Using CSS3 transforms and calc() in Internet Explorer Posted on
Although CSS calc sizes are supported in Internet Explorer 10 and above, they do not work when used in transform attributes. For instance, transform: translate(0, calc(100% - 10px)); does not work in Internet Explorer.
To work around this, you can chain transforms. For instance, the following statements are equivalent:
transform: translate(0, calc(100% - 10px)); //Does not work in IE
transform: translate(0, 100%) translate(0, -10px); //Works in IE
It’s that simple!
