toshudhiman Graham Sir u r nt understanding what i wnt to say.

I said i had made a css in CSS option on page in mobile version of site.

I can use this css in every new block im making.
But can't able to use the css i had made in the blocks which i had already made (means older blocks)

When i edit them and see the option "class".

I will nt get my css there which i made.
