The <radialGradient> HTML5 tag is used to draw SVG Gradients. Yes, modern browsers support it.
The following is the HTML5 version of an SVG example that would draw an ellipse using the <ellipse> tag and would use the <radialGradient> tag to define an SVG radial gradient. Similar way you can use the <linearGradient> tag to create SVG linear gradient.
