I'm Low Nam Lee — a full-stack developer who enjoys working across the stack and exploring complex technical problems. I build, experiment, and share what I learn through my work and projects. Feel free to look around

This is a hands-on GitHub README compatibility lab. Each test explains what should happen on the rendered profile. Some tests are intentionally unsupported negative controls.

Change GitHub between light and dark themes and refresh this page. The banner should change color. The dot should move unless your system requests reduced motion, in which case a static yellow banner should appear.

• Hover over this tooltip link without clicking.
• Hover over the banner above to test its image tooltip.
• Click the badge below. It should behave like a button but navigate to the website rather than execute code inside the README.
• Click this anchor link to jump back to the beginning of the lab.

These disclosures share the same name. On a current browser, opening one should close the other.

Accordion panel A — click me

This panel starts open. It contains Markdown, an image, and a nested disclosure.

Nested disclosure test

If you can read this, nested <details> works too.

These look like controls, but checkboxes in a README should be disabled and should not save changes:

• Incomplete README task
• Completed README task

The first image is an externally generated animated SVG. The second is a dynamic badge whose value should change after new commits, although GitHub's image proxy may cache it.

The diagram should render. Try clicking the README node. GitHub may show link behavior, block a normal click, or only allow opening it in a new tab; this test documents the current behavior.

    click R "https://github.com/lownamlee/lownamlee" "Open the repository"

This should render as a GitHub-provided interactive map. Try panning, zooming, and selecting the Singapore and Kuala Lumpur points.

    }
  ]
}

This should render as a tetrahedron in GitHub's 3D viewer. Try dragging to rotate it and scrolling to zoom.

The link below is an intentional negative test. GitHub should remove its javascript: destination, so it should render as plain text or an inert link rather than execute:

Direct bookmarklet installation attempt

For a manual test, copy the following text into the URL field of a new browser bookmark, open any ordinary page, and click the bookmark:

javascript:(()=>{alert('README bookmarklet test: the manually installed bookmarklet works')})()

A real drag-to-install bookmarklet would need to live on the linked website or another normal HTTPS page, not inside this README.

Open this section to see what GitHub removes or converts to plain text. No control below is expected to execute inside the rendered README.

This sentence has a clickable footnote reference.¹
