You can use an iframe to display a preview of the page on mouseover:
.box{
display: none;
width: 100%;
}
a:hover + .box,.box:hover{
display: block;
position: relative;
z-index: 100;
}
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.

.box{
display: none;
width: 100%;
}
a:hover + .box,.box:hover{
display: block;
position: relative;
z-index: 100;
}
Live previews for <a href="https://en.wikipedia.org/">Wikipedia</a>
<div class="box">
