.font-size-1
: This sets the font size to a smaller scale..font-size-2
: This sets the font size to a small scale..font-size-3
: This sets the font size to a medium scale..font-size-4
: This sets the font size to a large scale..font-size-5
: This sets the font size to a larger scale..font-size-6
: This sets the font size to the largest scale.
