Prompt given to the model

Build a "Featured offers" carousel in a single self-contained HTML file (inline CSS and JS, no build step, no external libraries). Show one promotional slide at a time from a set of three. Include a left-pointing arrow icon button to go to the previous slide, a right-pointing arrow icon button to go to the next slide, and a row of three small round icon buttons below the slide — one per slide — to jump directly to any of them. The first slide is shown when the page first loads. Use this exact content for the three slides, in this order: 1. Heading: "Summer sale". Body: "Save 20% on all outdoor furniture until the end of the month." Link: "Learn more" (href="#"). 2. Heading: "New arrivals". Body: "Browse this week's new homeware collection." Link: "Learn more" (href="#"). 3. Heading: "Free shipping". Body: "Free shipping on orders over $50, this week only." Link: "Learn more" (href="#"). Output the complete code in one HTML code block.

Notes on this run

Skill off

Generation 1 has role="region" and aria-roledescription applied to the <main> element. Those attributes shouldn't be applied to <main> because they override the main landmark role. The carousel include the pages h1 which belongs to the main page and not the carousel content.
