Create a Calculator Using HTML, CSS, and JavaScript

Do you want to Create a Calculator in HTML and CSS? To create a simple calculator using HTML and CSS you can use our code.

To create a simple calculator using HTML and CSS, you will need to use the following steps:

1. Create the HTML structure for the calculator. This will include the container element for the calculator, as well as the input elements for the numbers and the operator buttons.
2. Style the calculator using CSS. This will include setting the size and layout of the calculator, as well as styling the buttons and input elements to make them look attractive.
3. Add JavaScript code to handle the calculation logic. This will involve writing functions to handle the different operations (e.g. addition, subtraction, etc.), as well as attaching event handlers to the buttons to trigger the calculations when they are clicked.

Here is an example of a simple calculator using HTML, CSS, and JavaScript:

HTML Code–

<div id="calculator">
  <input type="text" id="display">
  <button class="operator" value="+">+</button>

  <button class="operator" value="/">/</button>
  <button class="number" value="7">7</button>
  <button class="number" value="8">8</button>
  <button class="number" value="9">9</button>
  <button class="number" value="4">4</button>
  <button class="number" value="5">5</button>
  <button class="number" value="6">6</button>
  <button class="number" value="1">1</button>
