Answer 1

So you can replace http://olddomain.comwith https://olddomain.comin all css files in the current and subdirectories:

find . -name "*.css" -exec sed -i 's|http://olddomain.com|https://olddomain.com|g' {} \;

The command must be run from the theme directory. Replace olddomain.com with your domain. And just in case, before doing it, make a backup of the files.

Answer 2

You need to change it in the database, here is the SQL query:

UPDATE wp_posts SET guid = REPLACE (guid, 'http://olddomain.ru', 'https://newdomain.ru');
UPDATE wp_posts SET post_content = REPLACE (post_content, 'http://olddomain.ru','https://newdomain.ru');

In phpMyAdmin, you can insert it here:

Didn't understand the question the first time. If it is written in css, then change it in css.
