Changing the child element's CSS when the parent is hovered

Question

First of all, I'm assuming this is too complex for CSS3, but if there's a solution in there somewhere, I'd love to go with that instead.

The HTML is pretty straightforward.

<div class="parent">
    <div class="child">
        Text Block 1
    </div>
</div>

<div class="parent">
    <div class="child">
        Text Block 2
    </div>
</div>

The child div is set to display:none; by default, but then changes to display:block; when the mouse is hovered over the parent div. The problem is that this markup appears in several places on my site, and I only want the child to be displayed if the mouse is over it's parent, and not if the mouse is over any of the other parents (they all have the same class name and no IDs).

I've tried using $(this) and .children() to no avail.

$('.parent').hover(function(){
            $(this).children('.child').css("display","block");
        }, function() {
            $(this).children('.child').css("display","none");
        });

Solution 1

Why not just use CSS?

.parent:hover .child, .parent.hover .child { display: block; }

and then add JS for IE6 (inside a conditional comment for instance) which doesn't support :hover properly:

jQuery('.parent').hover(function () {
    jQuery(this).addClass('hover');
}, function () {
    jQuery(this).removeClass('hover');
});

Here's a quick example: Fiddle

Solution 2

No need to use the JavaScript or jquery, CSS is enough:

.child{ display:none; }
.parent:hover .child{ display:block; }

SEE DEMO

Solution 3

.parent:hover > .child {
    /*do anything with this child*/
}

Solution 4

Use toggleClass().

$('.parent').hover(function(){
$(this).find('.child').toggleClass('color')
});

where color is the class. You can style the class as you like to achieve the behavior you want. The example demonstrates how class is added and removed upon mouse in and out.

Solution 5

Not sure if there's terrible reasons to do this or not, but it seems to work with me on the latest version of Chrome/Firefox without any visible performance problems with quite a lot of elements on the page.

*:not(:hover)>.parent-hover-show{
    display:none;
}

But this way, all you need is to apply parent-hover-show to an element and the rest is taken care of, and you can keep whatever default display type you want without it always being "block" or making multiple classes for each type.

that code isn't working for me. is it supposed to say ".parent.hover" and not ".parent:hover"?? case i've never seen what you have before. and doesn't a comma indicate multiple selectors taking the same styles? i don't see how that helps here. a little more info on that CSS, por favor 0=]

:hover is one of the "Dynamic pseudo-classes" defined by CSS2 (here's the spec). Here's a quick example: http://jsfiddle.net/5FLr4/. it works for me.

ahh thanks so much! i actually had some relative positioning that was pushing the child text out of view... doh! >.< i appreciate the help!

Apparently this won't work for .child::-webkit-scrollbar-thumb if you want to change the highlight of the scrollbar inside the child element.

.parent:not(:hover) .child { display: none; } seems to work well for me, though I'm certainly not worried about IE6. But this way I can use it on elements that I don't want to have a uniform display property.

This doesn't do what the question asked. It changes the border around the element that is hovered over. Not the border around a child element.

[Marek Barta]

It does exactly what I'm looking for except its chaging all the child elements not only the one which is hovered over

[Henrique Donati]

@MarekBarta why don't you just use the :hover on the child element then? What you are seeing is what was asked!
