I'm looking at /lib/web/css/source/lib/variables/_typography.less
I was able to add a new @font-family__oswald to my own _theme.less.
Now, I'm trying to edit the h1 tags to make it all uppercase but I can't seem to get it to work. I've placed it in my _theme.less and I also tried creating a _variables_extend.less and import it into my _extend.less file like the Magento documentation.
This is what I've added:
@heading__text-transform__base: uppercase;
@h1__text-transform: @heading__text-transform__base;
I've also deleted the var folder and pub/static/frontend folder. Cleared cache as well.
What am I doing wrong?
