• Add minimum space between tabs (5px)
• Add space on the left and right sides of the tabs block.

Besides, active tab should have font-weight:700 but the tab shouldn't change it's size, it would be only the text included within it when going from defaults state to an active one (see pen as reference: https://codepen.io/eZ_UI/pen/Gmdqxr)
