This example demonstrates how SVG shapes and colors can be styled using Cascading Style Sheets (CSS). It shows circles and rectangles with varying fill properties, some defined directly as attributes and others through CSS classes, alongside lines and paths with stroke settings. The Scalable Vector Graphics (SVG) markup uses grouping and transform elements to organize and position the shapes. The accompanying CSS stylesheet applies stroke width, colors, and line join and cap styles to the line elements and path.
