How to create a Pin Code Field with Tailwind CSS?

To create a Pin Code Field UI component with Tailwind CSS, follow these steps:

Step 1: Create the HTML markup

The first step is to create the HTML markup for the Pin Code Field component. We will create a set of input fields wrapped in a div element. Each input field will have a unique ID and a maxlength attribute set to 1, limiting the input to a single digit.

<div class="pin-code-field">
  <input type="text" id="digit-1" maxlength="1" />
  <input type="text" id="digit-2" maxlength="1" />
  <input type="text" id="digit-3" maxlength="1" />
  <input type="text" id="digit-4" maxlength="1" />
  <input type="text" id="digit-5" maxlength="1" />
  <input type="text" id="digit-6" maxlength="1" />
</div>

Step 2: Style the Pin Code Field component

Next, we will use Tailwind CSS classes to style the Pin Code Field component. We will use the grid system to layout the input fields in a 3x3 grid. We will also use border and padding classes to style the input fields.

<div class="pin-code-field grid grid-cols-3 gap-4">
  <input type="text" id="digit-1" maxlength="1" class="border border-gray-400 rounded-md p-2 text-center text-xl font-bold" />
  <input type="text" id="digit-2" maxlength="1" class="border border-gray-400 rounded-md p-2 text-center text-xl font-bold" />
  <input type="text" id="digit-3" maxlength="1" class="border border-gray-400 rounded-md p-2 text-center text-xl font-bold" />
  <input type="text" id="digit-4" maxlength="1" class="border border-gray-400 rounded-md p-2 text-center text-xl font-bold" />
  <input type="text" id="digit-5" maxlength="1" class="border border-gray-400 rounded-md p-2 text-center text-xl font-bold" />
  <input type="text" id="digit-6" maxlength="1" class="border border-gray-400 rounded-md p-2 text-center text-xl font-bold" />
</div>

Step 3: Add interactivity to the Pin Code Field component

Finally, we can add interactivity to the Pin Code Field component using JavaScript. We can listen for the input event on each input field and move the focus to the next input field when the user enters a digit.

const inputs = document.querySelectorAll('.pin-code-field input');

inputs.forEach((input, index) => {
  input.addEventListener('input', (event) => {
    const { value } = event.target;

    if (value.length === 1) {
      if (index < inputs.length - 1) {
        inputs[index + 1].focus();
      } else {
        inputs[index].blur();
      }
    } else if (value.length === 0) {
      if (index > 0) {
        inputs[index - 1].focus();
      }
    }
  });
});
