Internet Explorer 9, Firefox, Opera, Chrome, and Safari support the createLinearGradient() method.
Note: Internet Explorer 8 and earlier versions, do not support the <canvas> element.
The createLinearGradient() method creates a linear gradient object.
The gradient can be used to fill rectangles, circles, lines, text, etc.
Tip: Use this object as the value to the strokeStyle or fillStyle properties.
Tip: Use the addColorStop() method to specify different colors, and where to position the colors in the gradient object.
JavaScript syntax: | context.createLinearGradient(x0,y0,x1,y1); |
