You can do this. Either connect your laptop to your Ipad's hotspot or make sure laptop and ipad are connected to same network.

Run ifconfig in your terminal and look for en0, en1 or en (usually it will be en0). `en` are the ethernet interfaces which are WIFI interfaces in this case. Look for that IP.

Example (below the IP is 192.168.0.100)

Now spin up a small server which takes care of your html pages. This server should be served over the IP you just found.

This can be easily done with any. In php php -S IP_ADDRESS_HERE:PORT -t LOCATION_TO_BE_SERVED
Considering the above it it could be something like this. php -S 192.168.0.100:8085 -t LOCATION_TO_HTML_PAGES

Open a browser in your ipad and visit that IP with port.

There is an alternative way. You can use tunnels like Nrok, serveo.net or github.com/alexellis/inlets

Hope this helps.
