I have looked at several other questions but I can't seem to figure any of them out, so here is my problem: I would like to have a div or a span, when you hover over it an area would appear and would be like a drop down.
Such as I have an div, and I want to hover over it and have it show some info about the item I hovered over
<html>
<head>
<title>Question1</title>
<styles type="css/text">
#cheetah {
background-color: red;
color: yellow;
text-align: center;
}
a {
color: blue;
}
#hidden {
background-color: black;
}
a:hover > #hidden {
background-color: orange;
color: orange;
}
</styles>
</head>
<body>
<div id="cheetah">
<p>Cheetah</p>
</div>
<div id="hidden">
<p>A cheetah is a land mammal that can run up 2 60mph!!!</p>
</div>
</body>
</html>
But this ^ doesn't seem to work, I don't know why... and if there is a way to do that in CSS, I would like to know, but I want any and all suggestions.
You can achieve this in CSS only if the hidden div is a child of the element you use for hovering:
http://jsfiddle.net/LgKkU/
You cannot affect a non-child element using :hover from within CSS2, which is supported by all common browsers.
You can affect a sibling element using CSS2.1 selectors, like so:
a:hover + .sibling { ... }
However, this only works for direct siblings. This means you could have HTML like this:
<p>Cheetah <span class="sibling">Blah Blah Blah</span></p>
Notice that the a and the span are direct siblings.
Here's a fiddle showing the siblings working: http://jsfiddle.net/vUUxp/
However, not all browsers support the CSS2.1 sibling selectors, so you need to decide based on your target audience if you can use this or not.
Edit: Corrected my mistake on the CSS version for the + selector: it's 2.1 that defines it, not CSS3. I also added a link showing browser support. Otherwise, the answer is the same.
Or, if you're open to it, use jQuery.
Something like this would work:
$("#element") // select your element (supports CSS selectors)
.hover(function(){ // trigger the mouseover event
$("#otherElement") // select the element to show (can be anywhere)
.show(); // show the element
}, function(){ // trigger the mouseout event
$("#otherElement") // select the same element
.hide(); // hide it
});
And remember to wrap this in a DOM ready function ($(function(){...}); or $(document).ready(function(){...});).
You can absolutely do this in CSS3 now using the ~ adjacent sibling selector.
triggerSelector:hover ~ targetSelector {
display: block;
}
For example, if you want a tooltip to appear when hovering over an adjacent button:
.button:hover ~ .tooltip {
display: block;
}

I know that there does not exist a CSS parent selector, but is it possible to style a parenting element when hovering a child element without such a selector?
To give an example: consider a delete button that when hovered will highlight the element that is about to become deleted:
<div>
<p>Lorem ipsum ...</p>
<button>Delete</button>
</div>
By means of pure CSS, how to change the background color of this section when the mouse is over the button?
I know it is an old question, but I just managed to do so without a pseudo child (but a pseudo wrapper).
If you set the parent to be with no pointer-events, and then a child div with pointer-events set to auto, it works:)
Note that <img> tag (for example) doesn't do the trick.
Also remember to set pointer-events to auto for other children which have their own event listener, or otherwise they will lose their click functionality.
div.parent {
pointer-events: none;
}
div.child {
pointer-events: auto;
}
div.parent:hover {
background: yellow;
}
<div class="parent">
parent - you can hover over here and it won't trigger
<div class="child">hover over the child instead!</div>
</div>
Edit:
As Shadow Wizard kindly noted: it's worth to mention this won't work for IE10 and below. (Old versions of FF and Chrome too, see here)
Well, this question is asked many times before, and the short typical answer is: It cannot be done by pure CSS. It's in the name: Cascading Style Sheets only supports styling in cascading direction, not up.
But in most circumstances where this effect is wished, like in the given example, there still is the possibility to use these cascading characteristics to reach the desired effect. Consider this pseudo markup:
<parent>
<sibling></sibling>
<child></child>
</parent>
The trick is to give the sibling the same size and position as the parent and to style the sibling instead of the parent. This will look like the parent is styled!
Now, how to style the sibling?
When the child is hovered, the parent is too, but the sibling is not. The same goes for the sibling. This concludes in three possible CSS selector paths for styling the sibling:
parent sibling { }
parent sibling:hover { }
parent:hover sibling { }
These different paths allow for some nice possibilities. For instance, unleashing this trick on the example in the question results in this fiddle:
div {position: relative}
div:hover {background: salmon}
div p:hover {background: white}
div p {padding-bottom: 26px}
div button {position: absolute; bottom: 0}
Obviously, in most cases this trick depends on the use of absolute positioning to give the sibling the same size as the parent, ánd still let the child appear within the parent.
Sometimes it is necessary to use a more qualified selector path in order to select a specific element, as shown in this fiddle which implements the trick multiple times in a tree menu. Quite nice really.
Another, simpler "alternate" approach (to an old question)..
would be to place elements as siblings and use:
Adjacent Sibling Selector (+)
or
General Sibling Selector (~)
<div id="parent">
<!-- control should come before the target... think "cascading" ! -->
<button id="control">Hover Me!</button>
<div id="target">I'm hovered too!</div>
</div>
#parent {
position: relative;
height: 100px;
}
/* Move button control to bottom. */
#control {
position: absolute;
bottom: 0;
}
#control:hover ~ #target {
background: red;
}

there is no CSS selector for selecting a parent of a selected child.
you could do it with JavaScript
As mentioned previously "there is no CSS selector for selecting a parent of a selected child".
So you either:
use a CSS hack as described in NGLN's answer
use javascript - along with jQuery most likely
Here is the example for the javascript/jQuery solution
On the javascript side:
$('#my-id-selector-00').on('mouseover', function(){
$(this).parent().addClass('is-hover');
}).on('mouseout', function(){
$(this).parent().removeClass('is-hover');
})
And on the CSS side, you'd have something like this:
.is-hover {
background-color: red;
}
In 2022:
This can be now achieved with CSS only, using the :has pseudo-class and the following expression:
div:has(button:hover) {}
Here's a snippet showcasing the original proposition:
div:has(button:hover) {
background-color: cyan;
}
<div>
<p>Lorem ipsum ...</p>
<button>Delete</button>
</div>
See browser support here. At the time of writing, all major browser support it—except Firefox, which still has a flawed experimental implementation.
This solution depends fully on the design, but if you have a parent div that you want to change the background on when hovering a child you can try to mimic the parent with a ::after / ::before.
<div class="item">
design <span class="icon-cross">x</span>
</div>
CSS:
.item {
background: blue;
border-radius: 10px;
position: relative;
z-index: 1;
}
.item span.icon-cross:hover::after {
background: DodgerBlue;
border-radius: 10px;
display: block;
position: absolute;
z-index: -1;
top: 0;
left: 0;
right: 0;
bottom: 0;
content: "";
}

This is extremely easy to do in Sass! Don't delve into JavaScript for this. The & selector in sass does exactly this.

I have this in line:
<div class="blue-car">
Car
</div>
<div class="iColor">
Blue
<div>
.blue-car:hover { color: red; }
.iColor:hover { color: read; }
I would like to make when someone hover to Car div second div which iColor change css and when hover to iColor div blue-car change css.
ie. I hover to 'Car' , 'Blue' will change color to red and when I hover to 'Blue' , 'Car' will change color to red, I want to make people aware that this two link is related.
I would love to have this in css only. No jquery. I have tried many no achievement at this moment.
Let me clear this, here is an example on this site. You could see when you hover to a country map, css link on right side will change, and you could see when you hover to a country link, country map css will change. This means this two div work each other. How they do this on this site: http://www.avito.ru
To start, CSS does NOT have a previous sibling operator. The only siblings that can be selected are adjacent (using +) or general (using ~).
It is possible to achieve the effect that you are seeking using only HTML and CSS. Below is one solution: http://jsfiddle.net/KGabX/. Basically, the .area is displayed as a table, which makes it wrap around the link and the image. However, the link is positioned absolutely, which prevents it from being "included" in a territory wrapped by the .area. This way, the .area is wrapped only around the image. Then, hovering over the .area we highlight the link. And, by hovering over the link we highlight the image.
Markup:
<div class = "area">
Link
<img src = "http://placehold.it/100x100" />
</div>
Styles:
.area {
display: table;
position: relative;
}
.area:hover > a {
color: red;
}
.area > img {
cursor: pointer
}
.area > a {
position: absolute;
right: -50px;
top: 50%;
font: bold 15px/2 Sans-Serif;
color: #000;
text-decoration: none;
margin-top: -15px;
}
.area > a:hover {
color: initial;
text-decoration: underline;
}
.area > a:hover + img {
opacity: 0.5;
}
Although I could not interpret what you wrote very well, I immediately noticed a flaw in your css selector.
Change your code to this:
<style>
.blue-car:hover a { color: red; }
.iColor:hover a { color: red; }
</style>
What's different about it? iColor:hover a. Look at the a, anchor selector. It was added because your previous CSS was only selecting the div. In css the child element, in this case the anchor, will supersede it's parents. There's two ways you can approach this. The first, or make the anchor tags color in css inherit.
If this wasn't your problem I'll fix my answer.
I'm not quite sure what you're asking because your question is a bit unclear.
From what I can understand, your issue stems from the fact that you're referring to the color property of the div, rather than the color property of the link.
That's a simple fix: all you need to do is drill down through the div to the link.
.blue-car:hover a{
color: red;
}
.iColor:hover a{
color: red;
}
Demo
Keep in mind that this isn't the best way to do this unless you absolutely need to refer to the links within the context of the div. I understand that your question fits into a broader context within your code, but for the example you gave here, all you really need is this:
a:hover{
color: red;
}
Again, I realize that you may need to change the colors or be more specific, but there's probably a better way to do this, even if that's the case.
The issue with this particular implementation is that your div is larger than your link, and a hover on your div is what activates the color change, so you'll run into this issue:
Here is my code.
<div class="start">start</div>
<div>middle-1</div>
<div>middle-2</div>
<div>middle-3</div>
...................
...................
<div>middle-n</div>
<div class="end">end</div>
I want to apply css to all div's when mouse hover the first div with class start.
With the current HTML structure you can use couple of sibling selectors for this.
.start:hover ~ div {
color: red; /* styles you want to apply */
}
/* reset styles back for all other divs after .end */
.start:hover ~ .end ~ div {
color: inherit;
}
Demo: http://jsfiddle.net/3c6V6/1/
However I would recommend to change HTML structure if you can. For example:
<div class="start">start</div>
<div class="middles">
<div>middle-1</div>
<div>middle-2</div>
<div>middle-3</div>
<div>middle-n</div>
<div class="end">end</div>
</div>
<div>after-1</div>
<div>after-2</div>
and CSS:
.start:hover + .middles > div {
color: red;
}
You would just have much more flexibility.
Demo: http://jsfiddle.net/3c6V6/2/
Could it be as simple as putting a parent container around it, and putting the hover on that, or do you wish to single out some of the siblings directly?
In this case, try putting :hover on the parent container like this:
.parent:hover div {/*style*/}
This is for your second version found in the comments: JSFiddle DEMO
div.start:hover~div.middles div:not(.end) {
font-weight: bold;
}
(This is for your original question):
div.start:hover~div:not(.end) {
font-weight: bold;
}
JSFiddle DEMO
This is where I found the information to do it. Didn't know there were so many CSS selectors.
Alright so i wanted to know how i can select multiple items on hover for example when i hover on list a Highlight a and on list b, give that list box shadow. ive tried to code it but for some reason im not able to do the multiple hover effect.
CSS Code:
#a:hover ~ #b {
background: #ccc
}
HTML Code:
<div><ul id="a"><li>Div A</li></ul></div>
<div>random elements</div>
<div>random elements</div>
<div>random elements</div>
<div><ul id="b"><li>Div B</li></ul></div>
The tilde ~ is for siblings.
But #b is not a sibling for #a
Change the id and it will work : (http://jsbin.com/AxUzOX/1/edit)
<div id="a">
<ul >
<li>Div A</li>
</ul>
</div>
<div>
random elements
</div>
<div>
random elements
</div>
<div>
random elements
</div>
<div id="b">
<ul >
<li>Div B</li>
</ul>
</div>
here is the jquery solution if you want http://jsbin.com/AxUzOX/4/edit
This is the jquery I have used
$('#a').hover(function(){
$('#a').css('background','#ccc');
$('#b').css('background','#ccc');
}, function(){
$('#a').css('background','#fff'); // Background of #a by default
$('#b').css('background','#fff'); // Background of #b by default
})
$('#b').hover(function(){
$('#a').css('background','#ccc');
$('#b').css('background','#ccc');
}, function(){
$('#a').css('background','#fff'); // Background of #a by default
$('#b').css('background','#fff'); // Background of #b by default
})
If you are changing the background of #a or #b,
specify the color to the places I had mentioned too. Simple :)
You should actually mention some class name or id name to the parent div which has the ul #a but as you don't want to assign it, you can use :first-child as shown below:
#a:hover {
background: #ccc
}
div:first-child:hover ~ div>ul#b{
color: red;
}
As you can see, I am hovering on the first child of div instead of ul because hovering on ul is same as hovering on parent div in your case.
I have did this way because there is no parent selector available in css not even in css3/css4.
Working Fiddle
Updated
for your previous sibling selector issue, use jquery
$('#b').hover(function() { $('#a').css('color','blue'); });
The other things you can do using just css as usual :)
If you add a wrapper div, you can accomplish it without any js.
The only issue with your example is the middle <div> that don't have any effects applied, so the jsfiddle solution will look a tad odd, but play with the effects and it might be what you want.
The idea is that you will hover the parent and apply a style to both, then when ALSO hovering over the child, apply different styles to that child.
Also try to not use ids if possible, they restrict you more than you often need.
.parent:hover .list-a, .parent:hover .list-b {
box-shadow: 3px 3px 5px 6px #ccc;
}
.parent .list-a:hover {
box-shadow: none;
background:#aaa;
}
.parent .list-b:hover {
box-shadow: none;
background:#4c4;
}
http://jsfiddle.net/tHTN4/
Now let's re-edit the jQuery part. Since you don't know any jQuery, or the knowledge isn't large. jQuery (a tool on top of Javascript) just helps you manipulate the HTML (DOM) in easy and efficient ways. To help you not edit css in multiple places, use the addClass and removeClass functions:
$(function(){
$('#a').hover(function(){
$('#a').addClass('.list-one-effect');
$('#b').addClass('.list-two-effect');
}, function(){
$('#a').removeClass('.list-one-effect');
$('#b').removeClass('.list-two-effect');
})
});
Once you remove the class, it will automatically revert to the original state (or the last altered state! from other effects). There is also a toggleClass function in jQuery, but I'd recommend you don't use that, as the above will always tell you what state you are in when. For completeness, this is wrapped in $(function(){}), which is one common way to make sure you have loaded jQuery AND the page is ready to run this code.
I want to change another element property on hover of a element. So far I've I came up with the following CSS:
#test3:hover #test4
{
background-color: red;
}
<div id="test3">three</div>
<div id="test4">four</div>
However, this is not working. Is this possible at all? What would you suggest?
#test3:hover #test4
This means, target an element test4 that is a child of test3. You want the + sibling selector instead:
#test3:hover + #test4
{
background-color: red;
}
