Question

Hello I have the following contact form code:

 /* Contact Form */ input[type=text], [type=email], select, textarea { width: 100%; padding: 12px; border: 1px solid #555; margin-top: 6px; margin-bottom: 16px; resize: vertical; } input[type=submit] { background-color: #0563bb; color: white; padding: 12px 20px; border: none; cursor: pointer; } input[type=submit]:hover { opacity: 0.9; }.contactform { position: relative; border-radius: 50px; background-color: #f2f2f2; padding: 5px; z-index: 2; display: block; margin-left: auto; margin-right: auto; margin-bottom: auto; margin-top: 1%; width: 100%; animation-name: gradient; animation-duration: 3s; animation-iteration-count: infinite; }.contactform:hover { animation-name: gradient; animation-duration: 15s; animation-iteration-count: infinite; }.column { float: center; width: 50%; margin-top: 6px; padding: 20px; display: block; margin-left: auto; margin-right: auto; }.row:after { content: ""; display: table; clear: both; } @media screen and (max-width: 600px) {.column, input[type=submit] { width: auto; margin-top: 0; } } @keyframes shake { 10%, 90% { transform: translate3d(-1px, 0, 0); } 20%, 80% { transform: translate3d(2px, 0, 0); } 30%, 50%, 70% { transform: translate3d(-4px, 0, 0); } 40%, 60% { transform: translate3d(4px, 0, 0); } }

 <section id="contact"> <div class="container" data-aos="fade-up"> <div class="contactform"> <div style="text-align:center"> <div class="section-title"> <h2><br/>Get In Touch</h2> </div> <p>Feel Free To Reach Out To Me Through This Form. </p> </div> <div class="row"> <div class="column"> <form name="myform" action="thankyou.html" method="POST" novalidate> <label for="firstname">First Name</label> <input type="text" id="first name" name="firstname" placeholder="Your First Name.." required> <label for="lastname">Last Name</label> <input type="text" id="lastname" name="lastname" placeholder="Your Last Name.:" required> <label for="email">Email.</label> <input type="email" id="email" name="email" placeholder="Your Email.." required> <label for="subject">Subject</label> <textarea id="subject" name="subject" placeholder="Lets Collaborate.:" style="height:170px" required></textarea> <input type="submit" value="Submit"> </form> </div> </div> </div> </div> </section>

I want to modify this form a little bit, and only change the input fields. Basically, I would like to add animation on the input fields.

Expected Output

As you can see, I would like the message to be displayed in the input field, but then when the user clicks the input field, the message should display at the top of the input field as shown in the video. Any suggestions on how I can accomplish this task?

Here is the code of the contact form in the video:

Answer 1

I tried to create a Beta for you, using the video you linked as a reference

using HTML and CSS only...

the trick here is creating an Extra Div as a Parent, so we can put the label and input inside.

now set the parent to have a position: relative; so the label will be absolute

now successfully we can use TOP, LEFT, RIGHT, BOTTOM and that's it (position the label as the place-holder)

I put the logic here .input-container input:focus~label

 * { --input-height: 3rem; } section { height: 100vh; width: 100vw; display: grid; place-content: center; }.input-container input { height: var(--input-height); width: 80vw; font-size: 2rem; }.input-container { position: relative; display: grid; place-items: center start; }.input-container label { position: absolute; left: 1rem; font-size: 1.5rem; color: rgb(90, 90, 90); background-color: white; transition-duration: 0.5s; }.input-container input:focus~label { position: absolute; font-size: 0.7rem; top: -0.6rem; padding: 0.2em; left: 0.5rem; color: rgb(0, 81, 255); background-color: white; transition-duration: 0.2s; z-index: 2; }
