Shapes and Colors with SVG and CSS
This example demonstrates fundamental SVG shapes and CSS styling within a static web page. It shows circles and rectangles with explicit fills, a group inheriting fill and stroke attributes, and a separate group of lines and paths. The rendering uses inline SVG elements with a scale transform, while CSS classes like `.lines` control stroke color, width, and line joins. No external libraries are used; the implementation relies purely on native SVG markup and a linked stylesheet.
