CSS 👉🏼 I don't know why ::before and ::after are included in the "box-sizing: border-box" reset

Pedro García · 2025-06-07T11:02:47.543Z

I know that `box-sizing: border-box` makes our lifes a lot easier. I've always just used the `*` selector, but: ```css *, *::before, *::after { box-sizing: border-box; } ``` Why `*::before` and `*::after`?

I know that

box-sizing: border-box

box-sizing: border-box

makes our lifes a lot easier. I've always just used the

selector, but:

*,
*::before,
*::after {
  box-sizing: border-box;
}

*,
*::before,
*::after {
  box-sizing: border-box;
}

Why

*::before

*::before

and

*::after

*::after
