Steps to reproduce

Currently calc() is supported as a CSS mathematical function. The CSS Values and Units Level 4 Specification describes a list of math functions 1 consisting of calc() in addition to min() and max(). Suggest implementing recent specification changes.

The motivation for opening this bug is the reference to the aforementioned mathematical functions in the HTML Standard [2], which supports the appearance of mathematical functions in the sizes attribute on <img> elements.

    • Thanks for the report! This seems like a feature request, but we will keep this in mind in the future. I’d recommend using the uservoice for better impact, though.
