Jennifer Kyrnin’s Current Work

Work in Progress

Jennifer is working on two major projects right now. Watch this site for more information.

  • Teach Yourself Cool CSS
    I have been frustrated by the number of books out there that teach only the rudimentary basics of CSS, and don’t get into any of the really cool features and things that CSS can do. Don’t leave your sites boring and old with plain old backgrounds and colors, learn the really cool CSS that modern browsers are now capable of!
  • Front End Web Development course – Subject Matter Expert
    A video driven course that will teach you HTML, CSS, JavaScript, jQuery, and Git for web development. I am very excited about this course as it covers a lot of information about modern web development.
