- et
- Combine multiple images into one sprite: By combining all the icons into a single sprite image, we reduced the number of HTTP requests and improved page load times.
- Specify image positions using CSS: With CSS sprites, we used the background-position property to display specific parts of the combined image without separate files.
- Use CSS to display different parts of the sprite: By adjusting the background-position property, we were able to switch between different parts of the sprite for hover effects or dynamic display changes.

- Adopt a mobile-first approach: Begin with CSS styling for mobile devices and then enhance the design for larger screens. This approach ensures optimization for mobile browsing, which is increasingly prevalent.
- Ensure flexible typography: Utilize CSS rules that enable typography to scale and adjust based on the screen size. Utilize relative units such as “em” or “rem” for font sizes to adapt the text to various devices. CSS frameworks can provide styles that are specifically designed for responsive typography.
- Minimize CSS file size: To reduce file size, remove unnecessary whitespace, comments, and unused styles. This will optimize loading time.
- Combine CSS files: Instead of having multiple CSS files, combine them into one. This reduces the number of HTTP requests and improves page load times.
