Week 3 Notes

📌  IMPORTANT NOTE

The Box Model has 4 layers (from inside to outside):

1. CONTENT — the actual text or image inside the element.

2. PADDING — space between the content and the border (inside the box, same background colour).

3. BORDER — a line around the padding.

4. MARGIN — space outside the border (between this element and its neighbours — transparent).

CSS Box Model Properties

/* Box Model Example */

.card {

  width: 300px;              /* Content width */
