Just some CSS snippets and tricks to help you along the way to becoming a CSS guru.
FONT – REM
Make the root font size 62.5% so that it the same as 10px (not 16 as is the default).
html { font-size: 62.5%; } body { font-size: 14px; font-size: 1.4rem; } /* =14px */ h1 { font-size: 24px; font-size: 2.4rem; } /* =24px */
