Scalable Vector Graphics

What is an SVG file?

An SVG (Scalable Vector Graphics) file is a vector image format that uses XML markup to define two-dimensional graphics. Unlike raster images (like JPEG or PNG), SVG images are composed of mathematical descriptions of shapes, paths, and colors, making them infinitely scalable without loss of quality. SVG files can include interactive elements and animations.

More Information

SVG was developed by the World Wide Web Consortium (W3C) and became a W3C Recommendation in 2001. The format was created to provide a vector graphics format for the web that could scale to any size while maintaining crisp, sharp edges. SVG has become increasingly popular with the rise of responsive web design and high-resolution displays.

SVG images are perfect for logos, icons, simple illustrations, and graphics that need to look sharp at any size. They can be styled with CSS, manipulated with JavaScript, and animated using various techniques. Modern web browsers have excellent SVG support, making it a reliable choice for web graphics.

SVG Format

SVG is based on XML and uses a hierarchical structure to define vector graphics:

Basic Elements

• <svg> - Root container element
• <rect> - Rectangles and squares
• <circle> - Circles
• <ellipse> - Elliptical shapes
• <line> - Straight lines
• <path> - Complex shapes using path data
• <polygon> - Multi-sided shapes
• <text> - Text elements

Advanced Features

• Gradients - Linear and radial color gradients
• Patterns - Repeating patterns for fills
• Filters - Visual effects like blur, shadows, lighting
• Clipping paths - Mask portions of elements
• Groups - Organize and transform multiple elements
• Definitions - Reusable elements and styles

Styling Options

• Inline styles - Style attributes on elements
• CSS styling - External or embedded stylesheets
• Presentation attributes - SVG-specific styling attributes
• CSS animations - Animate properties using CSS
• SMIL animations - SVG's built-in animation system
