Edited to fit OP’s request to change content of a singular box based on hover of other boxes. Using the general sibling combinator, we can select a div with the class results when a box is hovered.
HTML
<div class="container">
<div class="box1">1</div>
<div class="box2">2</div>
<div class="results"></div>
</div>
CSS
.box1, .box2 { display: inline-block; width: 100px; height: 100px; background: #ccc; }
.results {
width: 250px;
height: 100px;
background: #ccc;
margin-top: 4px;
}
.box1:hover ~ div.results:before {
cursor: pointer;
content: "Hello";
}
.box2:hover ~ div.results:before {
cursor: pointer;
content: "World";
}
