Lesson 36 - Module 4: Box Model & Layout

Box-Sizing Magic 🎩

Make box sizing way easier with border-box!

The Sizing Problem

Normally, padding and borders ADD to your width. That's confusing!

Width: 200px

+ Padding: 40px (20px × 2)

+ Border: 10px (5px × 2)

= Total: 250px 😵

You set width to 200px but got 250px!

The Confusion:

When you say "width: 200px", that's JUST the content. Padding and border are extra!
