Style links properly

[SilvanVerhoeven]

Currently, links are styled differently and not necessarily reasonable. Define and implement a system of how to style links on myHPI. Pay attention to the following:

• The color should fit to the general accent color of the website (e.g. have the same color)
• Notice basic accessibility standards, e.g. make sure that there are either more cues for link than just color or at least make sure links always stand out, even with red-green color blindness
• There are different environments for links → either find a proper solution for all of them or clearly define where which style should be used. Make sure that these different styles are still consistent/intuitive
  • Text
  • Menu
  • Breadcrumbs
  • Table of Contents
  • ...
• What happen when clicking on a link – should the background fill, shoud there be a box around the link, should we color already visited links differently?
