Cascade leaves in style bring life to the web. CSS controls the apartment of HTML elements such as colors, fonts, layouts and animations. CSS, however, can quickly become a braided network of inflated and outdated styles and reducing the rules. The result is often a slower load time and complicated disorders.
Optimization of Fils CSS avoids these snapus.
Verification of CSS
Start by verifying the status of your CSS files.
- Browser tools. Open the site in Chrome or Firefox, right -click the page and select “Check”. Filter the “CSS” on the “Network” tab to see the size and time of the styles.
Pagespeed Insights identified speed optimization, such as this example for unused CSS.
Other tools can simplify the cleaning process.
- NejedCSS is a user -friendly tool that searches your site, identified unused CSS, and generated in a simplified version. Enter your URL and let the tool make a heavy lifting.
- Cleancss offers online CSS minifs and optimizer. It pulls out unnecessary spaces and comments and removes the reduction code, resulting in a slimmer styles template.
- CSS LINT does not directly remove unused CSS; It emphasizes inefficient and potential mistakes. Use it to determine where your CSS can be effective and improved.
For example, these unused styles for the old banner should be removed:
.banner { background: #f4f4f4; padding: 20px; }
.banner__title { font-size: 2em; }
Active styles remain:
.header { background: #fff; padding: 10px; }
.header__logo { height: 50px; }
Optimization of CSS
Once you have removed the unused code, the next step is to optimize what is left. Here are my go-to tactics.
- Minification removes unnecessary characters (eg gaps and comments) from your CSS and reduces the file size without the affitation function. Minify.org is my best tool.
- Multiple combined CSS files into one. Less HTTP requirements means quick loading times. However, if critical CSS is necessary immediately and uncritical CSS can be loaded later, consider them strategically divided.
- To accept the name of the Convention. Structured naming, such as BEM, helps avoid conflicts and redundancy and makes it easier and easier to optimize your CSS.

.container {
padding: 10px;
font-size: 16px;
background-color: #f0f0f0;
}
/* Styles for tablets and larger screens */
@media (min-width: 768px) {
.container {
padding: 20px;
font-size: 18px;
background-color: #e0e0e0;
}
}
/* Styles for desktops */
@media (min-width: 769px) {
.container {
padding: 30px;
font-size: 20px;
background-color: #d0d0d0;
}
}
