use HTML and external CSS write code:

1)You should include an animation. This animation would be simply to change the background color from cyan to green and the color of the font should change from the black (default) to white. You can set up the time to be between 5 and 10 seconds and the animation should stop with the background color green and the font color white. Other than this animation, the rest of the page should be kept the same way as the original, including the background color, size, and color of the font, etc. (all, of course, being determined by CSS).

2) Extra credit (1 point) includes an animation that will act as a banner with a sentence to go from the left to the right side of the page without interruption should be a continuous and infinite movement. Can be a short sentence in the banner that you will create - you will not find the words/sentence in the homework file. The "banner" should be shown at the top part of the page but below the first heading (look at the file/short movie shown here below showing how the banner should be animated). Do not use obsolete HTML to create the banner and the banner should be seen all time
