I put in header.php some .css files to use new icons fonts. But when I update the theme, I lost all configs of fonts.
How can I put this css and update theme normally, without lost configs?
Thanks a lot
To prevent losing changes made in header PHP we suggest you set up a child theme and copy header.php to this folder. Then do your changes there and don’t worry about parent theme updates since you will not remove/replace your child theme files.
