  2. Create Input Fields: Inside the <body> section, add input fields for the two numbers between which you want to calculate the percentage. You can use the <input> element with the type attribute set to “number” to ensure that users can only enter numerical values.
  3. Add a Clickable Button: Insert a button using the <button> element, and set its onclick attribute to a JavaScript function that will perform the percentage calculation. Give meaningful IDs to the input fields so that you can easily reference them in your script.
