CSS Optimization
CSS optimization involves techniques to reduce file size and improve page load speed.
CSS Optimization
Optimizing CSS is crucial for website performance. Smaller CSS files load faster, improving the user experience.
1. Minification
Minification removes unnecessary characters (whitespace, comments, newlines) from the code without changing its functionality.
Original:
body {
background-color: white;
color: black;
}
Minified:
body{background-color:white;color:black;}
2. Use Shorthand Properties
Using shorthand properties reduces the amount of code.
Instead of:
margin-top: 10px;
margin-right: 20px;
margin-bottom: 10px;
margin-left: 20px;
Use:
margin: 10px 20px;
3. Avoid @import
Using @import prevents stylesheets from being downloaded in parallel, slowing down page load. Use <link> instead.
4. Remove Unused CSS
Delete styles that are no longer used in your HTML to keep the file size small.
