Colored Links
Colored link helpers tint a link with a theme colour, including hover and focus states, while the link opacity, offset and underline helpers fine-tune how the text and its underline look. Combine them for footers, inline copy, navigation and table actions.
1All link colours
link-* classes for every theme colour, plus link-body-emphasis for high contrast text.
