Border is a HTML/CSS/JS web browser for Windows 96 made by Kelbaz. It uses HTML iframes to browse internet content. It is open-sourced on Github, and you can visit the repository here. The website is also available here.
Border aims at being a sophisticated, modern browser capable of doing many things traditional browsers do, such as theming and plugins (called 'Blugins'). It also has an API.
