I’ve got a code pen example here: https://codepen.io/soluml/pen/wvZjVmW

Moving the popup works perfectly but I wasn’t able to find a way around positioning the chevron.

Hi! First of all, thanks for reading. I have also wanted something like anchor positioning for a long time so it’s exciting to see browsers shipping support fairly quickly.

On behalf of your question, we will be making entries for each anchor positioning property on the Almanac, so I will try to cover that if possible soon. ;)

One thing I’m still trying to figure out though is how to position a little chevron or arrow on a pop in response to the position try options.

You can’t set custom properties in the position try at rule, so there’s seemingly no way to do it yet.

Still, so incredibly useful!
