Python makes it easy to run a simple http server from any directory on your system. From command line execute the following command from the directory you would like the server to run from: $ python -m SimpleHTTPServer 8080
A simple http server will be running with the root being whatever directory you executed the above command from. The page will be accessible from the following URL:
http://localhost:8080
To access the site from another device, check your ip:
$ ifconfig en0
And replace it in the URL instead of localhost, in the above link.
Using another server? Or have a better way to run the above command, leave a comment below.
