 ## Description
 <section id='description'>
 When using your variable as a CSS property value, you can attach a fallback value that your browser will revert to if the given variable is invalid.
-<strong>Note:</strong> This fallback is not used to increase browser compatibilty, and it will not work on IE browsers. Rather, it is used so that the browser has a color to display if it cannot find your variable.
+<strong>Note:</strong> This fallback is not used to increase browser compatibility, and it will not work on IE browsers. Rather, it is used so that the browser has a color to display if it cannot find your variable.
 Here's how you do it:
 <blockquote>background: var(--penguin-skin, black);</blockquote>
 This will set background to black if your variable wasn't set.
