Explainerhttps://jakearchibald.com/2021/dom-cross-fade/ Specification https://drafts.fxtf.org/compositing-2/#porterduffcompositingoperators_plus_lighter Summary This proposal adds a plus-lighter value to the mix-blend-mode property. Plus-lighter adds the source and destination colors multiplied by their respective alphas. This operation is useful when cross fading between two elements that may contain common pixels. In that case, plus-lighter ensures that the common pixels do not change in appearance as opacity changes from 0 to 1 on one element and from 1 to 0 on the other.
