HTML Editor Previewer

Frontend scratchpad workflow

A fast HTML, CSS, and JavaScript scratchpad for small interface experiments.

The HTML Editor Previewer is for trying a small idea without spinning up a full project. It is useful for testing markup structure, CSS behavior, a small interactive snippet, or a layout question before that idea graduates into a real app or component library.

I like this kind of scratchpad for focused experiments: one control, one responsive layout, one CSS state, or one bit of DOM behavior. Keeping the scope small makes the result easier to understand and easier to throw away if the idea does not work.

This tool is not a sandbox for untrusted code. JavaScript entered into the preview runs in your browser context, so treat pasted scripts with the same caution you would use anywhere else. For production work, move the proven idea into source control, tests, and the project build pipeline.
