Answer №1

Using CSS animations can help achieve a smooth effect.

If you wish to incorporate animations, it is recommended not to rely on display: none; for hiding elements as it only allows for them to be either entirely hidden or completely visible. Instead, consider using properties like height or opacity.

To manage visibility toggling, it is advisable to toggle a pre-defined class containing the styles for the visible state rather than directly modifying styles in the script. This approach enhances maintainability and facilitates the addition of more visual effects.

function toggleVisibility() {
  document.getElementById("myElement").classList.toggle("visible")
}

body {
  background-color: #f4f4f4;
}

.visible {
  height: 150px;
  opacity: 1;
}

div {
  background-color: coral;
  height: 0;
  opacity: 0;
  margin: 15px;
  transition: all 0.5s;
}

button {
  color: white;
  font-weight: bold;
  background-color: teal;
  padding: 5px 15px;
  font-size: 1rem;
}

<div id="myElement">
</div>
<button type="button" onclick=toggleVisibility()>TOGGLE VISIBILITY</button>

One clever solution involves utilizing the CSS property opacity. This method not only achieves the desired effect but also prevents any content shifting, such as in the case of a button changing position.

function revealContent(){
      document.getElementById("hiddenContent").classList.add('show');
    }

body{
      background: black;
    }
    div{
      background : red;
      height: 200px;
      margin : 20px 100px;
      width : auto;
      //display: none;
      opacity:0;
      transition:opacity.3s;
    }
    .show{
      opacity:1;
    }
    button{
      color: red;
      font-weight:bold;
      background : grey;
      padding : 5px 20px;
      font-size : 1rem;
    }

Would you prefer a gradual fade-in effect? If yes, consider using opacity instead of display and gradually increase it using a CSS animation. You can find a tutorial here.

Answer №4

Enhance your website with css animations and keyframes by following these steps:

  animation-name: example; animation-duration: 2s;

To define the animation behavior, include the following code within your style tag:

 @keyframes example {0%   {opacity: 0; } 100% {opacity: 1;}}

<!DOCTYPE html>
<html lang="en" dir="ltr">
  <head>
    <meta charset="utf-8>
    <title>sample</title>
  </head>
  <style >
    body{
      background: black;
    }
    div{
      background : red;
      height: 200px;
      margin : 20px 100px;
      width : auto;
      display: none;
      animation-name: example;
  animation-duration: 2s;
    }

@keyframes example {
  0%   {opacity: 0; }
  100% {opacity: 1;}
}
    button{
      color: red;
      font-weight:bold;
      background : grey;
      padding : 5px 20px;
      font-size : 1rem;
    }
  </style>
  <body>
    <div id="myDIV">
    </div>
    <button type="button" onclick=myFunction() name="button">CLICK ME</button>
  </body>
  <script>
    function myFunction(){
      document.getElementById("myDIV").style.display = "block";

    div#myDIV {
      background: red !important;
      font-szie: 50px;
      background: red;
      height: 200px;
      margin: 20px 100px;
      width: auto;
      opacity: 0;
      transition: 1s opacity;
    }
    
    div.animate__fadeIn {
      opacity: 1 !important;
      transition: 1s opacity;
    }
    
    button {

      background: grey;
      padding: 5px 20px;
