== Why is this an issue? ``++calc++`` is a CSS3 function that provides the possibility to do simple math in CSS (add, subtract, divide, multiply). Without spaces around operators, ``++calc++`` will have no effect. More precisely, before an operator, there must be a single whitespace or a newline plus indentation. After an operator, there must be a single whitespace or a newline. === Noncompliant code example [source,css] ---- #div1 { position: absolute; width: calc(100%- 100px); /* Noncompliant; no space after the % sign */ } ---- === Compliant solution [source,css] ---- #div1 { position: absolute; width: calc(100% - 100px); } ---- ifdef::env-github,rspecator-view[] ''' == Implementation Specification (visible only on this page) === Message Add spaces around this operator.
