Introduction: In this blog post, we’ll explore how to create a sleek and stylish calculator using HTML, CSS, and JavaScript. This calculator is not only functional but also aesthetically pleasing, with a dark mode option for added customization. We’ll break down the code and explain how it works step by step.

HTML Structure:

The HTML structure of the calculator is straightforward. It consists of:

  • A header with the title “Calculator” and a reference to an external CSS file.
  • A dark mode button to toggle the theme.
  • A <div> element with the class “calculator,” which contains the entire calculator UI.
  • Inside the calculator <div>, there’s a paragraph with the creator’s name and two main sections: the input display and the numeric keypad.
  
CSS Styling:
  
The CSS styling defines the visual appearance of the calculator. Here are some key styles applied:
  • The calculator is centered on the page with a light gray background and rounded edges for a modern look.
  • The input field is styled with a white background and gray text, giving it a clean and minimalistic appearance.
  • Buttons for numbers, operators, and other functionalities are styled differently, with clear color-coding to make them easily distinguishable.
  • The dark mode is implemented by toggling the “dark-mode” class, which changes the background and text colors to create a dark theme.
  
JavaScript Functionality:
  
  • The JavaScript code handles the dark mode toggle. It listens for a click event on the dark mode button and toggles the “dark-mode” class on the <body> element. This simple JavaScript function instantly transforms the calculator’s appearance between light and dark themes.
  
Conclusion:
  
Creating a stylish calculator like this one involves a combination of HTML for structuring the page, CSS for styling, and JavaScript for interactivity. The dark mode feature adds a layer of personalization to the calculator, making it visually appealing to a wider audience.
  
Feel free to use and modify this code as a starting point for your own web-based calculator projects. With some additional JavaScript, you can implement the calculator’s logic for performing calculations based on user input. This project is a great way to practice your front-end web development skills and create a useful tool in the process.

For more advanced features, you can extend the calculator to perform arithmetic operations or add memory functionality. The possibilities are endless, and this project serves as a fantastic foundation for further exploration in web development.
