Borders

Border classes are separated into three groups. They are used to draw, color, and style borders.

All border classes start with the fragment border-.

Drawing

These classes will draw transparent borders on the designated sides of the element. Borders are always 1px wide.

Available Classes

All sides: border
Top border: border-top
Bottom border: border-bottom
Left border: border-left
Right border: border-right
Vertical borders (top and bottom): border-vertical
Horizontal borders (left and right): border-horizontal

Note: To keep the naming scheme consistent, “vertical” and “horizontal” refer to the sides of the element on which the borders are applied, not the direction in which they appear to point.

Coloring

The transparent borders from above need to be colored in to be visible (as seen in the previous code examples).

There is a set of colors that you can pick from. In addition to the four signal colors for status reports (confirm, info, etc.), there are some plain colors that are free to use for contrast, focus, or any other application.
