The lesson about relative measurements in CSS says that if I set the width/height of an element as a percentage, I need to set the width/height of its parent element first. However, in the sample website’s code in the same lesson I could not find a single absolute height/width declaration in the CSS of any parent element whose child elements we had to manipulate using percentage values.

Does anyone know why the code still works on the page?

Many thanks
