Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.

CSS 属性 shape-margin 用于设定由shape-outside创建的 CSS 形状的外边距。

尝试一下

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

css
/* <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<length>值，或者相对于元素容纳块的<percentage>值来设定形状的外边距。

正式语法

shape-margin = 
  <length-percentage [0,∞]>  

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

范例

Adding a margin to a polygon

HTML

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 one exists, probably
  knows its truth as we know it.
</section>

CSS

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;
}
