Definition and Usage

The margin property sets the margins for an element, and is a shorthand property for the following properties:

If the margin property has four values:

  • margin: 10px 5px 15px 20px;
    • top margin is 10px
    • right margin is 5px
    • bottom margin is 15px
    • left margin is 20px

If the margin property has three values:

  • margin: 10px 5px 15px;
    • top margin is 10px
    • right and left margins are 5px
    • bottom margin is 15px

If the margin property has two values:

  • margin: 10px 5px;
    • top and bottom margins are 10px
    • right and left margins are 5px

If the margin property has one value:

  • margin: 10px;
    • all four margins are 10px

Note: Negative values are allowed.

Default value: 0

Property Values

Value Description Play it
length Specifies a margin in px, pt, cm, etc. Default value is 0. Negative values are allowed. Read about length units Play it »
% Specifies a margin in percent of the width of the containing element Play it »
auto The browser calculates a margin Play it »
initial Sets this property to its default value. Read about initial Play it »
inherit Inherits this property from its parent element. Read about inherit

Margin Collapse

Top and bottom margins of elements are sometimes collapsed into a single margin that is equal to the largest of the two margins.

This does not happen on horizontal (left and right) margins! Only vertical (top and bottom) margins!

Look at the following example:


p.a {
    margin: 30px 0;

p.b {
    margin: 20px 0;
Try it Yourself »

In the example above, the <p class="a"> element has a top and bottom margin of 30px. The <p class="b"> element has a top and bottom margin of 20px.

This means that the vertical margin between <p class="a"> and <p class="b"> should be 50px (30px + 20px). But due to margin collapse, the actual margin ends up being 30px!
