In this article, we will create a form with a glassmorphic design. A modern effect guaranteed!

Step 1

Let's start with the HTML code.

HTML

<div class="container">
  <form >
    <p>Welcome</p>
    <input type="email" placeholder="Email"><br>
    <input type="password" placeholder="Password"><br>
    <input type="button" value="Login"><br>
    <a href="#">Forgot Password</a>
  </form>

  <div class="drop drop-1"></div>
  <div class="drop drop-2"></div>
  <div class="drop drop-3"></div>
  <div class="drop drop-4"></div>
  <div class="drop drop-5"></div>
</div>

Step 2

Let's move on to the design of our form page.

CSS

body {
  background: linear-gradient(45deg, #FC466B, #3F5EFB);
  height: 100vh;
  font-family: arial, sans-serif;
  display: flex;
  align-items: center;
  justify-content: center;
}

.container {
  position: relative;
}

So far, we are only centering our form using Flexbox.

The drop classes will allow us to display small transparent clouds around our form.

Step 3

Now it's the form's turn.

CSS

form {
  background: rgba(255, 255, 255, .3);
  padding: 3rem;
  height: 320px;
  border-radius: 20px;
  border-left: 1px solid rgba(255, 255, 255, .3);
  border-top: 1px solid rgba(255, 255, 255, .3);
  backdrop-filter: blur(10px);
  -webkit-backdrop-filter: blur(10px);
  -moz-backdrop-filter: blur(10px);
  box-shadow: 20px 20px 40px -6px rgba(0, 0, 0, .2);
  text-align: center;
}

Step 4

Let's now style the texts.

CSS

p {
  color: white;
  font-weight: 500;
  opacity: .7;
  font-size: 1.4rem;
  margin-bottom: 60px;
  text-shadow: 2px 2px 4px rgba(0, 0, 0, .2);
}
  
a {
  text-decoration: none;
  color: #ddd;
  font-size: 12px;
}

a:hover {
  text-shadow: 2px 2px 6px #00000040;
}

a:active {
  text-shadow: none;
}

Step 5

Let's move on to the inputs.

CSS

input {
  background: transparent;
  border: none;
  border-left: 1px solid rgba(255, 255, 255, .3);
  border-top: 1px solid rgba(255, 255, 255, .3);
  padding: 1rem;
  width: 200px;
  border-radius: 50px;
  backdrop-filter: blur(5px);
  -webkit-backdrop-filter: blur(5px);
  -moz-backdrop-filter: blur(5px);
  box-shadow: 4px 4px 60px rgba(0, 0, 0, .2);
  color: white;
  font-weight: 500;
  text-shadow: 2px 2px 4px rgba(0, 0, 0, .2);
  transition: all .3s;
  margin-bottom: 2em;
}

Step 6

Let's style the interactions.

CSS

input:hover,
input[type="email"]:focus,
input[type="password"]:focus{
  background: rgba(255,255,255,0.1);
  box-shadow: 4px 4px 60px 8px rgba(0,0,0,0.2);
}
    
input[type="button"] {
  margin-top: 10px;
  width: 150px;
  font-size: 1rem;
  cursor: pointer;
}

::placeholder {
  color: #fff;
}

Step 7

Let's handle the shadows.

CSS

.drop {
  background: rgba(255, 255, 255, .3);
  backdrop-filter: blur(10px);
  -webkit-backdrop-filter: blur(10px);
  border-radius: 10px;
  border-left: 1px solid rgba(255, 255, 255, .3);
  border-top: 1px solid rgba(255, 255, 255, .3);
  box-shadow: 10px 10px 60px -8px rgba(0,0,0,0.2);
  position: absolute;
  transition: all 0.2s ease;
}

Step 8

Let's finish our form by styling each shadow one by one.

CSS

.drop-1 {
  height: 80px; width: 80px;
  top: -20px; left: -40px;
  z-index: -1;
}

.drop-2 {
  height: 80px; width: 80px;
  bottom: -30px; right: -10px;
}

.drop-3 {
  height: 100px; width: 100px;
  bottom: 120px; right: -50px;
  z-index: -1;
}

.drop-4 {
  height: 120px; width: 120px;
  top: -60px; right: -60px;
}

.drop-5 {
  height: 60px; width: 60px;
  bottom: 170px; left: 90px;
  z-index: -1;
}
