How to build UI

Spacing

• Default spacing should be the font-size, 16px here.
• If you want to add spacing to an element you should use a multiplier of @spacing, @spacing * 2, @spacing / 2
• For symmetrical spacing (both top/bottom or left/right) you should use padding (padding: @spacing 0)
• Always push down UI elements with a margin-bottom, it will make them fit coherently in a layout. If you want to customize the margin-bottom in the html template with the utility classes: u-mb1, u-mb2

Colors

• Don't create a color that is too close to another one
• Ban light grays, it has very low contrast and readability

Other

• Use pseudo-elements when you can so that you can toggle it with CSS classes (example: is-required)
• When you need a special case of a CSS element, either generalize it with a modifier class or create a utility class (reference: http://www.basscss.com/)
