About HTML Live Preview
HTML Live Preview renders your HTML in a sandboxed frame as you type, giving you instant visual feedback without needing a browser tab, a local server, or any setup. It is great for quickly prototyping a snippet, testing a CSS style, or showing someone what a piece of markup looks like. The preview is isolated from the host page, so your scripts and styles do not interfere with the tool.
