📄 Description
In this tutorial we’ll build a Captcha fill check feature using HTML, CSS, and JavaScript. You’ll learn how to create a simple CAPTCHA (text or math-based), validate user input in real time, show success/error feedback, and prevent simple automated submissions. This is ideal for signup forms, contact forms, or any UI that needs a lightweight bot check without external services.
*What you’ll learn:*
• Create a CAPTCHA UI (text or simple math) with HTML
• Style the CAPTCHA and feedback messages using CSS
• Generate random CAPTCHA values in JavaScript
• Validate the user input on submit and in real time
• Show success and error states with animations
• Add basic retry and refresh CAPTCHA functionality
• Handle edge cases and improve UX (case sensitivity, trimming)
