SVG gradients and patterns can significantly enhance visual graphics. Gradients, linear or radial, add depth to shapes by transitioning between two or more colors. To create a gradient, define it within the defs element, then reference it using fill:url(#gradient-id). You can control direction in linear gradients with x1, y1, x2, y2 attributes; for radial gradients cx, cy, r dictate the focal point and radius.
Patterns are used to fill graphics with repeating images. Define them in defs, referencing via fill:url(#pattern-id). Attributes like width, height set pattern size while patternUnits=”userSpaceOnUse” allows pixel-based sizing. PatternContentUnits attribute controls child elements’ coordinate system.
For complex visuals, combine gradients and patterns. For instance, use a gradient as a pattern’s background color.
