 Look up the `box-sizing` property, which affects how the total heights and widths of elements are calculated.
 
 - `box-sizing: content-box`: This is the default value of `box-sizing` and adheres to the rules above.
-- `box-sizing: border-box`: The `width` and `height` will include the content, padding and border, but not including the margin. This is a much more intuitive way to think about boxes and hence many CSS frameworks (e.g. Bootstrap, Tailwind, Bulma) set `* { box-sizing: border-box; }` globally, so that all elements use such a box model by default. See the [question on `box-sizing: border-box`](/questions/quiz/what-does-box-sizing-border-box-do-what-are-its-advantages) for more information.

+    padding: 10px;
+    border: 5px solid black;
+  }
