tagLiner is a free Chrome extension designed to assist web developers by visually highlighting heading elements on a webpage. By clicking the extension's button, users can frame all heading tags (h1 to h6) with a red border, making them easily identifiable. Additionally, a badge displaying the corresponding heading text appears at the bottom right corner of each framed heading, providing quick reference.

The extension also features a convenient list of all header elements displayed in a box at the top left corner of the page. This functionality allows developers to efficiently review and manage heading tags in published and active web pages, enhancing their workflow and ensuring proper heading structure for better SEO and accessibility.
