4. Avoid @import
@import use karne se CSS loading delay hoti hai.
Better hai ki external CSS ko <link> tag se load karo:
5. Use Shorthand Properties
Shorthand properties use karo, ye space bachata hai aur fast parse hota hai.

6. Cut Down Unnecessary Animations
Zyada animations performance ko slow kar dete hain. Sirf necessary animations use karo.
7. Use Efficient Animation Properties
Kuch properties jaise width, height, left, top animation me use karne se layout recalculation hota hai (slow).
Better hai ye use karo:
- transform
- opacity
- filter
8. Combine and Minify CSS
Ek hi CSS file use karo aur unnecessary spaces/comments hatao taaki file size kam ho.
Tools:
- CSS Minifier
- PostCSS
- Online compressors
9. Cache Your CSS
Browser caching enable karo taaki CSS baar-baar load na karna pade.
