ui: improve styling of links

[tiborsimko]

Current behaviour

The styling of links on the CERN Open Data portal seems to have changed recently (perhaps as part of the home page web accessibility changes?) towards using darker blue for links, which for me makes the links hard to distinguish from the regular text. For example, see:

The dark blue of links here is very close to the black of text.

When I hover over the link, the text becomes a lighter blue shade:

With my older eyes, I find the latter to be much more visible than the former 😅

(IIRC such a lighter shade of blue used to be the link default before the recent web accessibility changes?)

Expected behaviour

The links should be more easily distinguishable visually from the regular text.

Perhaps we could investigate changing the link colour shade, perhaps introduce some link decoration such as underlines, etc?

Changing the color of the hrefs is a great idea, it makes it much easier to spot. I assume it looked something like this before:

To improve the visibility without distracting too much, we could slightly increase the font weight or underline it. Though I am not sure if that looks good on all records or if it makes the page too inconsistent. Do you have other ideas in mind?
