CSS 属性 shape-margin 用于设定由{{cssxref("shape-outside")}}创建的CSS形状的外边距。

{{EmbedInteractiveExample("pages/css/shape-margin.html")}}

这个外边距可以让你调整（浮动元素的）形状边缘与环绕内容之间的距离。

语法

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

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

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

值

<length-percentage>
使用{{cssxref("<length>")}}值，或者相对于元素容纳块的{{cssxref("<percentage>")}}值来设定形状的外边距。

范例

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;
}
