 ====== CSS (Cascading Style Sheets) ======
 This page is for things that I commonly forget regarding CSS.
+===== multiple classes =====
+An HTML entity can have more than one class if the class names are separated by a space.  ID selectors on the other hand can only be one.
+<code>
+<p class="urgent warning">When handling plutonium, care must be taken to avoid the formation of a critical mass.</p>
+</code>
+If you want to define a specific css style that only pertains to items having both class names, you can do this:
+<code>
+.warning.urgent{background: silver;}
+</code>
 ===== adjacent sibling selector =====
