome browser by adding intending and necessary line breaks

How to do that.

  • Install the extension
  • Open a document with poor readability
  • Click “Beautify” button on the pop-up bar below the title bar

This tool is really helpful when you open documents via the “View Page Source” option.
