It is a long list of changes to get the icons to be bigger:
1. The dart themes style.css I increased values by 20.
a. line 5 increased to 120.
b. line 18, 25 increased to 78
c. line 33 increased to 74
d. lines 44, 45, 52 and 53 increased to 64
e. lines 63, 68 and 69 increased to 32.
f. line 67 increased to 15
