Application for android on html5, how to implement data loading?

Question

HTML

Hello, I have not previously encountered the development of applications for smartphones, I decided to study a little and came across the possibility of developing an application in html5.
Let's say I need a simple application in which there are 2 buttons \ tabs and they have some textual information that is always relevant. I think it's enough for me, for example, an html5 application with one page. How is this data loaded?
That is, you need a certain server from where the html page will simply be loaded? On this server there will be a database from which the data will be loaded? Or maybe it's something like a frame?
Explain please.
