Can I use calc() with border-width?
I would like the following CSS to work:
border-left-width: calc(10% + 10px);
border-right-width: calc(10% + 20px);
Any <length> value
border-width cannot use a % value as any % is NOT related to size of the element.
So, basically...NO you can't use
calc WITH % for border-width because it doesn't know what it's supposed to be a % of.
