CSS Preprocessor
CSS Preprocessors are tools that extend the functionality of vanilla CSS by adding a wide variety of logical syntax such as you might see in a normal programming language. A browser can only understand CSS, which at times may not be enough to write clean and reusable rules.
A few of most popular CSS preprocessors:
- Sass
- LESS
- Stylus
- PostCSS
.circle {
border: 1px solid #ccc;
border-radius: 50px;
overflow: hidden;
}
.avatar {
@extend .circle;
}
.circle {
border: 1px solid #ccc;
border-radius: 50px;
overflow: hidden;
}
.avatar:extend(.circle) {}
CSS Sprites
CSS Sprites are a means of combining multiple images into a single image file for use on a website. Using the image sprites instead of separate images will significantly reduce the number of HTTP requests a browser makes to the server, which can be very effective for improving the loading time of web pages and overall site performance.
