When hovering, apply style 1 to all elements with the same id, and style 2 to the hovered element

I'm working with some user-generated divs that I want to dynamically highlight when hovered over, while simultaneously blurring the other divs.

My challenge is figuring out how to change the style of the hovered div separately from all the others. The divs are generated using PHP and have a basic structure like this:

<div class="usercontainer" id="usercontainer"></div>

I've attempted applying a hover effect to the div the user is hovering on, but I'm struggling to apply a different effect to the rest of the divs at the same time. Do I need to use JavaScript for this, or is it achievable with CSS alone?

.usercontainer:hover {
   background-color: red;
   opacity: 1.0;  
}

Answer №1

In this explanation, I will focus on the CSS method exclusively, even though you have the option to achieve it by assigning a class to the parent element using JavaScript.

An inconvenience of following this approach is that you may need to use !important to override styles applied to child elements.

.children {
    display: inline-block;
    height: 100px;
    width: 100px;
    background-color: grey;
    color: red;
    font-size: 50px;
    border: solid 1px yellow;
}

.parent:hover .children {
    opacity: 0.2;
}

.children:hover {
    opacity: 1 !important;
}
<div class="parent">
    <div class="children">1</div>
    <div class="children">2</div>
    <div class="children">3</div>
    <div class="children">4</div>
</div>
