To increase icon sizes relative to their container, use attribute size with value
lg (33% increase), 2x, 3x, 4x, 5x, 6x, 7x, 8x or 9x.

And if you build this {docfile} with another backend than bootstrap, don’t forget to set the width attribute with value 20 for lg, 28 for 2x, 42 for 3x, 56 for 4x, 70 for 5x, 84 for 6x, 98 for 7x, 112 for 8x or 126 for 9x.
