I'm doing a fairly straight forward css'rule
#content {
height: ~'calc(100% - 65px)';
}
But it breaks the browser in IE10, literally makes it stop working and demands reboot/refresh. Although this works perfectly in IE9/IE11, Chrome and Firefox that I've tried it in. I'm also using the ~'' to escape the expression so LESS won't remove the spaces.
Does anyone know why this breaks my browser? And also how come it work in IE9 & IE11 and specifically not IE10?
