Hello,

Try using this guide to creating a child theme. After you create a child theme for the Modern theme, just place all changed files in the child theme. If Modern theme gets updated, your child theme won't.

Ok but i can not upgrade olso osclass because it gives me an error in the current thema.
I tried modifying on the localhost.
If I make installation on subdomain whit oscalss and the current theme modern and I start working to change to be the same.
It will take some time I believe.

Question:
If I have a subdomain and I work there it will not affect my current web in indexing and google or current SSL.
