Active Button or Disabled Buttons:
In Bootstrap 4, buttons can be displayed in an active (appears pressed) or disabled (appears unclickable) state.
  • To make a button appear pressed, the .active class is used.
  • To make a button unclickable, the disabled attribute is applied.
  • For <a> elements, since they don't support the disabled attribute, the .disabled class is used to visually disable them.

<!DOCTYPE html>  
<html lang="en">  
<head>  
  <title>Bootstrap Example</title>  
  <meta charset="utf-8">  
  <meta name="viewport" content="width=device-width, initial-scale=1">
