> 1. ... if we could improve on the method described in the specs regarding the calculation ... This actually seems to be the most feasible idea to me. We just need to add a new anchor value, e.g.: `anchor(center-align)` which automatically unfolds into `min(abs(0% - anchor(center)), abs(100% - anchor(center)))` then we can achieve centering with two lines of CSS ```css inset-inline: anchor(center-align); justify-self: center; /* The proper way to do centering in positioned layout, but lacking browser support */ margin-inline: auto; /* Fallback if the browser doesn't support it */ ``` > 2. Allow using the dimensions of the element itself somehow when anchoring. `anchor-size(self-width)` doesn't look compatible with the current design, where `anchor-size()` needs to be treated as a regular `<length>`, can participate in `calc()` and must be evaluated into a pixel value before laying out the element. To make it compatible, it has to be a new keyword value, something like `width: self-anchor-width`, but then it can't participate in any `calc()` any more. > 3. ... what if we could have something like a `inset-center` or something ... That's an interesting idea. It's also more general than anchor positioning that it should go to the CSS Positioned Layout module instead. -- GitHub Notification of comment by xiaochengh Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/8979#issuecomment-1615073641 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
