re: Yup, ..to be extra safe :D html { box-sizing: border-box; } *, *:before, *:after { box-sizing: inherit; }

I think that using box-sizing: inherit;’ can be bad. If you do this, and decide to change box-sizing on an element, all of that elements children will also have their box-sizing changed.

Unless you are sure you want that to happen, it’s probably best just to use ‘box-sizing: border-box;’ to ensure that all elements use ‘border-box’. If any elements need a different box-sizing, you would override it with more specificity.

Yeah indeed, things can get messy in this case.

I was a box-sizing: inherit; person, then I realised this is super useful:

.page-restrictor {
  max-width: 1200px;
  margin: 0 auto;
  padding: 0 20px;
  box-sizing: content-box;

It means that when the screen is less than 1240px wide, it will have a 20px gap down either side of the screen with no need for media queries.

This technique doesn't work with box-sizing: inherit; though.
