Open up Google Chrome's Developer Tools and add some CSS and Javascript you learned in the previous video "HTML, CSS and Javascript" into Tim's website here: http://info.cern.ch/hypertext/WWW/TheProject.html
Remember:
Elements tab is for the HTML
Style tab is for the CSS
Console tab is to enter javascript.
If you get stuck, re-watch the previous video. Let's see what you can do. Good Luck!
