Using SVG Graphics in HTML for Scalable Vector Images
Learn how to integrate Scalable Vector Graphics (SVG) into your web pages for high-quality, resolution-independent images. This tutorial explains what SVG is, how to embed SVG code in HTML, and compares SVG to the Canvas element for different use cases. Includes code examples!
Using SVG Graphics in HTML
Scalable Vector Graphics (SVG) is a powerful way to incorporate vector-based graphics into your web pages. Unlike raster graphics (like JPEGs), SVG images don't lose quality when scaled.
What is SVG?
SVG (Scalable Vector Graphics) is a language for describing two-dimensional graphics in XML. SVG images are resolution-independent, meaning they remain sharp and clear at any size. Each element within an SVG image is accessible and can be individually manipulated with JavaScript or CSS.
Embedding SVG in HTML
You can embed SVG graphics within your HTML using the <svg> element. This element acts as a container for your SVG code.
(Simple SVG examples—circle, rectangle, rectangle with opacity and rounded corners, star, gradient ellipse and text—would be included here, each with its code, a description, and a "Try it Yourself" link. These are omitted for brevity but should follow a similar structure to the example below.)
Example: Simple SVG Circle
<svg width="100" height="100">
<circle cx="50" cy="50" r="40" stroke="green" stroke-width="4" fill="yellow" />
</svg>
(Output would show a yellow circle with a green border.)
SVG vs. Canvas
Both SVG and Canvas are used for graphics, but they differ significantly:
- SVG: XML-based; each shape is an object in the DOM, allowing for individual manipulation and event handling. Rendering can be slower with complex graphics.
- Canvas: Draws graphics pixel by pixel using JavaScript. Shapes are not individually addressable after rendering; changing a shape requires redrawing the entire scene. Excellent for game graphics.
SVG and Canvas Comparison
| Feature | SVG | Canvas |
|---|---|---|
| Resolution | Independent | Dependent |
| Event Handlers | Supported | Not Supported |
| Text Rendering | Good | Poor |
| Rendering Speed | Slower for complex graphics | Faster for complex graphics |
| Suitable for | Logos, illustrations, diagrams | Games, animations requiring high performance |
