HTML editor

You write HTML on the left and see the result on the right, live.

Fragment or whole page. If you write just a snippet (for example <h1>Hello</h1>), it is rendered on a page with the house style. If you start with <!doctype html> or <html>, your document is shown as is, with your own CSS and JavaScript. The Template button drops in a skeleton to start from.

Sandboxed and safe. The result runs in an isolated frame: your HTML and your JS work, but they can't touch this page or your data.

toolbarButtons that wrap the selection in a tag or insert a snippet (list, table, image…).
Ctrl/⌘ B<strong> around the selection.
Ctrl/⌘ I<em> around the selection.
severalYou can keep several documents, import and export them as .html. Everything is saved in this browser.
