Smooth Transition On Hovering

I've been working on finding a way to change out this <img id="repair" src="http://d3vi9nkvdbmq5l.cloudfront.net/service-icons/Repair.svg" by using a :hover with an image called repair_h.svg. What I initially was doing was placing a :hover on #repair like so #repair :hover and giving repair a background-image:url but this was not working and I think there are a few reasons why.
That was my initial process...Since that did not work I did some research on how to achieve this correctly and found a way to achieve it with JS. Which is way less hackie than some other css and html solutions I was looking into.
Using JS ended up working great for the purpose of what I need done although there's one piece that I'd like to add to this and I'm not quite sure how to do it.
I'd like to add a smooth transition between the image's when hovered on.

HTML
<li>
<a href="#">
<img id="repair" src="http://d3vi9nkvdbmq5l.cloudfront.net/service-icons/Repair.svg"
onmouseover="this.src='http://d3vi9nkvdbmq5l.cloudfront.net/service-icons/hov/Repair_h.svg'"
onmouseout="this.src='http://d3vi9nkvdbmq5l.cloudfront.net/service-icons/Repair.svg'" border="0" alt="About Plumbing Repairs in Honolulu Hawaii">
</img>
</a>
</li>
JS
function hover(element) {
element.setAttribute('src', 'http://d3vi9nkvdbmq5l.cloudfront.net/service-icons/hov/Repair_h.svg');
}
function unhover(element) {
element.setAttribute('src', 'http://d3vi9nkvdbmq5l.cloudfront.net/service-icons/Repair.svg');
Also if any of you have any suggestions on away to perform a this entire task without JS and entirely with HTML and CSS then I'd be open to seeing how you'd do it :)
Thanks

You can do something like this with markup and css only:
HTML:
<a href="#">
<img id="repair" src="http://d3vi9nkvdbmq5l.cloudfront.net/service-icons/Repair.svg" border="0"
alt="About Plumbing Repairs in Honolulu Hawaii" />
</a>
CSS:
a {
background:url('http://d3vi9nkvdbmq5l.cloudfront.net/service-icons/hov/Repair_h.svg') 0 0 no-repeat;
width:150px;
margin:0;
padding:0;
float:left;
}
a img {
opacity:1;
transition:opacity .5s;
float:left;
}
a:hover img {
opacity:0;
transition:opacity .5s;
}
Demo

In CSS you cannot transition/animate directly between two images becuase CSS is incapable of interpolating keyframes between two none value-scale values.
That said, there are a few approaches using only CSS.
If you need to keep the same element/id the images are being transitioned on, the only approach would be to replace the image with a non-replaced element so you can use pseudo elements, then do e.g.:
span {
display: inline-block;
position: relative;
}
span:before,
span:after {
display: inline-block;
height: 300px;
width: 300px;
overflow: hidden;
position: absolute;
top: 0;
left: 0;
}
span:before {
content: url(http://d3vi9nkvdbmq5l.cloudfront.net/service-icons/Repair.svg);
}
span:after {
opacity: 1;
transition: opacity 200ms ease-in;
content: url(http://d3vi9nkvdbmq5l.cloudfront.net/service-icons/hov/Repair_h.svg);
}
span:hover:after {
opacity: 0;
}
<span></span>
Alternatively if this isnt a consideration, a common approach is to overlap two images and transition the opacity of the correct image on hover, revealing the image underneath.
div:hover img:last-of-type {
opacity: 1;
transition: opacity 200ms ease-in;
}
div:hover img:last-of-type {
opacity: 0;
}
div img {
position: absolute;
top: 0;
left: 0;
}
<div>
<img src="http://d3vi9nkvdbmq5l.cloudfront.net/service-icons/Repair.svg" />
<img src="http://d3vi9nkvdbmq5l.cloudfront.net/service-icons/hov/Repair_h.svg" />
</div>

If you remove the blue background from the image(s) and keep it transparent, you can do this easily with css:
<style type="text/css">
ul {
list-style: none;
}
a {
display: inline-block;
width: 230px;
height: 240px;
background-color: #8bdafc;
/* background-image: url(/path/to/img/with-transparent-bg.svg) */
background-repeat: no-repeat;
-webkit-transition: background-color .3s;
-moz-transition: background-color .3s;
-o-transition: background-color .3s;
transition: background-color .3s;
}
a:hover {
background-color: #4fc3fb;
}
</style>
<ul>
<li>
</li>
</ul>

Don't set an src attribute on the img
<img src='' width=500 height=500>
img{
background: url("src1");
}
img:hover{
background: url("src2");
}

jQuery: Is it possible to use slideUp and append text at the same time?

When a user mouses over a picture, I want to slideUp a description, so that new text will appear. When the user mouses out, the description will slideDown.
This is what I've tried so far:
$pic1.hover(function () {
var text1 = $("<div>Price1:$100</div>").hide();
text1.appendTo($('.this')).slideUp("slow");
},function () {
$(this).slideDown();
}
);
Unfortunately, this doesn't work. I googled around, but couldn't find anything. Is it possible to use slideUp and slideDown to show and hide the text?

A better approach would be to use CSS transitions. They're lightweight and easy to do. You can read the specification on transitions here. Here is a quick guide on the matter.
fiddle
HTML
<div class="imageDiv">
<img src="http://placekitten.com/g/200/300" />
<div class="imageDescription">
What a lovely kitty kat!
</div>
</div>
CSS
.imageDiv {
display: block;
float: left;
overflow: hidden;
position: relative;
width: 200px;
}
.imageDescription {
-webkit-transition: top 0.5s ease;
-moz-transition: top 0.5s ease;
-ms-transition: top 0.5s ease;
-o-transition: top 0.5s ease;
transition: top 0.5s ease;
background: rgba(0, 0, 0, 0.4);
color: #f7f7f7;
left: 0;
position: absolute;
text-align: center;
text-decoration: none;
top: 100%;
width: 100%;
}
.imageDiv:hover .imageDescription {
display: block;
top: 93%;
}
There a few key things that make this work. First, a CSS transition is used. Transitions are written in the following form:
transition: [property] [duration] [timing-function] [delay];
As can be seen in the example above, I used a transition that targeted the top attribute. I gave it a 0.5s duration and an ease effect. However, this alone wouldn't produce the effect, as the description would just sit below the image and move up on hover. We don't want to see the description until the user hovers over the image!
To address this, you need to add overflow: hidden; to the parent div.imageDiv. This hides the image description, until the transition, when it will be slide up, causing it to no longer overflow.

http://jsfiddle.net/qvbgb/3/
HTML
<div class="imgcontainer">
<div class="image">
<img src="link.jpg" />
</div>
<div class="text">
<h3>Product name</h3>
<p>Description</p>
</div>
</div>
Jquery
$(document).ready(function(){
$('.text').hide();
$('.container').hover(
function () {
$(this).find('.image').slideUp();
$(this).find('.text').slideDown();
},function () {
$(this).find('.text').slideUp();
$(this).find('.image').slideDown();
}
);
})
CSS
.container{
min-width : 150px;
min-height : 150px;
width : 150px;
height : 150px;
cursor : pointer;
display : block;
}
.image img{
width : 150px;
height : 150px;
}

slideUp() will only hide an element, and slideDown() will only show an element. If you want to show an element with slideUp effect or hide with slideDown effect, you have to explicitly call it:
$(text1).show("slide", { direction: "up" }, 1000);
$(text1).hide("slide", { direction: "down" }, 1000);

ease toggle with jquery/html/css3 not working in ie properly

JSfiddle
Here is a fiddle for what I am trying to do. I am trying to use pure css with exception of jquery to toggle the appropriate class and let the css transitions handle the rest. I know this isn't supported by old IE's which is fine with me at this point.
What is happening is for when ever I click the link text the on/off the slider moves and eases just fine. However, when I hit the actual slider portion of the button it moves over suddenly with no easing. Here is the code:
HTML
<a href="#" class="on-off">
<span class="on">ON</span>
<span class="off">OFF</span>
<span class="slider right ease"></span>
</a>
CSS
.on-off {
display: inline-block;
position: relative;
padding: 5px;
background: #ff8600;
border-radius: 5px;
border: 1px solid #b8baba;
}
.on-off .on {
margin-right: 10px;
}
.slider {
position: absolute;
width: 50%;
height: 100%;
background: #fff;
z-index: 2;
border-radius: 5px;
border: 1px solid #b8baba;
}
.right {
top: 0;
right: 0;
}
.left {
top: 0;
right: 50%;
}
.ease {
-webkit-transition: all .5s ease;
-moz-transition: all .5s ease;
-ms-transition: all .5s ease;
-o-transition: all .5s ease;
transition: all .5s ease;
}
Javascript
$('.on-off').on('click', function() {
$slider = $('.slider');
if ($slider.hasClass('right')) {
$('.slider').removeClass('right');
$('.slider').addClass('left');
} else {
$('.slider').removeClass('left');
$('.slider').addClass('right');
}
})
This does work in chrome/firefox just fine. Just not IE10/11. I am trying to use graceful degradation. Keep things lightweight so if css can handle it not to use javascript where also it has basic functionality it just might toggle rather than ease in unsupported browsers. I know IE10/11 supports ease as it is working. just not when I click that particular area of the button.
Thanks for the help.

Hey this is going to sound dumb, but here's the solution
$('.on-off').on('click', function() {
$slider = $('.slider');
if ($slider.hasClass('right')) {
$('.slider').addClass('left');
$('.slider').removeClass('right');
} else {
$('.slider').addClass('right');
$('.slider').removeClass('left');
}
});
Add before you remove, and add a semicolon to your function.

Start a CSS transition via JS does not work

I want to start a CSS transition, that changes the background-color and the dimension if a button is clicked. But there is a mistake in the code:
js fiddle
jQuery
$(function() {
$('#change').click(function() {
$('#box').addClass('change');
});
});
HTML
<div id="box" class="start"></div>
<div id="button">click</div>
CSS
.start{
height:100px;
width:100px;
background: black;
transition: all 2.0s linear;
-webkit-transition: all 0.8s linear;
-moz-transition: all 0.8s linear;
-ms-transition: all 0.8s linear;
-o-transition: all 0.8s linear;
}
.change{
width: 200px;
height: 200px;
background:yellow;
}
#button{
width: 80px;
height: 20px;
padding: 4px;
margin: 5px;
border:solid 1px black;
background: grey;
cursor: pointer;
color: white;
}

The id of the button in the HTML & CSS (#button) is different from the id of the button in the JS (#change), that's why.
If you replace #change with #button in the JS, then it works.
Note: When you list transition rules for various browsers, you don't need the -ms- one (IE10 supports transitions unprefixed and IE9 does not support them at all; the -ms- prefix was only needed for early IE10 previews) and you should always put the unprefixed one last. At this point, all current versions of desktop browsers support transitions unprefixed.

Id of your button is button, not change.
Use $('#button') instead of $('#change').
DEMO HERE.

It should be using #button,
$(function() {
$('#button').click(function() {
$('#box').addClass('change');
});
});
as per your HTML
<div id="button">click</div>

How to change the text of a table cell while hovering using only CSS3

I was wondering if anyone in SO would be kind enough to assist me. Using only CSS (most-likely CSS3), is there a way to change the inner HTML of a table cell while hovering over the element? I have a numerical table with 49 cells (7 rows by 7 columns), and I would like the number in the first cell of the first row to change from number 1 to number 50, but only when hovering over the number 1 (i.e. - changing back to number 1 when not hovering).
I can do this with a "change innerHTML" function in JavaScript, but only when using a portion of the script inline with my HTML within the body of the document. For various reasons, I cannot use any script or CSS inline, so this method of achieving my goal is not what I want to use (this goes beyond semantic reasons). I would really rather avoid using any script at all for this effect because I think CSS3 handles effects more elegantly and selectively than JavaScript (i.e. - CSS3 Tooltips are much nicer than any script-based Tooltip).
I was just wondering if someone knew how to do this using CSS3 (maybe with the z-index, display: none; or positioning techniques somehow?}. I've played around with it, but I can't seem to figure it out. I would use JavaScript if I didn't have to mix the script in with my Markup, but there doesn't appear to be a way to do that.
Anyone have ideas on how to go about this? Thank you for your time.
Update
#ramsesoriginal
#hiphip
Thanks again. I answered "Yes" to the "Did this answer help you." I believe that is what you meant by "as accepted" ramsesoriginal; right? Thanks hiphip for your answer as well. I was playing around with styles like the code below, but it wasn't quite working out in the table cell the way I had hoped (works nice with isolated images by the way). I think I'll keep working on it though; the more options, the better.
div.up {
margin: 10px 0;
position: relative;
width: 40px;
height: 40px;
border: 1px solid rgb(170, 169, 169);
overflow: hidden;
}
div.up div {
width: 40px;
height: 40px;
font-size: 13px;
padding: 10px;
position: absolute;
top: 0;
left: 0;
text-align: center;
background: rgba(255, 255, 255, 1.000);
-moz-transition: left 1s linear;
-webkit-transition: left 1s linear;
-o-transition: left 1s linear;
transition: left 1s linear;
}
div.up div.one {
z-index: 999;
}
div.up:hover div.one {
-webkit-transition: left 1s linear;
-moz-transition: left 1s linear;
-o-transition: left 1s linear;
transition: left 1s linear;
left: -99px;
}

There are two ways, but both require some additional markup:
<td id="example1" class="hoverer"><span class="nohower">1</span><span class="hover">50</span></td>
with the styling
#example1 .hover{
display:none;
}
#example1 .nohower{
display:block;
}
#example1:hover .hover{
display:block;
}
#example1:hover .nohower{
display:none;
}
or
<td id="example2" class="hoverer"><span data-hover="50">1</span></td>
with the styling
#example2:hover span:after{
content:attr(data-hover);
}
#example2:hover span{
width:1px;
margin-left: -0.5em;/* adjust accoridng to font*/
}
You can view a working demo here: http://jsfiddle.net/ramsesoriginal/W8LQq/

This is not possible.
CSS is only used for styling HTML. It has no access to the attributes of the HTML itself.

No way to do this with only CSS

With positioning:
<style>
#outterdiv {
position: relative;
width:20px;
height:20px;
overflow:hidden;
border: 1px blue solid;
}
#innerdiv:hover {
width:20px;
height:20px;
position: absolute;
top: -20px;
}
</style>
<div id="outterdiv">
<div id="innerdiv">
<div>1</div>
<div>50</div>
</div>
</div>
