How to create a Calculator in TailwindCSS with Tailwind CSS?

Now that we have a basic understanding of Tailwind CSS and why it is useful for creating a calculator, let's dive into the steps to create a calculator in Tailwind CSS.

Step 1: Set up the HTML structure

The first step is to set up the HTML structure for our calculator. We will use a simple HTML structure that consists of a display screen, numeric buttons, and function buttons. Here is the HTML code for our calculator:

<div class="calculator">
  <div class="display"></div>
  <div class="buttons">
    <button class="number">1</button>
    <button class="number">2</button>
    <button class="number">3</button>
    <button class="function">+</button>
    <button class="number">4</button>
    <button class="number">5</button>
    <button class="number">6</button>
    <button class="function">-</button>
    <button class="number">7</button>
    <button class="number">8</button>
    <button class="number">9</button>
    <button class="function">*</button>
    <button class="number">0</button>
    <button class="function">C</button>
    <button class="function">/</button>
    <button class="function">=</button>
  </div>
</div>

Step 2: Style the calculator using Tailwind CSS

The next step is to style our calculator using Tailwind CSS classes. We will use a combination of background colors, border colors, font sizes, and padding to style our calculator. Here is the Tailwind CSS code for our calculator:

.calculator {
  background-color: #f5f5f5;
  border: 1px solid #ccc;
  border-radius: 5px;
  padding: 10px;
  width: 300px;
}

.display {
  background-color: #fff;
  border: 1px solid #ccc;
  border-radius: 5px;
  font-size: 24px;
  height: 50px;
  margin-bottom: 10px;
  padding: 10px;
  text-align: right;
}

.buttons {
  display: grid;
  grid-template-columns: repeat(4, 1fr);
  grid-gap: 10px;
}

.number {
  background-color: #fff;
  border: 1px solid #ccc;
  border-radius: 5px;
  font-size: 24px;
  height: 50px;
  padding: 10px;
  text-align: center;
}

.function {
  background-color: #ccc;
  border: 1px solid #ccc;
  border-radius: 5px;
  color: #fff;
  font-size: 24px;
  height: 50px;
  padding: 10px;
  text-align: center;
}

Step 3: Add functionality to the calculator

The final step is to add functionality to our calculator. We will use JavaScript to handle button clicks and perform mathematical calculations. Here is the JavaScript code for our calculator:

const display = document.querySelector('.display');
const buttons = document.querySelectorAll('.number, .function');
let currentNumber = '';
let previousNumber = '';
let operation = null;

buttons.forEach(button => {
  button.addEventListener('click', () => {
    if (button.classList.contains('number')) {
      currentNumber += button.textContent;
      display.textContent = currentNumber;
    }

    if (button.classList.contains('function')) {
      if (button.textContent === 'C') {
        currentNumber = '';
        previousNumber = '';
        operation = null;
        display.textContent = '';
      }

      if (button.textContent === '=') {
        if (operation === '+') {
          display.textContent = parseInt(previousNumber) + parseInt(currentNumber);
        }

        if (operation === '-') {
          display.textContent = parseInt(previousNumber) - parseInt(currentNumber);
        }

        if (operation === '*') {
          display.textContent = parseInt(previousNumber) * parseInt(currentNumber);
        }

        if (operation === '/') {
          display.textContent = parseInt(previousNumber) / parseInt(currentNumber);
        }

        currentNumber = '';
        previousNumber = '';
        operation = null;
      }

      if (button.textContent !== 'C' && button.textContent !== '=') {
        previousNumber = currentNumber;
        currentNumber = '';
        operation = button.textContent;
      }
    }
  });
});
