Visual HTML Editor

For ninety percent of HTML work you don't need a full IDE. You need to paste a snippet, see how it renders, tweak a class or attribute, and copy the result somewhere else. Spinning up a Vite project, configuring a dev server and opening a browser tab for a five-line table is an absurd amount of ceremony. A split-view editor with instant preview compresses that loop to nothing — every keystroke becomes a feedback signal.

This is why developers, marketers and CMS editors keep a lightweight HTML sandbox open in a tab. Need to check how a Google Docs export will look once pasted into a blog template? Sandbox. Debugging a stubborn email layout that breaks in Outlook? Sandbox. Validating that a hand-written table renders with the right column widths? Sandbox. The tool below is designed for exactly those moments — fast, focused and disposable.

Reading raw HTML is not the same as seeing it rendered. Missing closing tags, unbalanced quotes, swapped class names and stray inline styles often look fine in source but render obviously wrong in a browser. A live preview surfaces those errors instantly — a row that should be 50% wide suddenly fills the container, a heading that should be h2 looks identical to body text because the class didn't apply, an image that should have a width turns out to be unconstrained.

Live preview is also the fastest way to test CMS theme behaviour. Paste your post HTML into the editor, then paste it into your CMS preview. If the rendering differs, you know the CMS is injecting styles or wrappers, and you can adjust your source accordingly without playing email-tennis with a designer.

Strip styles before pasting into a CMS. Word, Google Docs and Notion all emit verbose inline styles that fight your theme. Paste into the editor, remove the style attributes, then paste into the CMS.

Wrap reusable blocks in containers. A single root <div> with a clear class name makes the snippet portable across themes.

Use semantic tags, not styled divs. <article>, <section>, <nav> and <aside> render the same as div but help screen readers and search engines understand your structure.

Test at multiple widths. What looks perfect at desktop width often collapses on mobile. Resize the preview pane to spot responsive issues before publishing.

Keep a snippet library. The browser draft autosaves, so the editor doubles as a scratchpad for HTML blocks you reuse across projects.
