Website Construction Summary (Cont.)

  1. Creating Web Pages Using HTML
  2. HTML stands for Hyper Text Markup Language, which is a markup language for describing web pages. Create a new folder such as
       ~/public_html/demo/OracleJSON/
    on your account at the server undcemcs02.und.edu, where the tilde slash (~/) is the beginning of a path to a file or directory below the user’s home directory. In the OracleJSON/ folder, use Emacs (or any other text editor) to create the following three HTML files named:

    • index.html, the homepage,
    • Students.html, the data page, and
    • About.html, about the developer.
