How can I make a simple app in solo learn

Question

I means how can I create different pages of app in one html file

Answer 1

You cant link multiply html files here in sololearn, but you can make single page applications, where you change content of page.

So when user click on link you change page content to be new content.
For this you would need to learn javascript (event listeners, DOM, changing style using js)

Answer 2

Here is example code, I had used switch to select what page to display:
