+<p>To perform calculations when specifying a CSS property <code>calc()</code> function can be used. This function takes single expression as
+parameter. When writing this expression some rules must be respected:</p>
+<ul>
+  <li> no empty <code>calc()</code> </li>
+  <li> there should be an operator between the arguments, spacing should be respected </li>
+  <li> there should not be any division by zero </li>
+  <li> the resolved type should be valid for where the expression is placed </li>
+</ul>
+<p>Otherwise <code>calc()</code> function will be invalid and the entire rule using it will be ignored.</p>
+<h2>Noncompliant Code Example</h2>
+<pre>
+.btn {
+  border: solid black 1px;
+  width: calc(100% 80px);  /* Noncompliant */

+.btn {
+  border: solid black 1px;
+  width: calc(100% - 80px);
