How can I implement own CSS Code?
I created a new style and tried to add there some new CSS (/styles/ownstyle/css/theme.css), but after using the Customizer, everything is lost.
How and where can I implement my own CSS without losing it after using the Customizer?
Where can I put the path of a new CSS file? How has this path have to look like?
Regards,
Elena

Please never edit our own css files.

Your custom.css goes here:
css/custom.css
or
styles/ownstyle/css/custom.css
