A reader wrote in to tell me we should update our articles about SVG
elements. The attribute we always use for them,
xlink:href, is deprecated. Indeed, MDN says
I like it. But does it actually work? Lemme fork my little old demo and change all the references. In a quick run through of what I have easy access to:
|Chrome 67||Firefox 61||Safari 11||Edge 17||IE 11||iOS 11|
Better than I thought! But enough 🙅♂️ no-go’s there that up and switching everything seems far too dangerous, especially when
xlink:href has support across the board.
Will browsers actually pull support? I’ll bet ya fifty bucks none of them ever do. There are tons of websites that use the attribute in the old format that will never update, and we know that browsers take breaking old sites very seriously (yay).
It feels like the same thing with, for example,
::before is the new and more correct syntax. But no browser will ever pull support for
:before (I’ll bet ya another 50 bucks) because it just needlessly breaks sites. And because of that, it almost makes the most sense to keep using
:before as you get the widest swath of support that way.
I probably won’t be updating older articles using
unless something bizarre happens and some browser actually does pull support.
