I would like to show a div when someone hovers over an <a> element, but I would like to do this in CSS and not JavaScript. Do you know how this can be achieved?
You can do something like this:
div {
display: none;
}
a:hover + div {
display: block;
}
<a>Hover over me!</a>
<div>Stuff shown on hover</div>
This uses the adjacent sibling selector, and is the basis of the suckerfish dropdown menu.
HTML5 allows anchor elements to wrap almost anything, so in that case the div element can be made a child of the anchor. Otherwise the principle is the same - use the :hover pseudo-class to change the display property of another element.
.showme {
display: none;
}
.showhim:hover .showme {
display: block;
}
<div class="showhim">HOVER ME
<div class="showme">hai</div>
</div>
jsfiddle
Since this answer is popular I think a small explanation is needed. Using this method when you hover on the internal element, it wont disappear.
Because the .showme is inside .showhim it will not disappear when you move your mouse between the two lines of text (or whatever it is).
These are example of quirqs you need to take care of when implementing such behavior.
It all depends what you need this for. This method is better for a menu style scenario, while Yi Jiang's is better for tooltips.
I found using opacity is better, it allows you to add css3 transitions to make a nice finished hover effect. The transitions will just be dropped by older IE browsers, so it degrades gracefully to.
#stuff {
opacity: 0.0;
-webkit-transition: all 500ms ease-in-out;
-moz-transition: all 500ms ease-in-out;
-ms-transition: all 500ms ease-in-out;
-o-transition: all 500ms ease-in-out;
transition: all 500ms ease-in-out;
}
#hover {
width:80px;
height:20px;
background-color:green;
margin-bottom:15px;
}
#hover:hover + #stuff {
opacity: 1.0;
}
<div id="hover">Hover</div>
<div id="stuff">stuff</div>
I'm by no means an expert, but I'm incredibly proud of myself for having worked something out about this code. If you do:
div {
display: none;
}
a:hover > div {
display: block;
}
Note the >, a direct child selector.
You can contain the whole thing in an a tag, then, as long as your trigger (which can be in it's own div, or straight up in the a tag, or anything you want) is physically touching the revealed div, you can move your mouse from one to the other.
Maybe this isn't useful for a great deal, but I had to set my revealed div to overflow: auto, so sometimes it had scroll bars, which couldn't be used as soon as you move away from the div.
In fact, after finally working out how to make the revealed div, (although it is now a child of the trigger, not a sibling), sit behind the trigger, in terms of z-index, (with a little help from this page: How to get a parent element to appear above child) you don't even have to roll over the revealed div to scroll it, just stay hovering over the trigger and use your wheel, or whatever.
My revealed div covers most of the page, so this technique makes it a lot more permanent, rather than the screen flashing from one state to another with every move of the mouse. It's really intuitive actually, hence why I'm really quite proud of myself.
The only downside is that you can't put links within the whole thing, but you can use the whole thing as one big link.
This answer doesn't require that you know the what type of display (inline, etc.) the hideable element is supposed to be when being shown:
.hoverable:not(:hover) + .show-on-hover {
display: none;
}
<a class="hoverable">Hover over me!</a>
<div class="show-on-hover">I'm a block element.</div>
<hr />
<a class="hoverable">Hover over me also!</a>
<span class="show-on-hover">I'm an inline element.</span>
This uses the adjacent sibling selector and the not selector.
I would like to offer this general purpose template solution that expands on the correct solution provided by Yi Jiang's.
The additional benefits include:
support for hovering over any element type, or multiple elements;
the popup can be any element type or set of elements, including objects;
self-documenting code;
ensures the pop-up appears over the other elements;
a sound basis to follow if you are generating html code from a database.
In the html you place the following structure:
<div class="information_popup_container">
<div class="information">
<!-- The thing or things you want to hover over go here such as images, tables,
paragraphs, objects other divisions etc. -->
</div>
<div class="popup_information">
<!-- The thing or things you want to popup go here such as images, tables,
paragraphs, objects other divisions etc. -->
</div>
</div>
In the css you place the following structure:
div.information_popup_container {
position: absolute;
width:0px;
height:0px;
/* Position Information */
/* Appearance Information */
}
div.information_popup_container > div.information {
/* Position Information */
/* Appearance Information */
}
div.information_popup_container > div.popup_information {
position: fixed;
visibility: hidden;
/* Position Information */
/* Appearance Information */
}
div.information_popup_container > div.information:hover + div.popup_information {
visibility: visible;
z-index: 200;
}
A few points to note are:
Because the position of the div.popup is set to fixed (would also work with absolute) the content is not inside the normal flow of the document which allows the visible attribute to work well.
z-index is set to ensure that the div.popup appears above the other page elements.
The information_popup_container is set to a small size and thus cannot be hovered over.
This code only supports hovering over the div.information element. To support hovering over both the div.information and div.popup then see Hover Over The Popup below.
It has been tested and works as expected in Opera 12.16 Internet Explorer 10.0.9200, Firefox 18.0 and Google Chrome 28.0.15.
Hover Over The Popup
As additional information. When the popup contains information that you might want to cut and paste or contains an object that you might want to interact with then first replace:
div.information_popup_container > div.information:hover + div.popup_information {
visibility: visible;
z-index: 200;
}
with
div.information_popup_container > div.information:hover + div.popup_information
,div.information_popup_container > div.popup_information:hover {
visibility: visible;
z-index: 200;
}
And second, adjust the position of div.popup so that there is an overlap with div.information. A few pixels is sufficient to ensure that the div.popup is can receive the hover when moving the cusor off div.information.
This does not work as expected with Internet Explorer 10.0.9200 and does work as expected with Opera 12.16, Firefox 18.0 and Google Chrome 28.0.15.
See fiddle http://jsfiddle.net/F68Le/ for a complete example with a popup multilevel menu.
The + allow 'select' only first not nested element , the > select nested elements only - the better is to use ~ which allow to select arbitrary element which is child of parent hovered element. Using opacity/width and transition you can provide smooth appear
div { transition: all 1s }
.ccc, .ggg { opacity: 0; color: red}
.ccc { height: 0 }
.aaa:hover ~ .bbb .ccc { opacity: 1; height: 34px }
.aaa:hover ~ .eee .fff .ggg { opacity: 1 }
<div class="aaa">Hover me... to see<br><br> </div>
<div class='bbb'>BBBBB
<div class='ccc'>CCCCC
<div class='ddd'>DDDDD</div>
</div>
</div>
<div class='eee'>EEEEE
<div class='fff'>FFFFF
<div class='ggg'>GGGGG</div>
<div class='hhh'>HHHHH</div>

Based on the main answer, this is an example, useful to display an information tooltip when clicking on a ? near a link:
document.onclick = function() { document.getElementById("tooltip").style.display = 'none'; };
document.getElementById("tooltip").onclick = function(e) { e.stopPropagation(); }
document.getElementById("help").onclick = function(e) { document.getElementById("tooltip").style.display = 'block';
e.stopPropagation(); };
#help { opacity: 0; margin-left: 0.1em; padding: 0.4em; }
a:hover + #help, #help:hover { opacity: 0.5; cursor: pointer; }
#tooltip { border: 1px solid black; display: none; padding: 0.75em; width: 50%; text-align: center; font-family: sans-serif; font-size:0.8em; }

CodePen :hover on div show text in another div
If you follow this method, element will appear even if you hover over the hidden element. This will be useful if you want to click on the hidden element. For an example you might want to see a delete option and then click on it.
<style>
#delete_link {
display: none;
}
a:hover + #delete_link {
display: block;
}
#delete_link:hover{
display: block;
}
</style>
</head>
<body>
<a>Hover over me!</a>
<div id="delete_link">Element show on hover</div>
</body>
From my testing using this CSS:
.expandable{
display: none;
}
.expand:hover+.expandable{
display:inline !important;
}
.expandable:hover{
display:inline !important;
}
And this HTML:
<div class="expand">expand</div>
<div class="expand">expand</div>
<div class="expandable">expandable</div>
, it resulted that it does expand using the second , but does not expand using the first one. So if there is a div between the hover target and the hidden div, then it will not work.
Don't forget. if you are trying to hover around an image, you have to put it around a container.
css:
.brand:hover + .brand-sales {
display: block;
}
.brand-sales {
display: none;
}
If you hover on this:
<span className="brand">
<img src="https://murmure.me/wp-content/uploads/2017/10/nike-square-1900x1900.jpg"
alt"some image class="product-card-place-logo"/>
</span>
This will show:
<div class="product-card-sales-container brand-sales">
<div class="product-card-">Message from the business goes here. They can talk alot or not</div>
</div>

Is there any way to stop animation repeat/reset after hiding and showing parent element via css only?
Sorry I didn't quite understand the question earlier.
Basically, jQuery's hide/show toggles the target element's display value between none and it's original value. See here.
This means the element is removed from the render tree and losts all its animation states. When you toggle it back, animations you define will be applied to it from the very begining.
To prevent this, you probably need to toggle the CSS visibility value instead of using jQuery's hide/show.
To achieve what you were trying to do, check this fiddle.
My question is one that I was sure would be a common one, but to the best of my efforts, I cannot find any tutorials about this at all.
I am looking to build a text & image navigation menu for a website. It seems to me that many people would want to do something like this, but either I am totally missing a simple concept or many people aren't looking to do something like this.
My Exact Goal: Create a navigation menu with pictures on top and CSS styled text on the bottom. When you focus or hover over the picture, the image changes AND the text changes as if they were one item.
My Problem: On my button, if you hover over the text, the image and text change. If you hover over the image, ONLY THE IMAGE changes as if they are two separate entities.
My HTML:
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<meta charset="UTF-8" />
<link rel="stylesheet" type="text/css" href="test2.css" />
</head>
<body>
<ul>
<li id="onlineRugStore"><b>Button</b></li>
</ul>
The CSS:
body{
background-color:#e8f1c4;
}
#onlineRugStore a{
display:block;
width:191px;
height:107px;
background:url('bestimages/test/worktest.gif') 0 0;
}
#onlineRugStore a:hover{
background:url('bestimages/test/worktest.gif') 0 -107px;
}
#test b{
position:absolute;
text-align:center;
margin:110px 0 0 0;
font-size:18px;
color:white;
text-decoration:none;
border-bottom-left-radius:15px;
border-bottom-right-radius:15px;
width:191px;
height:24px;
background-color:#cc7bd6;
opacity:0.45;
filter:alpha(opacity=45);
padding:4px 0 0 0;
}
#test b:hover{
opacity:1.0;
}
ul{
list-style-type:none;
}
An example of what I am talking about can be viewed at: http://kokorugs.com/test2.php
After exhausting all efforts, I thought that this may be impossible, and then I found a working example on the following website: http://www.amazeelabs.com/en (notice the navigation menu).
I appreciate any and all help.
Happy Holidays,

I've created a JSfiddle for you: http://jsfiddle.net/drXng/
The code you see in the CSS should explain clearly what is going on.
/*CSS you want to apply to the element wrapping both the text and picture*/
.both {
opacity: 0.5;
width: 200px;
height: 200px;
display: block;
}
/*CSS you want to apply to the text only before it is hovered*/
.text {
background-color: green;
}
/*CSS you want to apply to the picture only before it is hovered*/
.picture {
width: 50px;
height: 50px;
}
/*CSS you want to apply to the element wrapping both both the text and picture after hovered*/
.both:hover {
opacity: 1;
}
/*CSS you want to apply to text when both are hovered*/
.both:hover .text {
background-color: blue;
}
/*CSS you want to apply to picture when both are hovered*/
.both:hover .picture {
background-color: red;
}
In your case, it could be easily done by changing .both to ul. For example, the following css will change #test b's opacity as long as anything inside ul is hovered.
ul:hover #test b{
opacity:1.0;
}
P.S. as a word of advice, try to avoid using ID selectors in CSS if you can. :)
I'm using this html code for my buttons :
<a id="my-button" class="btn" name="my-button" href="#">
<span>Some text</span>
</a>
My button is actually composed of two images defined in CSS (i'm using sprites CSS):
.btn {
background-image: url(images/btn-left.png);
}
.btn:hover {
background-position:0 -27px;
}
.btn span {
background-image: url(images/btn-right.png);
}
.btn span:hover {
background-position:0 -27px;
}
I can put text of any size in the span. When I'm over the span, the left and the right button are modified, but when i'm just hover the a tag (a few pixels image) there is just the left button is changed, not the right...
How to change the span style when I'm hover the a tag please ?
I'm not sure why you need to have the span? Why not use one sprite image so you only need to load one image and have something like:
<a class="btn" name="my-button" href="#">
Some text
</a>
and use CSS to process the hover state.
.btn {
width: xxx;
height: xxx;
background-image: url(images/btn-left.png);
background-position:top; /* use one long image with both states for active and hover */
display:block;
}
.btn:hover {
background-position:bottom; /* moves the image down on hover to the lower part of the image */
}
I've made a little example, obviously just using color instead of image. Check it out: http://jsfiddle.net/kkj8n/
Just switch background color to image and use background-position to operate the change in position.
write like this:
.btn:hover {
background-position:0 -27px;
}
.btn:hover span{
background-position:0 -27px;
}
OR
If background position is same then write like this:
.btn:hover, .btn:hover span {
background-position:0 -27px;
}
<style>
#count2{
visibility:hidden;
}
#count1:hover{
background:#123456;
//how do I change the visibility property of #count2 here?
}
</style>
<div id="count1">My visible element</div>
<div id="count2">My flickering element</div>
My question is clear and might be little weird though. How do I change the visibility property of #count2 to true when somebody hovers on #count1, using only css.
Since you're modifying two different elements on hovering one of them, you can use a sibling combinator followed by the #count2 selector in a separate rule for modifying that particular element:
#count2 {
visibility: hidden;
}
#count1:hover {
background: #123456;
}
#count1:hover + #count2 {
visibility: visible;
}
You'll have to use the + selector, which selects adjacent siblings:
#count2 {
visibility:hidden;
}
#count1:hover {
background:#123456;
}
#count1:hover + #count2 {
visibility: visible;
}
Here's the fiddle: http://jsfiddle.net/Yyr64/
If you have to target older browsers, and you're using jQuery, this is what you gotta do:
var $count2 = $('#count2');
$('#count1').hover(function(){
$count2.css('visibility', 'visible');
}, function(){
$count2.css('visibility', 'hidden');
});
...and here's the fiddle for this: http://jsfiddle.net/Yyr64/1/
The above solutions can be abstracted with the following jsfiddle: http://jsfiddle.net/mousepotatoweb/PVHzK/2/
<style>
[id|="count-1"]{
background:#123456;
}
[id|="count-2"]{
visibility:hidden;
}
[id|="count"]:hover ~ [id|="count"] { visibility: visible;}
</style>
<div id="count-1">My visible element</div>
<div id="count-2">My flickering element</div>
count2 would need to be a child of count1 in order to do this via css only.
<div id="count1">
My visible element
<div id="count2">My flickering element</div>
</div>
#count1:hover #count2{ display: block; background: #ffff00; }
#count2{ display: none; }
When using css2 though, you can use the + selector as in Joseph Silber's answer
Use
display:none;
instead of visibility property.
You can take a look at jquery
http://api.jquery.com/show/
I added a "spoiler" class in CSS to use for, well, spoilers. Text is normally invisible but appears when the mouse hovers over it to reveal the spoiler to whoever wants to read it.
.spoiler{
visibility:hidden;
}
.spoiler:hover {
visibility:visible;
}
Should be simple, but for some reason this doesn't work. The text remains invisible even when I point the mouse on it. Any idea what could be causing this?
You cannot hover over a hidden element. One solution is to nest the element inside another container:
CSS:
.spoiler span {
visibility: hidden;
}
.spoiler:hover span {
visibility: visible;
}
HTML:
Spoiler: <span class="spoiler"><span>E.T. phones home.</span></span>
Demo:
http://jsfiddle.net/DBXuv/
Update
On Chrome, the following can be added:
.spoiler {
outline: 1px solid transparent;
}
Updated demo: http://jsfiddle.net/DBXuv/148/
It works not only for text
.spoiler {
opacity:0;
}
.spoiler:hover {
opacity:1;
-webkit-transition: opacity .25s ease-in-out .0s;
transition: opacity .25s ease-in-out .0s;
}
When the text is invisible, it practically does not occupy space, so it's practically imposible to trigger an hover event.
You should try another approach, for example, changing the font color:
.spoiler{
color:white;
}
.spoiler:hover {
color:black;
}
:hover pseudo class is only for a tags according to the CSS spec. User agents are not required to support :hover for non-anchor tags according to the spec.
If you want to use CSS to make visible your spoiler text you will need to place <a> tags around your spoiler content. This of course will mean that the mouse would turn into a pointer, but you can suppress this by adding cursor: none;.
If it's not working the try
.spoiler span {
visibility: hidden;
line-height:20px;
}
.spoiler:hover span {
visibility: visible;
line-height:20px;
}
Try
.spoiler{
display:none;
}
.spoiler:hover {
display:block;
}
