Nested links are illegal.
Meaning, you can’t have a link sitting inside a block level link. And of course, this makes sense. But, if you’re a fan of block level links, like myself, then you’ve certainly experienced times when you’ve wanted to nest a link.
For example, say you have a blog / content site with a post pattern that features an article link wrapping all the content – image, title, excerpt, etc.
But then, inside that block level link, you’d like to also include the post’s taxonomy, with a link to its archive. No go.
You’d have to either link each item separately (weak), or open, close, and then open the post link again (equally weak).
