While whinging about the underlines on text, I pointed out that this site's design worked well, but I couldn't quite put my finger on it.
A bunch of folks pointed out a few technical details - that it was a shadow, not an underline, but since it is a different colour than the text it flowed a little better.
We can actually have obvious links without having the text in different colours - what folks felt was very 1990s web 1.0.
In languages with diacritics and bits that hang under the text, it's more obvious that it's one link
Here's a small example:
It looks a lot better, solves one critique people have of the design - since the text stands out less yet is an obvious link
I don't know much CSS (and less of Less), so I don't now if we could change the underline colour for clicked links (which would solve a second), but could we consider this as an alternative way to handle links?
