A browser requests a URL, receives an HTTP response, and parses HTML into a document. A successful response does not guarantee that every image or stylesheet loaded.

Worked example

GET /courses HTTP/1.1
Host: academy.example

HTTP/1.1 200 OK

Put it into practice

Use browser developer tools to inspect one HTML request, its response status, and a missing image request.
