Responsive Content Tester

A practical example: a project card

A short project name fits neatly in your design. Then someone adds a longer title, a detailed description and a button label with five words. Load your card HTML and try the Long translation preset, then compare Original and With tests at 375, 768 and 1,200 pixels. Small-screen stress combines long words, longer headings and larger text at 320 px; Missing assets hides image elements.

For Oxygen 6, use the results to inspect the relevant element and its parent Container in the builder. Review fixed widths, grid columns, flex wrapping, spacing and typography through the interface. The tool does not edit your Oxygen page or map findings to builder element IDs.

What the preview can show

Paste a component or a complete HTML document with inline CSS. You can also upload an .html file. Images embedded as raster data URLs are supported. Linked stylesheets, web fonts, remote images and JavaScript are blocked, so an exported website that depends on those files will not look exactly like the live page.

Use this first version for static layouts. It does not fetch arbitrary website URLs or simulate menus and other JavaScript interactions. A larger preview can scroll horizontally inside the workspace; that is separate from overflow detected within the page being tested.

Your HTML and results stay in this browser session. Compare common widths to inspect 375, 768 and 1200 px together, then download a combined report. Changing content or test settings clears the comparison so you can run it again. Export report and Copy readable report cover the single-width preview. Reset tests removes variations without changing your source. Review clipping, overlap and readability visually.
