+<p><code>linear-gradient</code> was standardized with CSS3. Before that, it was possible to use different non-standard values to define the gradient's
+direction. Because these values are not standard, they are not supported in all browsers and therefore they should no longer be used in order to get
+the expected gradient in the latest browser versions that support CSS3.</p>
+<p>This rule raises an issue when the first parameter of a <code>linear-gradient</code> is not a valid <code>&lt;side-or-corner&gt;</code> or
+<code>angle</code>.</p>
+<h2>Noncompliant Code Example</h2>
+<pre>
+.foo {
+  background: linear-gradient(top, #fff, #000);
+}
+
+.bar {
+  background: linear-gradient(45, #fff, #000);
+}
+</pre>
+<h2>Compliant Solution</h2>
+<pre>
+.foo {
+  background: linear-gradient(to top, #fff, #000);
+}
+
+.bar {
+  background: linear-gradient(45deg, #fff, #000);
+}
+</pre>
