This was not a HTML snippet by itself, but I remember early 2000s almost every website had three small icons somewhere: Set as homepage, Add to favorites, Contact (an envelope/email icon). I think I never used them (I didn't use Favorites back then, don't know why), but it was nice to see that they were available.
