How to create a Form Login with Tailwind CSS?

Now that you understand what Tailwind CSS is and why it is a good choice for building a Form Login UI component, let's dive into how to create one.

Step 1: Set up the HTML structure

The first step is to set up the HTML structure for the Form Login UI component. Here is an example:

<div class="flex justify-center items-center h-screen">
  <form class="bg-white p-6 rounded shadow-md">
    <h2 class="text-2xl font-bold mb-6">Login</h2>
    <div class="mb-4">
      <label class="block text-gray-700 font-bold mb-2" for="username">
        Username
      </label>
      <input
        class="appearance-none border rounded w-full py-2 px-3 text-gray-700 leading-tight focus:outline-none focus:shadow-outline"
        id="username"
        type="text"
        placeholder="Username"
      />
    </div>
    <div class="mb-6">
      <label class="block text-gray-700 font-bold mb-2" for="password">
        Password
      </label>
      <input
        class="appearance-none border rounded w-full py-2 px-3 text-gray-700 leading-tight focus:outline-none focus:shadow-outline"
        id="password"
        type="password"
        placeholder="Password"
      />
    </div>
    <div class="flex items-center justify-between">
      <button
        class="bg-blue-500 hover:bg-blue-700 text-white font-bold py-2 px-4 rounded focus:outline-none focus:shadow-outline"
        type="button"
      >
        Sign In
      </button>
      <a
        class="inline-block align-baseline font-bold text-sm text-blue-500 hover:text-blue-800"
        href="#"
      >
        Forgot Password?
      </a>
    </div>
  </form>
</div>

In this example, we have a div element that centers the Form Login UI component on the screen. Inside the div, we have a form element that contains the input fields for the username and password, as well as the submit button and the link to reset the password.

Step 2: Style the Form Login UI component with Tailwind CSS

Now that we have the HTML structure set up, we can style the Form Login UI component using Tailwind CSS. Here is an example:

/* Center the Form Login UI component on the screen */
.flex {
  display: flex;
}

.justify-center {
  justify-content: center;
}

.items-center {
  align-items: center;
}

/* Style the Form Login UI component */
.bg-white {
  background-color: #fff;
}

.p-6 {
  padding: 1.5rem;
}

.rounded {
  border-radius: 0.25rem;
}

.shadow-md {
  box-shadow: 0 4px 6px -1px rgba(0, 0, 0, 0.1),
    0 2px 4px -1px rgba(0, 0, 0, 0.06);
}

.text-2xl {
  font-size: 1.5rem;
  line-height: 2rem;
}

.font-bold {
  font-weight: 700;
}

.mb-6 {
  margin-bottom: 1.5rem;
}

.block {
  display: block;
}

.text-gray-700 {
  color: #4a5568;
}

.mb-2 {
  margin-bottom: 0.5rem;
}

.appearance-none {
  -webkit-appearance: none;
  -moz-appearance: none;
  appearance: none;
}

.border {
  border-width: 1px;
}

.py-2 {
  padding-top: 0.5rem;
  padding-bottom: 0.5rem;
}

.px-3 {
  padding-left: 0.75rem;
  padding-right: 0.75rem;
}

.leading-tight {
  line-height: 1.25;
}

.focus\:outline-none:focus {
  outline: none;
}

.focus\:shadow-outline:focus {
  box-shadow: 0 0 0 3px rgba(66, 153, 225, 0.5);
}

.flex {
  display: flex;
}

.items-center {
  align-items: center;
}

.justify-between {
  justify-content: space-between;
}

.bg-blue-500 {
  background-color: #4299e1;
}

.hover\:bg-blue-700:hover {
  background-color: #2b6cb0;
}

.text-white {
  color: #fff;
}

.font-bold {
  font-weight: 700;
}

.py-2 {
  padding-top: 0.5rem;
  padding-bottom: 0.5rem;
}

.px-4 {
  padding-left: 1rem;
  padding-right: 1rem;
}

.rounded {
  border-radius: 0.25rem;
}

.focus\:outline-none:focus {
  outline: none;
}

.focus\:shadow-outline:focus {
  box-shadow: 0 0 0 3px rgba(66, 153, 225, 0.5);
}

.inline-block {
  display: inline-block;
}

.align-baseline {
  vertical-align: baseline;
}

.text-sm {
  font-size: 0.875rem;
  line-height: 1.25rem;
}

.text-blue-500 {
  color: #4299e1;
}

.hover\:text-blue-800:hover {
  color: #2b6cb0;
}

In this example, we have defined a set of CSS classes that correspond to the HTML elements in the Form Login UI component. We have used Tailwind CSS's pre-defined CSS classes to style the UI component quickly.

Step 3: Add interactivity with JavaScript

Finally, we can add interactivity to the Form Login UI component using JavaScript. Here is an example:

const form = document.querySelector("form");
const usernameInput = document.getElementById("username");
const passwordInput = document.getElementById("password");

form.addEventListener("submit", (event) => {
  event.preventDefault();

  const username = usernameInput.value;
  const password = passwordInput.value;

  // TODO: Validate the username and password

  console.log(`Username: ${username}`);
  console.log(`Password: ${password}`);
});

In this example, we have added an event listener to the form element that listens for the submit event. When the form is submitted, we prevent the default behavior, which is to reload the page. We then retrieve the values of the username and password input fields and log them to the console. You can add your own validation logic to the TODO section.
