This tool uses a text editor on one side and an iframe (a sandboxed inline frame) on the other. As you type your HTML, CSS, and JavaScript code into the editor, it is instantly written into the iframe, causing it to render and display your code as a live webpage.
Yes. The preview pane is a sandboxed iframe. This is a security measure that isolates the previewed code from the main webpage, restricting its ability to perform potentially malicious actions. All processing is done in your browser, and no code is ever sent to our servers.
Absolutely. You can write CSS within `<style>` tags and JavaScript within `<script>` tags, just as you would in a regular HTML file. The live preview will render your styles and execute your scripts.
Simply use the "Clear" button next to the code editor. This will erase all the content in the editor and reset the live preview, allowing you to start fresh with a blank slate.
