Minify JavaScript, and CSS in Blogger in 2021

Blogger Page Speed

Hi, while auditing your blogger in Google page speed tool, have you ever noticed opportunities to make your blogger’s loading speed fast. These are, “minify CSS” and “minify JavaScript. Google page speed tool shows the lists of all unminified CSS files and JavaScript along with the potential saving in kilobytes (KB) when these files will minified. In this article you will come to know what are unminified CSS and JavaScript and how to Minify these files in Blogger.

WHAT ARE UNMINIFIED CSS AND JAVASCRIPT

When CSS JavaScript files contain unnecessary characters, such as comments, whitespace, and indention, then these files are unminified. However these unminified files can be less complicated, easy to read and edit.

UNDERSTANDING MINIFICATION PROCESS

Comments, whitespaces, and indention can be safely removed to reduce file size without affecting the core functionality of CSS and JavaScript and how browser processes the styles. This process is minification.

According to Google, Minification can improve the byte efficiency and the loading speed by removing all unwanted characters.

MINIFICATION OF AN UNMINIFIED CSS

Take a look at the following CSS block.


body {
  font-family: “Benton Sans”, Helvetica Neue”, helvetica, arial, sans-serif;
  margin: 2em;
}

/* all titles need to have the same font, color and background */
h1 {
  font-style: italic;
  color: #373fff;
  background-color: #000000;
}

h2 {
  font-style: italic;
  color: #373fff;
  background-color: #000000;
}

This content can be easy to read but it’s a large file than necessary.

  • It uses spaces for indentation purposes and contains comments, which are ignored by the browser, so they can be removed.
  • The <h1> and <h2> elements have the same styles: instead of declaring them separately: “h1 {...} h2 {...}” they could be expressed as “h1, h2{...}“.
  • The background-color, #000000 could be expressed as just #000.

After making some of these changes you could get a more compact version of the same style.


body{font-family:“Benton Sans”,“Helvetica Neue”,helvetica,arial,sans-serif;margin:2em}h1,h2{font-style:italic;color:#373fff;background-color:#000}

    1. Hi saurabh, I have checked your website in Google page speed tool. Congratulation, your website doesn’t have any unminified JavaScript or CSS. You don’t have to worry about this. If you’ll minify your all html codes, they can be a little complex for you to edit. However while checking your website I seen so many render-blocking resources and unused JavaScript. I recommend you to remove render-blocking resources and unused JavaScript. Use images in WebP format. You can do this all by reading my other articles.
