About the HTML Preview
This HTML preview renders your markup and CSS live as you type, with the code on one side and the result on the other. No file to save, no build step and nothing uploaded.
A live HTML preview is the fastest way to try something small. Checking how a flexbox rule behaves, testing a snippet from documentation, or confirming an email template renders — none of which justify creating a file and setting up a server.
Editing with the output visible changes how you work. Rather than saving and reloading, you adjust a value and watch the layout respond, which makes it far quicker to understand an unfamiliar CSS property.
Useful for teaching and for sharing a reproduction too. Everything runs in your browser, so a snippet containing internal markup or unreleased design work is not uploaded anywhere.
How to use the HTML Preview
- Write your HTML. Enter markup in the editor pane, with CSS in a style block.
- Watch it render. The preview updates as you type.
- Adjust and observe. Change a property and see the effect immediately.
- Copy the code. Take the working snippet into your project.

Frequently asked questions
Can I include CSS?
Yes. Put it in a style block in your markup and it applies to the preview immediately.
Does JavaScript run in the preview?
The preview renders your markup and styles. Keep snippets to HTML and CSS for predictable results.
Do I need to save a file?
No. There is no file, server or build step — you type and it renders.
Is my code uploaded?
No. Everything renders in your browser, so internal markup stays local.
Can I preview an email template?
Yes, though email clients vary considerably. Use it for a first look, then test in a real client.
