HTML-CSS: Popout menu

HTML-CSS : Exercise-23 with Solution

Using HTML, CSS reveals an interactive popout menu on hover/focus.

  • Use left: 100% to move the popout menu to the right of the parent.
  • Use visibility: hidden to hide the popout menu initially, allowing for transitions to be applied (unlike display: none).
  • Use the :hover, :focus and :focus-within pseudo-class selectors to apply visibility: visible to the popout menu, displaying it when the parent element is hovered/focused.

HTML Code:

<!DOCTYPE html>

<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width">

</head>
<body>
<div class="reference" tabindex="0">
  <div class="popout-menu">w3resource Popout menu</div>
</div>
</body>
</html>

CSS Code:

.reference {
  position: relative;
  background: #CC56FF;
  width: 100px;
  height: 80px;
}

.popout-menu {
  position: absolute;
  visibility: hidden;
  left: 100%;
  background: #FF89CC;
  color: white;
  padding: 16px;
}

.reference:hover > .popout-menu,
.reference:focus > .popout-menu,
.reference:focus-within > .popout-menu {
  visibility: visible;
}

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.
