I am having this exact issue with a Magento 2 compilation. Did you find a hack or fix to use CSS variables in your less files? @ddetyuk
from less.php.
This matches the behaviour of the official Less.js 2.x parser. Try in this demo for example.
The error happens because calc()
is treated here as a Less compilation function, instead of as a CSS value to preserve for the browser to process instead. You can make this work by using Less escaping, like so:
.a {
animation-iteration-count: ~"calc(var(--css-variable) * 2)";
}
In Less.js 3.0, the compiler was improved to recognise var()
syntax and pass it through to the browser. However, we don't yet support most of the Less.js 3.x syntax in Less.php.
from less.php.
