Example Code

Steps to reproduce (docs website. no Python code involved):

1. Open https://fastapi.tiangolo.com/fastapi-cli/
2. Scroll to the first termynal/bash block showing `$ fastapi dev`
3. Click the copy button (top-right of the code block)
4. Paste into a text editor

Actual result:
<font color="#4E9A06">fastapi</font> dev

Expected result:
fastapi dev

Page that works correctly (for comparison):
https://fastapi.tiangolo.com/#run-it — copy gives plain `fastapi dev`

Source markdown (docs/en/docs/fastapi-cli.md):
$ <font color="#4E9A06">fastapi</font> dev

Description

Problem: On some docs pages, the copy button on termynal terminal blocks copies HTML tags into the clipboard instead of the plain shell command.

What I'm doing: Reading the FastAPI docs and using the copy button to copy fastapi dev.

Expected: Clipboard contains fastapi dev

Actual: Clipboard contains <font color="#4E9A06">fastapi</font> dev

Cause: The $ ... command line in markdown contains HTML (e.g. <font color="#4E9A06">fastapi</font>) intended for terminal styling. Termynal's typing animation uses textContent for input lines, so the HTML never renders visually on the command but it remains in the hidden <code> element that MkDocs Material's copy button reads.

Related prior work:

• Can't copy commands from termynal code blocks #14002 — copy button was broken entirely (fixed)
• 🐛 Fix copy button in custom.js #14722 — restored copy + extracts input lines only; doesn't strip HTML from those lines

Proposed fix: Remove dead HTML from $ ... command lines in English docs, matching the homepage style ($ fastapi dev instead of $ <font...>fastapi</font> dev). The HTML doesn't affect display on input lines anyway.

Affected English files:

• docs/en/docs/fastapi-cli.md
• docs/en/docs/tutorial/first-steps.md
• docs/en/docs/tutorial/index.md
• docs/en/docs/deployment/manually.md
• docs/en/docs/deployment/server-workers.md

Same issue exists in translated docs. Happy to leave those for translators.

Question: Would a PR with this English docs fix be welcome?

pasted text includes HTML tags like <font color="#4E9A06">fastapi</font> dev instead of plain fastapi dev.
