Hello
Have you tried activating: https://docs.litespeedtech.com/lscache/lscwp/pageopt/#css-per-url ?
You need to connect to Quic.Cloud for this feature to work. No money required, just request a domain key: https://docs.litespeedtech.com/lscache/lscwp/general/

ok I linked it to there at Quic.Cloud . But now seeing another problem is that.. The site size getting bigger always in size ? It was only 400MB. all of a sudden I see it is 1.24GB ? Why is that ? And what to do ?

for size you can read here: https://docs.litespeedtech.com/lscache/lscwp/ts-optimize/#disk-space-filling-fast this is what has increased your site size and image optimization(if you run it).
