CSS Margins: What Is the Shorthand Property for Margins?

Margins in CSS control the space outside an element’s border, separating it from surrounding elements. While CSS allows you to set margins individually (margin-top, margin-right, margin-bottom, margin-left), there’s a faster and more efficient way to write them.

👉 That’s where the margin shorthand property comes in.

✅ What Is the Shorthand Property for Margins?

The shorthand property for setting all four margins at once is simply:

margin

This lets you define top, right, bottom, and left margins in a single line of code.

✅ Syntax of margin Shorthand

margin: [top] [right] [bottom] [left];

The number of values you provide determines how the margins are applied:

📌 One Value

margin: 20px;

• Applies 20px to all four sides.

---

📌 Two Values

margin: 10px 20px;

• 10px is top and bottom
• 20px is left and right

---

📌 Three Values

margin: 10px 15px 20px;

• 10px is top
• 15px is left and right
• 20px is bottom

---

📌 Four Values

margin: 10px 15px 20px 25px;

• Top: 10px
• Right: 15px
• Bottom: 20px
• Left: 25px

🔁 The order is always: Top → Right → Bottom → Left (TRBL, like “trouble”)

---

✅ Example

.box {
  margin: 10px 20px;
}

This sets:

• 10px on top and bottom
• 20px on left and right

---

✅ Auto Margin for Centering

A common trick is:

margin: 0 auto;

• Top & bottom margin: 0
• Left & right margin: auto
  👉 This centers a block element horizontally inside its parent (when a width is set).
