SVG Fun!
This example demonstrates a playful grid of twelve pink rectangles rendered as SVG elements. The visualization shows how CSS transitions and hover states can animate the shapes, changing their fill color and stroke width on mouse interaction. The code uses plain SVG and CSS, with rectangles defined in the HTML and styled via a `rect` selector. The transition property applies a 1000-millisecond easing effect, while the `:hover` pseudo-class modifies the visual style. The page is structured with a fixed 960x500 SVG viewport and a margin around the body.
