HTML-CSS: Zoom in zoom out animation

HTML-CSS : Exercise-45 with Solution

Using HTML, CSS creates a zoom in zoom out animation.

  • Use @keyframes to define a three-step animation. At the start (0%) and end (100%), the element is its original size (scale(1 ,1)). Halfway through (50%) it's scaled up to 1.5 times its original size (scale(1.5, 1.5)).
  • Use width and height to give the element a specific size.
  • Use animation to set the appropriate values for the element to make it animated.

HTML Code:

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width">
  <title>Using HTML, CSS creates a zoom in zoom out animation</title>
</head>
<body>
<div class="zoom-in-out-box">w3r</div>
</body>
</html>

CSS Code:

.zoom-in-out-box {
  margin: 24px;
  width: 50px;
  height: 50px;
  background: #f500cc;
  animation: zoom-in-zoom-out 1s ease infinite;
}

@keyframes zoom-in-zoom-out {
  0% {
    transform: scale(1, 1);
  }
  50% {
    transform: scale(1.5, 1.5);
  }
  100% {
    transform: scale(1, 1);
  }
}

HTML-CSS: Tips of the Day

How to show multiline text in a table cell?

You want to use the CSS white-space:pre applied to the appropriate <td>. To do this to all table cells, for example:

td { white-space:pre } 

Alternatively, if you can change your markup, you can use a <pre> tag around your content. By default web browsers use their user-agent stylesheet to apply the same white-space:pre rule to this element.

The PRE element tells visual user agents that the enclosed text is "preformatted". When handling preformatted text, visual user agents:

  • May leave white space intact.
  • May render text with a fixed-pitch font.
  • May disable automatic word wrap.
  • Must not disable bidirectional processing.
