Embed Coplain Calculators on Your Site

How to add a calculator to your page

1. Open the calculator’s full page from the list below, scroll past the FAQ and expand “Embed this calculator”.
2. Select “Copy embed code”, or select the code in the box and copy it.
3. Paste the code into an HTML or custom-code block on your page. Keep the credit paragraph under the iframe.
4. Optional: keep the script line so the frame grows and shrinks to fit the calculator. If your platform strips scripts, the iframe still works at the height in the code; change height="…" to suit.

Live preview: OEE Calculator

Everything inside the box is what readers see in the frame on your page; try it. The code below the box produces it.

Good to know

• The frame follows the reader’s light or dark system setting. Add ?theme=light or ?theme=dark to the iframe src to force one.
• The embed shows only the calculator and its credit line: no navigation, no cookie banner and no analytics scripts.
• Embed pages are marked noindex and point search engines at the full calculator page, so they will not compete with your own page in search.
