How can i host Html5 game in website and use it on my app

Instead of searching iframe in source code and copying other game website can I make html5 games in my app by myself I just want to make some simple html5 games by myself or is it possible that i copy html from the website and paste it in kodular using the html component .
or make a free website host the game in that site and use it on my app.
What i just wanna do is just make an app which i own completely and can place ads on them.

Unfortunately, you cannot place ads next to the game unless the webviewer content is owned by you.
