Embedding Additional Files to make HTML Game

Hi all,

If this post should be somewhere else let me know. I am looking for a bit of support regarding an HTML Game I have made.

It consists of 3 files:
– HTML File
– CSS File
– JS File

I’m looking to have these embedded within a post on my website, however, I cannot find a way to do this. It may be simpler than I think but so far I have not been able to find a solution.

Any advice/guidance on this would be appreciated.

Paul
