Your file is ready! To embed it in your blog, you have two options: **Option 1 — iframe embed** (easiest, works on any platform): ```html ``` **Option 2 — Direct paste** — just copy the full HTML into your blog post editor (works on WordPress, Ghost, etc. with a custom HTML block). The file supports **light & dark mode** automatically, is **mobile-responsive**, and fetches live rates from a free API with a graceful offline fallback.
