CSS Margins

CSS margins are used to create space around HTML elements, outside of their borders. They allow you to control spacing between elements, improving layout and readability.

Margin Property

The margin property sets the space outside an element. It can take values in pixels, percentages, em units, or auto.

Example

<!DOCTYPE html>
<html>
<head>
<style>
div {
  margin: 60px;
  border:1px solid red;
}
</style>
</head>
<body>

<div>This is my first CSS page.</div>

</body>
</html>

Individual Margins

You can set margins for each side of an element individually using: margin-top, margin-right, margin-bottom, and margin-left.

Example

<!DOCTYPE html>
<html>
<head>
<style>
div {
  margin-top: 100px;
  margin-right: 70px;
  margin-bottom: 50px;
  margin-left: 70px;
  border:1px solid red;
}
</style>
</head>
<body>

<div>This is my first CSS page.</div>

</body>
</html>

Shorthand Margin Property

You can use the shorthand margin property to set all four sides in one line:

Example

<!DOCTYPE html>
<html>
<head>
<style>
/* top right bottom left */
div {
  margin: 10px 15px 20px 25px;
}
</style>
</head>
<body>

<div>This is my first CSS page.</div>

</body>
</html>

Try this code

/* top right & left bottom  */     
div {
  margin: 10px 20px 15px;
}

/* top & bottom, left & right */
div {
  margin: 10px 20px;
}

/* all sides same */
div {
  margin: 15px;
}

Auto Margin

Setting margin: auto; can be used to center block-level elements horizontally.

Example

<!DOCTYPE html>
<html>
<head>
<style>
div.centered {
  width: 50%;
  margin:auto;
}
</style>
</head>
<body>

<div class="centered">This is my first CSS page.</div>

</body>
</html>

Try this code

Negative Margin

Margins can also be negative, allowing elements to overlap or move closer than normal spacing.

Example

<!DOCTYPE html>
<html>
<head>
<style>
div {
  margin-top: -10px;
}
</style>
</head>
<body>

<div>This is my first CSS page.</div>

</body>
</html>

Prefer shorthand margin when possible
Use auto margins to center content horizontally

Common Mistakes with Margins
