SVG Gradients - Linear
SVG Gradients
A gradient is a smooth transition from one color to another. In addition, several color transitions can be applied to the same element.
There are two main types of gradients in SVG:
- Linear
- Radial
SVG Linear Gradient - <linearGradient>
The <linearGradient> element is used to define a linear gradient.
The <linearGradient> element must be nested within a <defs> tag. The <defs> tag is short for definitions and contains definition of special elements (such as gradients).
Linear gradients can be defined as horizontal, vertical or angular gradients:
- Horizontal gradients are created when y1 and y2 are equal and x1 and x2 differ
- Vertical gradients are created when x1 and x2 are equal and y1 and y2 differ
- Angular gradients are created when x1 and x2 differ and y1 and y2 differ
Example 1
Define an ellipse with a horizontal linear gradient from yellow to red:
Here is the SVG code:
Example
<svg height="150" width="400">
<defs>
<linearGradient id="grad1" x1="0%" y1="0%" x2="100%" y2="0%">
<stop offset="0%" style="stop-color:rgb(255,255,0);stop-opacity:1" />
<stop offset="100%" style="stop-color:rgb(255,0,0);stop-opacity:1" />
</linearGradient>
</defs>
<ellipse cx="200" cy="70" rx="85" ry="55"
fill="url(#grad1)" />
</svg>

Code explanation:
- The id attribute of the <linearGradient> tag defines a unique name for the gradient
- The x1, x2, y1,y2 attributes of the <linearGradient> tag define the start and end position of the gradient
- The color range for a gradient can be composed of two or more colors. Each color is specified with a <stop> tag. The offset attribute is used to define where the gradient color begin and end
- The fill attribute links the ellipse element to the gradient
Example 2
Define an ellipse with a vertical linear gradient from yellow to red:
Here is the SVG code:
Example
<svg height="150" width="400">
<defs>
<linearGradient id="grad2" x1="0%" y1="0%" x2="0%" y2="100%">
<stop offset="0%" style="stop-color:rgb(255,255,0);stop-opacity:1" />
<stop offset="100%" style="stop-color:rgb(255,0,0);stop-opacity:1" />
</linearGradient>
</defs>
<ellipse cx="200" cy="70" rx="85" ry="55" fill="url(#grad2)" />
</svg>

Example 3
Define an ellipse with a horizontal linear gradient from yellow to red, and add a text inside the ellipse:
Here is the SVG code:
Example
<svg height="150" width="400">
<defs>
<linearGradient id="grad3" x1="0%" y1="0%" x2="100%" y2="0%">
<stop offset="0%" style="stop-color:rgb(255,255,0);stop-opacity:1" />
<stop offset="100%" style="stop-color:rgb(255,0,0);stop-opacity:1" />
</linearGradient>
</defs>
<ellipse cx="200" cy="70" rx="85" ry="55"
fill="url(#grad3)" />
<text fill="#ffffff" font-size="45" font-family="Verdana" x="150" y="86">
SVG</text>
</svg>
