The shape-margin CSS property sets a margin for a CSS shape created using shape-outside.

The margin lets you adjust the distance between the edges of the shape (the float element) and the surrounding content.

Syntax

/* <length> values */
shape-margin: 10px;
shape-margin: 20mm;

/* <percentage> value */
shape-margin: 60%;

/* Global values */
shape-margin: inherit;
shape-margin: initial;
shape-margin: unset;

Values

<length-percentage>
Sets the margin of the shape to a <length> value or to a <percentage> of the width of the element's containing block.

Formal syntax

<length-percentage>

where
<length-percentage> = <length> | <percentage>

Example

HTML

<section>
<div class="shape"></div>
We are not quite sure of any one thing in biology; our knowledge of geology
is relatively very slight, and the economic laws of society are
uncertain to every one except some individual who attempts to set them
forth; but before the world was fashioned the square on the hypotenuse
was equal to the sum of the squares on the other two sides of a right
triangle, and it will be so after this world is dead; and the inhabitant
of Mars, if he exists, probably knows its truth as we know it.</section>

CSS

section {
  max-width: 400px;
}

.shape {
  float: left;
  width: 150px;
  height: 150px;
  background-color: maroon;
  clip-path: polygon(0 0, 150px 150px, 0 150px);
  shape-outside: polygon(0 0, 150px 150px, 0 150px);
  shape-margin: 20px;
}
