I created a website using html and css about the impact of infrared.  Some parts still do not work but it looks nice.  It has been put online using bitballoon.

https://www.bitballoon.com

Here is sample of the code:  first the html part and then the css part of the code.

We have the resulting website I created accessible by anyone:

Please give it a try.
