How to Create a Live Preview Popup on Mouseover for Linked Pages?

Displaying Live Preview on Mouseover with Linked Pages

In this article, we'll explore how to create a feature that displays a live preview of a linked page in a small popup when the user hovers over the link.

Similar to the functionality demonstrated on cssglobe.com, we aim to implement a popup that shows a live preview of the linked page on mouseover. However, in our case, we'll enhance it to display live content.

Solution

Utilizing an iframe, we can incorporate a live preview of the page on mouseover:

<code class="javascript">.box{
    display: none;
    width: 100%;
}

a:hover + .box,.box:hover{
    display: block;
    position: relative;
    z-index: 100;
}</code>

<code class="html">This live preview for <a href="https://en.wikipedia.org/">Wikipedia</a>
  <div class="box">
    <iframe src="https://en.wikipedia.org/" width = "500px" height = "500px">
    </iframe>
  </div> 
remains open on mouseover.</code>

In this solution, a hidden div is associated with each link, containing an iframe to display the live preview. When the user hovers over the link or the div, the div becomes visible, positioned relatively to the link, and appears on top of other elements thanks to the z-index.
