Educational use
The library provides educational explanations, sample code and browser-side practice. Examples use fictional data unless explicitly stated. Adapt and test code for your own requirements before production use.
Limits of examples
Examples and diagnostics do not replace a security review, server-side validation, legal advice or a complete accessibility assessment. Quizzes and completion indicators are informal learning aids, not a qualification or certification.
Responsible practice
Use your own test data. Do not enter passwords, payment information, private customer records or other sensitive information in examples. Do not use the service to harm systems or interfere with other users.
Software and content
The distributed theme and plugin include their software license notices. Third-party standards and linked documentation retain their own terms. Contact hello@htmlcoderunner.com for questions about reproducing teaching material or reporting a rights concern.
Other services
External resources and the separate main runner may have their own terms. Browser and standards changes can affect examples; report a reproducible problem through Contact.
