Definition and Usage

The addColorStop() method specifies the colors and position in a gradient object.

The addColorStop() method is used together with createLinearGradient() or createRadialGradient().

Note: You can call the addColorStop() method multiple times to change a gradient. If you omit this method for gradient objects, the gradient will not be visible. You need to create at least one color stop to have a visible gradient.

JavaScript syntax: gradient.addColorStop(stop, color);

Parameter Values

Parameter Description Play it
stop A value between 0.0 and 1.0 that represents the position between start and end in a gradient Play it »
color A CSS color value to display at the stop position Play it »
