Nicky Meuleman, inspired by Cassie Evans, details how they built the anchor link hover on their sites. When a link is hovered, another color underline kinda slides in with a gap between the two. Typical text-decoration doesn’t help here, so multiple backgrounds are used instead, and fortunately, it works with text that breaks across multiple lines as well.
