I'm looking for some help with this project. I want to be able to hover over the image and this black box pops up with the description in it. Can I get some examples of how I would go about doing this? Thank you all so much for the help!
what I'm looking to do when user hovers over the image for a description
with pure css you can do something like this
#image_description {
display: none;
background-color : #333;
color : #fff;
padding : 50px;
}
#the_image:hover~#image_description{
display: block;
}
<img src="https://placehold.it/350x150" id="the_image">
<div id="image_description">SomeDescription</div>
with jQuery you can do something like this
$(document).ready(function(){
$("#the_image").hover(function(){
$("#image_description").fadeIn();
}, function(){
$("#image_description").fadeOut();
});
});
#image_description { display : none }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<img src="https://placehold.it/350x150" id="the_image">
<div id="image_description">SomeDescription</div>
#Allan Empalmado is correct. But you can add CSS transitions to make it flow in and out smoothly, with pure CSS transition property. Add this to the code...
#image_description {
background-color: #333;
color: #fff;
oveflow:hidden;
-webkit-transition: max-height 0.9s ease;
-moz-transition: max-height 0.9s ease;
transition: max-height 0.9s ease;
max-height:0;
}
#the_image:hover ~ #image_description{
max-height: 150px;
}
The -webkit- and -moz- make the CSS cross-browser. it is a simple google search to find other properties you can manipulate with the transition properties.Hopefully you can find other things you can do to enhance Alans sample code. happy coding !!

My CSS:
a:hover {
position: relative;
}
a:hover:after {
z-index: -1;
content: url(icon.jpg);
display: block;
position: absolute;
left: 0px;
bottom: 20px;
}
This displays an icon when I hover over an anchor, from this post:
Make image appear on link hover css
I am trying to apply this:
-webkit-transition: all 0.3s ease-in;
-moz-transition: all 0.3s ease-in;
-o-transition: all 0.3s ease-in;
So that the image fades in, but I cant get it to work.
WebKit (Chrome, Safari) does not support transitions on pseudo elements. It should work in Firefox.
see this q/a
To accomplish your need you could apply the background image for the link and in hover you could apply the transition by setting the background-position. You can also use an extra span inside the a tag instead of using :before pseudo class.
You could do a background image.
a {
-webkit-transition: all 0.3s ease-in;
-moz-transition: all 0.3s ease-in;
-o-transition: all 0.3s ease-in;
}
a:hover {
position: relative;
background:url(icon.jpg);
}
The code is just an example, you would need to position the background image as well, since I dont know the dimensions of your design I can't tell you the exact position.
Webkit currently support transitions and animations
http://css-tricks.com/transitions-and-animations-on-css-generated-content/
a:hover {
position: relative;
}
a:after{
-webkit-transition: all 0.3s ease-in;
-moz-transition: all 0.3s ease-in;
-o-transition: all 0.3s ease-in;
transition: all 0.3s ease-in; /*never forget the standard*/
}
a:hover:after {
z-index: -1;
content: url(icon.jpg);
display: block;
position: absolute;
left: 0px;
bottom: 20px;
}

There are some css "tricks" that can help you, maybe using css keyframes, but the best way to perform this in a compatibility way is using jQuery (a jquery version that matches your compat needs).
As some people asked you on css, where webkit actually support this kind of transitions, and this question could grow if we start talking on standards, the best you can do at first is update all your browsers and check.
If you need or want to keep compat on older browser versions, you'll need to catch the hover event with javascript and then do whatever you want (as javascript can work directly with the DOM) and with CSS is pre-loaded and the most you can do is change the properties. i.e.
load image with display: none, then change this property with an event.
example on jquery:
$('.link').click(function(){
$('.foo').fadeIn();
});
$('.link2').click(function(){
$('.foo2').fadeToggle();
if($('.link2').text() == 'show or hide') $('.link2').text('click again');
else $('.link2').text('show or hide');
});
.foo, .foo2{display: none; width: 100px; height: auto;}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p>
<img class="foo" src="http://joelbonetr.com/images/root.jpg" alt="">
<a class="link" href="#">show it!</a>
</p>
<p>
<img class="foo2" src="http://joelbonetr.com/images/root.jpg" alt="">
<a class="link2" href="#">show or hide</a>
</p>
I'm trying to animate a page element using CSS transition on opacity property. Fading out works properly, but Fading in doesn't. What am I doing wrong?
Some facts are really strange:
Without using .no-display class everything works as expected (but I should use it).
Replaying function's commands in browser console does work as expected (but function does not).
The code:
HTML
<p>Fade in</p>
<p>Fade out</p>
<div class="no-display invisible" id="square"></div>
CSS
.no-display {
display: none;
}
.invisible {
opacity: 0;
}
#square {
width: 500px;
height: 500px;
background-color: red;
border: 1px solid black;
-webkit-transition: opacity 2s ease;
-moz-transition: opacity 2s ease;
-ms-transition: opacity 2s ease;
-o-transition: opacity 2s ease;
transition: opacity 2s ease;
}
JavaScript
function fadeIn() {
square.classList.remove("no-display");
square.classList.remove("invisible");
}
function fadeOut() {
square.classList.add("invisible");
setTimeout(function() { square.classList.add("no-display"); }, 2000 );
}
Or: http://jsfiddle.net/V2Sar/6/.
Note, I can't use any frameworks such as jQuery. I have to work only with pure JavaScript.
The easy way to trigger CSS transitions with JS is to toggle classnames, and the easy way to do that is through the classList API.
js
var square = document.getElementById("square");
function fadeIn() {
square.classList.remove("invisible");
}
function fadeOut() {
square.classList.add("invisible");
}
css
#square {
opacity: 1;
transition: opacity 2s ease;
}
#square.invisible {
opacity: 0;
}

Also, make sure your scripts are at the end of the <body> so you don't need to worry about whether the DOM is constructed yet (separate option in jsfiddle for this).
The browser support isn't great (no support in IE9) but there is a shim available at https://github.com/eligrey/classList.js
Let me know if this isn't good enough for you and I'll post some alternatives as well.
The only problem is "display: none;". Simply replace it with 'visibility: hidden'.
The reason is that 'display: none' doesn't build the resulting element in the DOM. As such, it cannot fade in something that does not exist. When its created, its created in a visible way.
'visibility: hidden', however, does build the resulting element in the DOM, simply doesn't show it. Because it exists, it can fade in when required.
Hi I'm trying to animate a background image using jQuery, I tried following this tutorial here, however I've had no luck with my test page, I see the blue Facebook icon, but on mouse over it does not animate upwards to reveal the gray logo. Please help! Thanks, I'm a jQuery noob.
My test page:
http://leongaban.com/_stack/bg_animation/
The Facebook icon should animation upwards, the full image below:
My CSS
<style>
#facebook_icon li {
padding: 0;
width: 120px;
height: 119px;
list-style: none;
background: red;
background:url('img/fb_120x238.png') repeat 0 0;
}
</style>
HTML
<ul id="facebook_icon">
<li><div class="box"></div></li>
</ul>
Javascript
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
<script type="text/javascript" src="js/jquery.bgpos.js"></script>
<script>
(function() {
$('#facebook_icon li')
.css( {backgroundPosition: "0 0"} )
.mouseover(function(){
$(this).stop().animate(
{backgroundPosition:"(0 -119px)"},
{duration:500})
})
.mouseout(function(){
$(this).stop().animate(
{backgroundPosition:"(0 0)"},
{duration:500})
})
})();
</script>
UPDATE: WORKING CSS 3 Solution
CSS 3
#facebook_icon li {
padding: 0;
width: 120px;
height: 119px;
list-style: none;
background: red;
background:url('img/fb_120x238.png') repeat 0 0;
-moz-transition: background-position 1s;
-webkit-transition: background-position 1s;
-o-transition: background-position 1s;
transition: background-position 1s;
background-position: 0 0;
}
#facebook_icon li:hover{
background-position: 0 -119px;
}
.box {
width: 120px;
height: 119px;
}
HTML (Added empty div box to have something to click on)
<ul id="facebook_icon">
<li><div class="box"></div></li>
</ul>
A simple solution should be using the css3 transition.
You can do something like this:
In Your CSS
#facebook_icon li{
-moz-transition: background-position 1s;
-webkit-transition: background-position 1s;
-o-transition: background-position 1s;
transition: background-position 1s;
background-position: 0 0;
}
#facebook_icon li:hover{
background-position: 0 -119px;
}
This one is thankfully pretty simple. You are animating background-position on the anchor, but the actual image is on the li.
Just change your selector in your JavaScript:
$('#facebook_icon li')
However, I'd recommend changing your markup (and accompanying CSS) so the a is inside the li instead of a child of the ul. That way your markup is valid.
Update:
Hey, so I totally agree with using CSS3. Its exactly how I would implement that. But just to close out the question: To get the bgpos plugin working with jQuery 1.8.2, change the first two lines of the backgroundPosition method to this:
if (fx.start === 0 && typeof fx.end == 'string') {
var start = $.css(fx.elem,'backgroundPosition');
I'm coding a website and I'm trying to replicate the effect on the apple.com where when you click to focus the search field in the menu bar, and the search field expands and the rest of the menu bar shrinks to accommodate it.
I've been trying various tricks with jquery kwicks, and also simply expanding a text field using the animate function in jquery but the effect is not the same. If someone could get me on the right track I'd very much appreciate it!
Best
Daniel
this can be done by css only no need for javascript or anything...
#search input {
width: 100px;
-moz-transition: width 0.5s ease-out;
-webkit-transition: width 0.5s ease-out;
transition: width 0.5s ease-out;
}
#search input:focus {
width: 200px;
-moz-transition: width 0.5s ease-out;
-webkit-transition: width 0.5s ease-out;
transition: width 0.5s ease-out;
}
voila, thats it ;)
Taking a quick look at how Apple did it, it looks like their big move is this (I could be wrong - I'm rushing):
#globalheader #globalnav li {
display: table-cell;
width: 100%;
overflow: hidden;
}
This is a pretty unusual CSS display value, and clever on their part, forcing the <li>'s to work like <td>'s. This means that changing the width of one of the "cells" causes the others in the same "row" to adjust how much room they take out.
Long live (fake) table-based layout!
So, assuming that CSS is possible for you, and I'm not off base with my quick glance at their code, your only task is to animate the width of the search box - the rest should follow suit.
Not to over simplify things but what if in your css you float:right; this input box and then on focus you animate the box to the appropriate width like so:
CSS:
#inputtext{
float:right;
width:150px;
}
jQuery:
$("div#inputtext").focus(function(){
$(this).animate({width:'300px'}, 1000);
});
This is a fiddle for this.
http://jsfiddle.net/MenuSo/r4xq9gz2/
HTML:
<form id="expanding-form">
<input type="text" id="expanding-input" placeholder="">
<button type="submit">Search</button>
</form>
and CSS:
#expanding-form input{
width: 30px;
height: 30px;
-o-transition: width .5s ease;
-ms-transition: width .5s ease;
-moz-transition: width 0.5s ease-out;
-webkit-transition: width 0.5s ease-out;
transition: width 0.5s ease-out;
}
#expanding-form input:focus{
width: 200px;
}
CSS would be enough.
My problem..
I have a number of images (inside hyperlinks), and I want each to darken on mouseover (i.e. apply a black mask with high opacity or something), and then go back to normal on mouseout . But I can't figure out the best way to do it.
I've tried..
Jquery color animate and some javascript references.
Setting the opacity of the image with javascript.
I don't want..
Image start at 80% opacity then go to 100% on mouseover (that's easy).
To swap between 2 images (one light & one dark), forgot the mention this sorry..
To reiterate..
I want in image (inslide a hyperlink) to darken on mouseover and then lose its darkness on mouseout.
Thoughts?
UPDATE :
This is my progress from suggestions. Looks fine in IE8, but not in FF3

I'm going with this (seems to work in IE8 & FF)
<html>
<head>
<style type="text/css">
.outerLink
{
background-color:black;
display:block;
opacity:1;
filter:alpha(opacity=100);
width:200px;
}
img.darkableImage
{
opacity:1;
filter:alpha(opacity=100);
}
</style>
</head>
<body>
<a href="http://www.google.com" class="outerLink">
<img src="http://www.google.co.uk/intl/en_uk/images/logo.gif" width="200"
class="darkableImage" onmouseout="this.style.opacity=1;this.filters.alpha.opacity=100"
onmouseover="this.style.opacity=0.6;this.filters.alpha.opacity=60" />
</a>
</body>
</html>
Or, similar to erikkallen's idea, make the background of the A tag black, and make the image semitransparent on mouseover. That way you won't have to create additional divs.
CSS Only Fiddle (will only work in modern browsers)
JavaScript based Fiddle (will [probably] work in all common browsers)
Source for the CSS-based solution:
a.darken {
display: inline-block;
background: black;
padding: 0;
}
a.darken img {
display: block;
-webkit-transition: all 0.5s linear;
-moz-transition: all 0.5s linear;
-ms-transition: all 0.5s linear;
-o-transition: all 0.5s linear;
transition: all 0.5s linear;
}
a.darken:hover img {
opacity: 0.7;
}
And the image:
<a href="http://google.com" class="darken">
<img src="http://www.prelovac.com/vladimir/wp-content/uploads/2008/03/example.jpg" width="200">
</a>
Make the image 100% bright so it is clear.
And then on Img hover reduce it to whatever brightness you want.
img {
-webkit-transition: all 1s ease;
-moz-transition: all 1s ease;
-o-transition: all 1s ease;
-ms-transition: all 1s ease;
transition: all 1s ease;
}
img:hover {
-webkit-filter: brightness(70%);
filter: brightness(70%);
}
<img src="http://dummyimage.com/300x150/ebebeb/000.jpg">
That will do it,
Hope that helps
I realise this is a little late but you could add the following to your code. This won't work for transparent pngs though, you'd need a cropping mask for that. Which I'm now going to see about.
outerLink {
overflow: hidden;
position: relative;
}
outerLink:hover:after {
background: #000;
content: "";
display: block;
height: 100%;
left: 0;
opacity: 0.5;
position: absolute;
top: 0;
width: 100%;
}
How about this...
<style type="text/css">
div.frame { background-color: #000; }
img.pic:hover {
opacity: .6;
filter:alpha(opacity=60);
}
</style>
<div class="frame">
<img class="pic" src="path/to/image" />
</div>
Put a black, semitransparent, div on top of it.
Create black png with lets say 50% transparency. Overlay this on mouseover.
