My divs are not appearing

Shreyas Sreenivasa

My #abhimanyu, #arjun, #bheem and #eklavya divs are are not appearing. Right now the unit is percentage but if I put pixels it works but it wont be responsive. Any idea why its not appearing? Thank you in advance!

Update: One more problem, on the phone when i type in the text box everything goes out of their place.

Here's my code:

function displaySignInError() {
  var schoolName = document.getElementById('schoolNameBox').value.toLowerCase();
  switch (schoolName) {
    case 'new horizon gurukul':
      window.location = "NHGLogin.php";
      break;
    default:
      var schoolErrorMessage = document.getElementById('schoolErrorMessage');
      schoolErrorMessage.innerHTML = "Please Enter a valid school name, still if invalid schoold does not exist.";
      schoolErrorMessage.style.color = 'red';
      
  }
}

You need to define parent's height since you are using percentage.

What is better to do is:

Change your HTML to:

<div class="show-this">
    <div id="abhimanyu"></div>
    <div id="arjun"></div>
    <div id="bheem"></div>
    <div id="eklavya"></div>
</div>

On your css. Add this code:

.show-this {
    height: 100vh;
    width: 100vw;
}

Or you can just declare

body {
    height: 100vh; // or something
}

.show-this {
  width: 100vw;
  height: 100vh; }

.show-this #abhimanyu {
  height: 10%;
  width: 80%;
  background: red; }

.show-this #arjun {
  height: 20%;
  width: 90%;
  background: yellow; }

.show-this #bheem {
  height: 40%;
  width: 50%;
  background: green; }

.show-this #eklavya {
  height: 20%;
  width: 100%;
  background: blue; }
<div class="show-this">
  <div id="abhimanyu"></div>
  <div id="arjun"></div>
  <div id="bheem"></div>
  <div id="eklavya"></div>
</div>

Hope it helps! Cheers.
