HTML code to link

Full documents and snippets both work

A full document starts with <!DOCTYPE html> and has <head> and <body>. A snippet is just a piece — say a <table> or a styled <div>. Both convert. Browsers are forgiving: missing <html> or <body> tags are filled in automatically when the page loads.

One thing worth adding to a snippet is <meta name="viewport" content="width=device-width, initial-scale=1">. Without it, phones render the page zoomed out as if it were a desktop site.

Preview before you convert

Press Preview under the code box to render your HTML in a sandboxed frame right here. It is the same engine your visitors will use, so what you see is what they get — minus anything that needs other files you have not included.

Keep everything inline

Pasted code is a single file, so put CSS in a <style> tag and JavaScript in a <script> tag rather than linking to local files. Images can be hosted elsewhere and referenced by full https:// URL, or embedded as data URIs. If your project already has separate files, use ZIP to link instead.
