showHTML is a Firefox browser extension designed for developers and web enthusiasts to enhance their understanding of HTML structure. This tool provides a straightforward interface that displays a text stripe at the top or bottom of any webpage. As users hover over different elements, they receive real-time information about the HTML tags, IDs, and classes associated with those elements, making it easier to analyze and learn from existing web pages.

The extension is user-friendly, allowing users to move the text stripe to their preferred position within the browser window. By clicking on the stripe, users can toggle its location seamlessly, ensuring that it does not obstruct their view while browsing. showHTML is ideal for anyone looking to deepen their knowledge of web development or streamline their coding process.
