HTML-CSS: Sibling fade

HTML-CSS : Exercise-24 with Solution

Using HTML, CSS fades out the siblings of a hovered item.

  • Use a transition to animate changes to opacity.
  • Use the :hover and :not pseudo-class selectors to change the opacity of all elements except for the one the mouse is over to 0.5.

HTML Code:

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width">
  <title>Using HTML, CSS fades out the siblings of a hovered item</title>
</head>
<body>
<div class="sibling-fade">
  <span>Case 1</span> <span>Case 2</span> <span>Case 3</span>
  </div>
</body>
</html>

CSS Code:


span {
  padding: 0 16px;
  transition: opacity 0.3s;
}

.sibling-fade:hover span:not(:hover) {
  opacity: 0.5;
}

HTML-CSS: Tips of the Day

How to get CSS to select ID that begins with a string ?

[id^=product]

^= indicates "starts with". Conversely, $= indicates "ends with".

The symbols are actually borrowed from Regex syntax, where ^ and $ mean "start of string" and "end of string" respectively.
