This is the Overview panel. It gives you a high-level summary of what this interface is about. Tabs are a common navigation pattern that lets users switch between related sections of content without leaving the page.
Each tab is a real <button> element with the correct
ARIA roles, states, and keyboard support so that screen-reader users and
keyboard-only users can navigate it just as comfortably as mouse users.
The Details panel contains more in-depth information. Here you might list features, technical specifications, or any other structured content relevant to the topic at hand.
Use the Contact panel to reach out. In a real application this might contain a form, an e-mail address, or a map. For demonstration purposes the content is kept simple.
Feel free to copy this self-contained file and adapt it to your own project. All styles and scripts are inlined so it works offline straight from the file system.
