Having trouble inputting an interactive resource

Please if anybody can help! I would like to input an item into my exhibit that is an interactive source. I have tried downloading the code and inputting it as a .exe file but have had a lot of trouble with that; the Omeka program says that I can extract the resource right from a website but I am not understanding how to do that. Every time I try saving the webpage I get an error message saying that .html is forbidden. How can I input my interactive resource?

For reference, it is the interactive periodic table from this site: http://www.rsc.org/periodic-table/alchemy

If you are able to figure this out with me I would really appreciate it!
