  • Basic Structure: 
    • <!DOCTYPE>

        • <optgroup>
        • <fieldset>
        • <label>
    • HTML attributes

URL Structure

What's URL and why they sometimes suck?

  • scheme://domain:port/path?query_string#fragment_id
  • The scheme we're using it HTTP (HyperText Transfer Protocol) or HTTPS (Secure HyperText Transfer Protocol)
  • A domain is something like "art.lehman.edu", the port is always 80, which the browsers assumes. This section could also be an IP address of the host machine.
  • Immediatly following the domain, after the  / is the filepath, similar to filepaths on any other device. This is what the server uses to find the document being referenced.
  • the ?query#fragment_id refers to any variables that are being passed in the URL and an anchor position in the target document
