Answer 1

Bogdan Constantin You can use local storage. It will keep data in browser session until you didn't quit the browser but remember you need to destroy it after finishing your work so that you can check again for other questions.

Answer 2

in js way:-

Use document.onload event and in
add a fxn to add a class of active (define it in css) using btn1.classList.add("active");

So document.onload will add that class on btn as the document loaded / indirectly refresh as refresh will aslo load the document.
