|
||
| The **`stop-color`** [CSS](/en-US/docs/Web/CSS) property defines the color to use for an SVG {{SVGElement("stop")}} element within a gradient. If present, it overrides the element's {{SVGAttr("stop-color")}} attribute. | ||
|
|
||
| > [!NOTE] | ||
| > The `stop-color` property only applies to {{SVGElement('stop')}} elements nested in an {{SVGElement("svg")}}. It doesn't apply to other SVG, HTML, or pseudo-elements. | ||
|
|
||
| ## Syntax | ||
|
|
||
| ```css | ||
| /* <color> values */ | ||
| stop-color: red; | ||
| stop-color: hsl(120deg 75% 25% / 60%); | ||
| stop-color: currentcolor; | ||
|
|
||
| /* Global values */ | ||
| stop-color: inherit; | ||
| stop-color: initial; | ||
| stop-color: revert; | ||
| stop-color: revert-layer; | ||
| stop-color: unset; | ||
| ``` | ||
|
|
||
| ### Values | ||
|
|
||
| - {{cssxref("color_value", "<color>")}} | ||
|
|
||
| - : The color of the fill. This can be any valid CSS {{cssxref("color_value", "<color>")}} value. | ||

||
| ### Defining the color stops of SVG gradients | ||
|
|
||
| This example demonstrates the basic use case of `stop-color`, and how the CSS `stop-color` property takes precedence over the `stop-color` attribute. | ||
|
|
||
| #### HTML | ||
|
|
||
| We have an SVG with three {{SVGElement("rect")}} squares and three {{SVGElement("linearGradient")}} elements. Each gradient has four {{SVGElement("stop")}} elements creating gradients that go from black to white and then white to grey; the only difference between them is the `id` value. | ||
|
|
||
| ```html | ||
| <svg viewBox="0 0 264 100" xmlns="http://www.w3.org/2000/svg"> | ||
| <defs> | ||
| <linearGradient id="myGradient1"> | ||
| <stop offset="25%" stop-color="#000" /> | ||
| <stop offset="40%" stop-color="#fff" /> | ||
| <stop offset="60%" stop-color="#fff" /> | ||
| <stop offset="75%" stop-color="#333" /> | ||
| </linearGradient> | ||
| <linearGradient id="myGradient2"> | ||
| <stop offset="25%" stop-color="#000" /> | ||
| <stop offset="40%" stop-color="#fff" /> | ||
| <stop offset="60%" stop-color="#fff" /> | ||
| <stop offset="75%" stop-color="#333" /> | ||
| </linearGradient> | ||
| <linearGradient id="myGradient3"> | ||
| <stop offset="25%" stop-color="#000" /> | ||
| <stop offset="40%" stop-color="#fff" /> | ||
| <stop offset="60%" stop-color="#fff" /> | ||
| <stop offset="75%" stop-color="#333" /> | ||
| </linearGradient> | ||
| </defs> | ||
| <rect x="2" y="10" width="80" height="80" fill="url('#myGradient1')" /> | ||
| <rect x="92" y="10" width="80" height="80" fill="url('#myGradient2')" /> | ||
| <rect x="182" y="10" width="80" height="80" fill="url('#myGradient3')" /> | ||
| </svg> | ||
| ``` | ||
|
|
||
| #### CSS | ||
|
|
||
| We include a {{cssxref("stroke")}} and {{cssxref("stroke-width")}} outlining the rectangle. We define the colors of the first and last stops in each gradient, overriding their `stop-color` attribute values, using the `stop-color` property. Various CSS {{cssxref("color_value", "<color>")}} syntaxes are shown. | ||
|
|
||
| ```css hidden | ||
| svg { | ||
| border: 1px solid; | ||
| height: calc(100vh - 20px); | ||
| margin-bottom: 10px; | ||
| } | ||
| ``` | ||
|
|
||
| ```css | ||
| rect { | ||
| stroke: #333; | ||
| stroke-width: 1px; | ||
| } | ||
|
|
||
| #myGradient1 { | ||
| stop:first-of-type { | ||
| stop-color: #66ccff; | ||
| } | ||
| stop:last-of-type { | ||
| stop-color: #f4aab9; | ||
| } | ||
| } | ||
| #myGradient2 { | ||
| stop:first-of-type { | ||
| stop-color: yellow; | ||
| } | ||
| stop:last-of-type { | ||
| stop-color: purple; | ||
| } | ||
| } | ||
| #myGradient3 { | ||
| stop:first-of-type { | ||
| stop-color: hsl(0deg 100% 50%); | ||
| } | ||
| stop:last-of-type { | ||
| stop-color: hsl(20deg 100% 50%); | ||
| } | ||
| } | ||

| title: stop-opacity | ||

| page-type: css-property | ||
| browser-compat: css.properties.stop-opacity | ||
| --- | ||
|
|
||
| {{CSSRef}} | ||
|
|
||
| The **`stop-opacity`** [CSS](/en-US/docs/Web/CSS) property defines the opacity of a given color gradient stop in the SVG {{SVGElement("stop")}} element within an SVG gradient. If present, it overrides the element's {{SVGAttr("stop-opacity")}} attribute. | ||
|
|
||
| The property value impacts the {{cssxref("stop-color")}}'s alpha channel; it can increase the transparency of a `<stop>`'s color but can not make the color defined by the `stop-color` property more opaque. | ||
|
|
||
| > [!NOTE] | ||
| > The `stop-opacity` property only applies to {{SVGElement('stop')}} elements nested in an {{SVGElement("svg")}}. It doesn't apply to other SVG, HTML, or pseudo-elements. | ||
|
|
||
| ## Syntax | ||
|
|
||
| ```css | ||
| /* numeric and percentage values */ | ||
| stop-opacity: 0.2; | ||
| stop-opacity: 20%; | ||
|
|
||
| /* Global values */ | ||
| stop-opacity: inherit; | ||
| stop-opacity: initial; | ||
| stop-opacity: revert; | ||
| stop-opacity: revert-layer; | ||
| stop-opacity: unset; | ||
| ``` | ||
|
|
||
| ### Values | ||
|
|
||
| The `<opacity-value>` is a {{cssxref("number")}} or {{cssxref("percentage")}} denoting the opacity of the SVG gradient `<stop>` element. | ||
|
|
||
| - {{cssxref("number")}} | ||
|
|
||
| - : A numeric value between `0` and `1`, inclusive. | ||
|
|
||
| - {{cssxref("percentage")}} | ||
|
|
||
| - : A percentage value between `0%` and `100%`, inclusive. | ||
|
|
||
| With `0` or `0%` set, the stop is fully transparent. With `1` or `100%` set, the element is the full opacity of the `stop-color` value, which may or may not be partially opaque. | ||

| ### Defining the opacity of a SVG gradient color stop | ||
|
|
||
| This example demonstrates the basic use case of `stop-opacity`, and how the CSS `stop-opacity` property takes precedence over the `stop-opacity` attribute. | ||
|
|
||
| #### HTML | ||
|
|
||
| We have an SVG with a few {{SVGElement("polygon")}} stars and three {{SVGElement("linearGradient")}} elements: each has three {{SVGElement("stop")}} elements defining three color-stops that create a gradient going from blue to white to pink; the only difference between them is the `id` value. | ||
|
|
||
| ```html | ||
| <svg viewBox="0 0 250 120" xmlns="http://www.w3.org/2000/svg"> | ||
| <defs> | ||
| <linearGradient id="myGradient1"> | ||
| <stop offset="5%" stop-color="#66ccff" stop-opacity="1" /> | ||
| <stop offset="50%" stop-color="#fefefe" stop-opacity="1" /> | ||
| <stop offset="95%" stop-color="#f4aab9" stop-opacity="1" /> | ||
| </linearGradient> | ||
| <linearGradient id="myGradient2"> | ||
| <stop offset="5%" stop-color="#66ccff" stop-opacity="1" /> | ||
| <stop offset="50%" stop-color="#fefefe" stop-opacity="1" /> | ||
| <stop offset="95%" stop-color="#f4aab9" stop-opacity="1" /> | ||
| </linearGradient> | ||
| <linearGradient id="myGradient3"> | ||
| <stop offset="5%" stop-color="#66ccff" stop-opacity="1" /> | ||
| <stop offset="50%" stop-color="#fefefe" stop-opacity="1" /> | ||
| <stop offset="95%" stop-color="#f4aab9" stop-opacity="1" /> | ||
| </linearGradient> | ||
| </defs> | ||
| <polygon points="40,10 10,100 80,40 0,40 70,100" /> | ||
| <polygon points="125,10 95,100 165,40 85,40 155,100" /> | ||
| <polygon points="210,10 180,100 250,40 170,40 240,100" /> | ||
| </svg> | ||
| ``` | ||
|
|
||
| #### CSS | ||
|
|
||
| We include a {{cssxref("stroke")}} and {{cssxref("stroke-width")}} making the polygon path line visible. | ||
|
|
||
| Each `polygon` has a gradient background set using the {{cssxref("fill")}} property; the gradient's `id` is the `url()` parameter. We set `magenta` as the fallback color. | ||
|
|
||
| We define the opacity of the stops of each gradient using the `stop-opacity` property. | ||
|
|
||
| The SVG has a striped background to make the transparency settings more apparent. | ||
|
|
||
| ```css hidden | ||
| svg { | ||
| border: 1px solid; | ||
| height: calc(100vh - 20px); | ||
| margin-bottom: 10px; | ||
| background: repeating-linear-gradient( | ||
| to top left, | ||
| white 0 9px, | ||
| black 9px 10px | ||
| ); | ||
| } | ||
| ``` | ||
|
|
||
| ```css | ||
| polygon { | ||
| stroke: #333; | ||
| stroke-width: 1px; | ||
| } | ||
| polygon:nth-of-type(1) { | ||
| fill: url("#myGradient1") magenta; | ||
| } | ||
| polygon:nth-of-type(2) { | ||
| fill: url("#myGradient2") magenta; | ||
| } | ||
| polygon:nth-of-type(3) { | ||
| fill: url("#myGradient3") magenta; | ||
| } | ||
|
|
||
| #myGradient1 stop { | ||
| stop-opacity: 1; | ||
| } | ||
| #myGradient2 stop { | ||
| stop-opacity: 0.8; | ||
| } | ||
| #myGradient3 stop { | ||
| stop-opacity: 25%; | ||
| } | ||
| ``` | ||
|
|
||
| #### Results | ||
|
|
||
| {{EmbedLiveSample("Defining the opacity of a SVG gradient color stop", "300", "200")}} | ||
|
|
||
| The first star is fully opaque. The fill of the second star is 80% opaque because the color stops are slightly translucent; the `stop-opacity: 0.8;` overrode the `stop-opacity="1"` element attribute value. The fill of the last star is barely noticeable with color stops that are 25% opaque. Note the stroke is the same opaque dark grey in all cases. | ||
|
|
||
| > [!NOTE] | ||
| > Because we used the same `stop-opacity` value for all the sibling `<stop>` elements in the linear gradient, we could have instead used a single `<linearGradient>` with fully opaque stops, and set a value for each `<polygon>`s {{cssxref("fill-opacity")}} property instead. | ||
