Hi,
After loading the font, you don't need to change in its CSS file like you mentioned: /templates/ja_brickstore/fonts/cyrilicold/css
Now to use the font you added, open the file: root//templates/ja_brickstore/less/variables.less
Look for this declaration:
@font-family-sans-serif: "Karla", sans-serif;
@font-family-serif: Georgia, "Times New Roman", Times, serif;
@font-family-monospace: monospace;
@font-family-cursive: "Unica One", cursive;
@font-family-base: @font-family-sans-serif;
Here you can create a new variable for the new font and set it as font-family-base (like font-family-sans-serif in above code).
Once done, you go to backend of your site > Extenisons > Templates > JA Brickstore > compile less to css to see the changes (REMEMBER to backup all current CSS files first as when compiling less to css, they will be overwritten).
Regards
