Here is the code snippet I am working with:
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;
}
} <section id="contact">

</section>I am aiming to implement a shake effect when the user submits the form without entering any details.
Desired Outcome
Upon clicking submit with empty fields, I want the borders of the input boxes to turn red and shake. Only the placeholder boxes should exhibit this behavior, not the entire element. I tried using keyframes but couldn't achieve the desired result. Any recommendations would be greatly appreciated!
In simpler terms, I specifically want the first name, last name, email, and subject input box borders to turn red and shake.
