Add following text decoration styling to theme Links

Please add the following to the theme’s links styling so that we don’t have to keep writing custom css making sure that we are applying it to every possible link ‘type’ (e.g. post-content, brxe-text etc.):

  • line style
  • line colour
  • line thickness
  • line offset

It would also be good to allow us to define classes and attributes where this styling is not to be applied.
