+What was once a bug is now a widely used CSS property. It basically means you can choose whether or not to include borders and padding in the width of your content.

+Without box-sizing: border-box

+
+With Box Model
+With box-sizing: border-box
+Borders and padding are drawn inside the set width of your content. The margin is drawn outside.
