What I can do to show some text after clicking onto a button?

Answer 1

You need JavaScript to handle click event in Html. The easiest option is writing a JavaScript function and call the function on the onclick attribute of the html.

You will need some dom manipulation.

document.getElementbyId which will be stored in a variable.

or this

<button onclick="this.innerHTML=Date()">The time is?</button>

or any other element you want to use.
