If i have a css-code
<style>
width: 100%;
	width: -webkit-calc( 100% - 30px );
	width: -moz-calc( 100% - 30px );
	width: calc( 100% - 30px );
</style>
Then web page https://validator.w3.org/ shows errors:
Error: CSS: width: Parse Error.
At line 285, column 36
c( 100% - 30px );
Maybe the web page have to repair?
Thank you
