This example displays a simple HTML page with a single paragraph element. The text reads “Je suis content!” and is preceded by a decorative ASCII-art cat rendered using a CSS `:before` pseudo-element. The cat’s shape is defined with a `white-space: pre` monospace string inside a `content` property, while a scoped `<style>` block confines the styling to that paragraph. No JavaScript or data-visualization libraries are used; the page relies solely on plain HTML and CSS to produce the visual output.
