How Can I Create Hover-Activated Tooltips for Div Elements with Fade-in/Fade-out Effects?

Enhance Div Interactivity with Hover-Activated Tooltips

Displaying relevant information or guidance on a web page can enhance user experience. In this case, we seek to add a tooltip to a div element that appears when the user hovers over it, with a smooth fade in/out effect. Here's how it can be achieved:

The basic tooltip functionality can be achieved by adding a title attribute to the div element. This displays a simple tooltip when the cursor hovers over the element. For example:

<div title="This is my tooltip">
<p>In addition to the basic tooltip, CSS properties can be incorporated to create a more dynamic effect:</p>
<p><strong>CSS for Fade-in/Fade-out Animation</strong></p>
<p>To add a fade in/out effect, CSS can be used to animate the appearance and disappearance of the tooltip:</p>
<pre class="brush:php;toolbar:false">.visible {
  height: 3em;
  width: 10em;
  background: yellow;
}

<div title="This is my tooltip" class="visible"></div>
