I'm experimenting with Bootstrap-3, but cannot find where to change the font sizes. There's a myriad of LESS files and I'm utterly lost in them.
Using the 'Superhero' bootswatch theme, links in my sidebar are considerably smaller than the body text size, and a different font. And, oddly enough, any text placed in <column>s (using columns plugin) is also smaller with links a different colour than in the sidebar! There appears to be no style rule in the columns plugin that stipulates font size.
On the other hand, if I change to the 'Simplex' bootswatch theme, all fonts and colors are consistent between body copy, columns and sidebar.
I can't find in the Forest of Less where to change these rules - I can't see the wood for the trees!
