blocks and inline elements

[sara_jessica]

hi, i 'm learning html recently and i've taught that inline elments can't hold block elements (flow content), but when i tried a <div> tag nested in <a> tag , in w3c validator didn't recognize it like in error, why?

HTML started allowing nesting blocks inside <a> elements when it transitioned to version 5 because there are so many use cases for hyperlink blocks.

I still just set the display of <a> elements to "block" with CSS to avoid an unnecessary <div> inside it unless the structure is complicated.
