The fork of Shapes and Colors demonstrates basic SVG shapes—circles and rectangles—arranged in two rows with default black fills, then explicit red and green fills, followed by a grouped set with a light blue fill and black stroke. A third group uses CSS classes to apply thick black strokes to lines and a polyline path, with rounded caps and joins, all scaled by a transform. SVG elements are hand-coded in HTML, with styling handled entirely through a linked stylesheet.
