Tips and methods to achieve the floating label effect with CSS

In web design, the floating label effect is a common and commonly used interactive effect. It can display more information or functions when the user hovers the mouse over an element, providing a better user experience. This article will introduce some CSS techniques and methods to achieve the floating label effect, and provide specific code examples.

1. Basic floating label effect
The basic floating label effect can be achieved by setting the :hover pseudo-class of the element. The following is a simple example:

HTML code:

<div class="container">
  <div class="element">悬浮标签</div>
  <div class="tooltip">这是一个悬浮标签</div>
</div>

CSS code:

.container {
  position: relative;
  width: 200px;
  height: 200px;
  border: 1px solid #ccc;
}

.element {
  width: 100px;
  height: 50px;
  background-color: #f00;
  color: #fff;
  text-align: center;
  line-height: 50px;
}

.tooltip {
  display: none;
  position: absolute;
  top: 50px;
  left: 0;
  width: 200px;
  padding: 10px;
  background-color: #000;
  color: #fff;
}

.element:hover + .tooltip {
  display: block;
}

In the above code, .container is a wrapping element, and .element is to be implemented The target element of the floating label effect, .tooltip is the label content to be displayed. Using the :hover pseudo-class and the selector, when the mouse hovers over the .element, the display property of the .tooltip is set to block, thereby displaying it.

2. Animated floating label effect
If you want a smoother and more elegant effect, you can add some animation effects to the floating label, such as gradient display and disappearance. The following is an example of implementing an animated floating label effect:

HTML code:

<div class="container">
  <div class="element">悬浮标签</div>
  <div class="tooltip">这是一个悬浮标签</div>
</div>

CSS code:

.container {
  position: relative;
  width: 200px;
  height: 200px;
  border: 1px solid #ccc;
}

.element {
  width: 100px;
  height: 50px;
  background-color: #f00;
  color: #fff;
  text-align: center;
  line-height: 50px;
}

.tooltip {
  display: none;
  position: absolute;
  top: 50px;
  left: 0;
  width: 200px;
  padding: 10px;
  background-color: #000;
  color: #fff;
  opacity: 0;
  transition: opacity 0.3s;
}

.element:hover + .tooltip {
  display: block;
  opacity: 1;
}

In the above code, by setting the .tooltip element The opacity attribute and transition effect allow the label to present a gradient animation effect when it appears and disappears.

3. Multiple floating label effects
Sometimes, there may be multiple elements on the page that need to achieve the floating label effect. To avoid conflicts, you can use CSS class selectors to distinguish different floating labels. The following is an example to achieve the effect of multiple floating labels:

HTML code:

<div class="container">
  <div class="element">悬浮标签1</div>
  <div class="tooltip">这是一个悬浮标签1</div>
</div>
<div class="container">
  <div class="element">悬浮标签2</div>
  <div class="tooltip">这是一个悬浮标签2</div>
</div>
</div>
</div>

CSS code:

.container {
  position: relative;
  width: 200px;
  height: 200px;
  border: 1px solid #ccc;
}

.element {
  width: 100px;
  height: 50px;
  background-color: #f00;
  color: #fff;
  text-align: center;
  line-height: 50px;
}

.tooltip {
  display: none;
  position: absolute;
  top: 50px;
  left: 0;
  width: 200px;
  padding: 10px;
  background-color: #000;
  color: #fff;
}

.element:hover + .tooltip {
  display: block;
}

In the above code, by giving each floating label The .container element adds different classes to distinguish different floating labels to avoid conflicts.

Summary: The floating label effect using CSS is a commonly used interactive effect. You can achieve basic effects by setting :hover pseudo-classes and transition effects, and you can also add animation effects to enhance the user experience.
