+# <p align="center">Ugly Number Calculator</p>
+
+## Description :-
+
+This is a simple web application that allows users to check if a given number is a ugly number or not. 
+An ugly number is a positive integer whose prime factors are limited to 2, 3, and 5. 
+For example, 6 is a ugly number as it have only 2 and 3 as prime factor.
+
+## Tech Stacks :-
+
+- HTML
+- CSS
+- JavaScript
+
+## Features :-
+
+- Users can input a number.
+- Upon clicking the "Check for ugly" button, the application checks whether the entered number is a ugly number or not.
+- The result is displayed below the input field, indicating whether the number is ugly or not.
