Ensure links are distinguished by more than just color

There are two ways to comply with this requirement:

1. You can make links appear differently from regular text without relying on color alone. For example, you can add an underline to your links. This makes links easy to identify, even to people who cannot see color at all.
2. You can make links a color which is very different from the surrounding text (a 3:1 ratio), AND ensure that when the link is selected with the keyboard or mouse that it appears
   differently from regular text without relying on color alone.

Unless you have disabled the outline CSS style, links will automatically appear visually distinct when selected with the keyboard.
