Detailed Overview
The Live HTML Viewer is a real-time split-screen editor for HTML, CSS and JavaScript, with an interactive live browser preview, an HTML tag tree inspector and a DOM structure analyser. It lets you experiment with web code and see the result instantly, without setting up files or a local server, which makes it ideal for learning, prototyping and debugging small pieces of a page.
To use it, write or paste your HTML, CSS and JavaScript and watch the preview update as you type. Use the tag tree inspector to check the structure of your document, especially when a layout behaves unexpectedly, since a misplaced or unclosed tag often explains the problem. Test responsive behaviour by resizing the preview, and iterate quickly: change, observe, and change again.
Treat the preview as a sandbox, not a final test. External resources, fonts and scripts may behave differently here than on a real site, and features that depend on a server, such as form submissions or authentication, will not work the same way. When a prototype is ready, move it into a real project and test it in actual browsers and on real devices.
One honest limitation: the preview environment is not a full browser testing setup. It cannot replace testing in different browsers, on different devices, or with assistive technologies, and you should not paste sensitive code or credentials into any online editor, including this one.
