I have the following code:

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">

            <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>

So what I am basically looking for is the shake effect when the user submits without entering any inputs.

Expected Output

When the user hits the submit button without entering anything, the border of the box should turn red as well as shake. I just want the boxes of the placeholders to shake and turn red, not the whole element. I tried adding keyframes to make this possible but got stuck since I was not getting the desired output, any suggestions?

In other words, I just would like the first name, last name, email, and subject borders of the boxes to turn red and shake.

Add an event listener for submit that loops through all the input and textarea fields and checks whether they are valid with checkValidity(). If they are not valid, we set their border color to red with the borderColor style attribute and set their animation with the animation style attribute.

To be able to play the same animation over and over again, we can use setTimeout to wait a specified number of milliseconds and then set the animation style attribute back to unset.

document.querySelector('form').addEventListener('submit', function(e) {
  var isValid = true;
  this.querySelectorAll('input, textarea').forEach(function(f) {
    if (!f.checkValidity()) {
      isValid = false;
      f.style.borderColor = "red";
      f.style.animation = "shake 0.82s forwards";
      setTimeout(function(){f.style.animation="unset";},820);
    }else{
      f.style.borderColor = "initial";
      //Sets it back to normal if the field is valid
    }
  })
  if (!isValid) {
    e.preventDefault();
  }
})
