{{CSSRef}}

The shape-outside CSS property defines a shape—which may be non-rectangular—around which adjacent inline content should wrap. By default, inline content wraps around its margin box; shape-outside provides a way to customize this wrapping, making it possible to wrap text around complex objects rather than simple boxes.

The shape-outside property is specified using the values from the list below, which define the float area for float elements. The float area determines the shape around which inline content (float elements) wrap.

Values

none
The float area is unaffected. Inline content wraps around the element's margin box, like usual.
<shape-box>
The float area is computed according to the shape of a float element's edges (as defined by the CSS box model). This can be margin-box, border-box, padding-box, or content-box. The shape includes any curvature created by the {{cssxref("border-radius")}} property (behavior which is similar to {{cssxref("background-clip")}}).
margin-box
Defines the shape enclosed by the outside margin edge. The corner radii of this shape are determined by the corresponding {{cssxref("border-radius")}} and {{cssxref("margin")}} values. If the border-radius / margin ratio is 1 or more, then the margin box corner radius is border-radius + margin. If the ratio is less than 1, then the margin box corner radius is border-radius + (margin * (1 + (ratio-1)^3)).
border-box

Defines the shape enclosed by the outside border edge. The shape follows the normal border radius shaping rules for the outside of the border.

padding-box

Defines the shape enclosed by the outside padding edge. The shape follows the normal border radius shaping rules for the inside of the border.

content-box

Defines the shape enclosed by the outside content edge. Each corner radius of this box is the larger of 0 or border-radius - border-width - padding.

{{cssxref("<basic-shape>")}}
The float area is computed based on the shape created by of one of inset(), circle(), ellipse(),  polygon(), or as added in the level 2 specification path(). If a <shape-box> is also supplied, it defines the reference box for the <basic-shape> function. Otherwise, the reference box defaults to margin-box.
{{cssxref("<image>")}}
The float area is extracted and computed based on the alpha channel of the specified {{cssxref("<image>")}} as defined by {{cssxref("shape-image-threshold")}}.
Note: {{glossary("User agent", "User agents")}} must use the potentially CORS-enabled fetch method defined by the HTML5 specification for all URLs in a shape-outside value. When fetching, user agents must use "Anonymous" mode, set the referrer source to the stylesheet's URL, and set the origin to the URL of the containing document. If this results in network errors such that there is no valid fallback image, the effect is as if the value none had been specified.

Interpolation

When animating between one <basic-shape> and a second, the rules below are applied. The values in the shape functions interpolate as a simple list. The list values interpolate as {{cssxref("<length>")}}, {{cssxref("<percentage>")}}, or {{cssxref("calc")}} where possible. If list values are not one of those types but are identical (such as finding nonzero in the same list position in both lists), those values do interpolate.

Examples

Funneling text

HTML

<div class="main">
  <div class="left"></div>
  <div class="right"></div>
  <p>
    Sometimes a web page's text content appears to be
    funneling your attention towards a spot on the page
    to drive you to follow a particular link. Sometimes
    you don't notice.
  </p>
</div>

CSS

.main {
  width: 530px;
}

.left,
.right {
  width: 40%;
  height: 12ex;
  background-color: lightgray;
}

.left {
  -webkit-shape-outside: polygon(0 0, 100% 100%, 0 100%);
  shape-outside: polygon(0 0, 100% 100%, 0 100%);
  float: left;
  -webkit-clip-path: polygon(0 0, 100% 100%, 0 100%);
  clip-path: polygon(0 0, 100% 100%, 0 100%);
}

.right {
  -webkit-shape-outside: polygon(100% 0, 100% 100%, 0 100%);
  shape-outside: polygon(100% 0, 100% 100%, 0 100%);
  float: right;
  -webkit-clip-path: polygon(100% 0, 100% 100%, 0 100%);
  clip-path: polygon(100% 0, 100% 100%, 0 100%);
}

p {
  text-align: center;
}
