I've got a ux switch that toggles a pictures effect on and off.
http://plnkr.co/edit/JcPXpP0jE5GysBbZbrkp
I want the picture to fade from one to the other over 1 second, but I can't seem to get the fade working in CSS. Any help would be great, thanks.
.off
{
opacity: 1;
-moz-transition: opacity 1s ease-in;
-o-transition: opacity 1s ease-in;
-webkit-transition: opacity 1s ease-in;
transition: opacity 1s ease-in;
position:relative;
z-index:2;
}
From what I can see there is no animation because you are swapping img src attribute. This swap is impossible to animate. What I suggest is that you load both images, place one behind the other and animate opacity of the one in front. Here is my plnkr: http://plnkr.co/edit/7uakbxwZETNnBiOAOfys?p=preview
Try to use the jQuery fade instead: make a .js file, link it to your .html file and try this:
$(document).ready(
$('#yourSwitch').click(
$('#yourImage').fadeOut();
);
);
And the opposite when you try to make it fade in:
$(document).ready(
$('#yourSwitch').click(
$('#yourImage').fadeOut();
);
);

I have a Wordpress website which uses the Dune theme from Zigzagpress.
You can check the site here.
What I want to do is, when hovering over an image, remove the grey layer that the post_image_overlay div has.
I've tried doing it by adding this custom css to the file provided in the theme to do so, custom.css, which gets loaded along with the theme's css:
.post_image_overlay {
opacity: 1;
transition: opacity 1s ease-in-out;
-moz-transition: opacity 1s ease-in-out;
-webkit-transition: opacity 1s ease-in-out;
}
.post_image_overlay:hover {
opacity: 0;
transition: opacity .55s ease-in-out;
-moz-transition: opacity .55s ease-in-out;
-webkit-transition: opacity .55s ease-in-out;
}
But this doesn't seem to make any difference. In fact, with the Chrome inspector and the custom.css file properly loaded, I can see my custom css rules in the .post_image_overlay (for example, if I change the opacity to 0.5, the background is not as dark), but I can't see the .post_image_overlay:hover anywhere. I've even tried to add it directly in the Chrome inspector, but it gets greyed out:
I'd post a JSFiddle but I believe the problem lies beneath some other CSS in the page which is conflicting with my custom one, so I guess it's better to check it live.
BONUS POINTS: Ideally, I'd love to have the background fading out only when the user hovered over the entry title (h2.entry-title), not all the image, but I don't really know if that can be done.
The reason it's not working is because your .entry-content-title has a z-index: 1002; style, which means it's sitting over the top of your .post_image_overlay and therefore you're not hovering over it.
At the moment, I have a style like this:
.clip td{
-webkit-transition: background-color 1000ms linear;
-moz-transition: background-color 1000ms linear;
-o-transition: background-color 1000ms linear;
-ms-transition: background-color 1000ms linear;
transition: background-color 1000ms linear;
}
I then add a css class and then use setTimeout to remove the class giving a simple fade animation.
Is it possible to achieve the same effect without javascript and have a complete css solution?
Use CSS3 animation and use it's delay and timing functions. You probably still end up using JS to trigger the animation if it doesn't happens right after page load.
Chris has a nice article to help you understand and write CSS3 animations:

Ok so I am trying to create an inversion effect on hover of the silhouette, I've gotten all the CSS to change accordingly and used some minor JS to replace the image but the fading transition for the image goes much quicker than everything else. Even when setting the time to far more than it should be it does not seem to effecting it.
You should be able to see my style sheet at the link below, it's pretty tiny but I figured I'd let you guys see it all instead of the specific lines I'm talking about because I believe there could be a conflict.
http://coreytegeler.com/new/css/style.css
#shadow {
width:33%;
-webkit-transition: all 2.2s ease-in-out;
-moz-transition: all 2.2s ease-in-out;
-o-transition: all 2.2s ease-in-out;
transition: all 2.2s ease-in-out;
}
#shadow:hover {
-webkit-transition: all 2.2s ease-in-out;
-moz-transition: all 2.2s ease-in-out;
-o-transition: all 2.2s ease-in-out;
transition: all 2.2s ease-in-out;
}
Your code is not working on :hover because you simply change source of img. CSS has nothing to do with it.
You can place image in a div and set other image as div's background-image. Then on hover just reduce opacity to 0.
Demo
EDIT
In future you can use CSS filter property. Currently its supported by just -webkit. It'll be as simple as
img {
filter: invert(100%);
}
and you're done. But currently its just
img {
-webkit-filter: invert(100%);`
/*-moz -o -ms all are unimplimented*/
}
Proof of concept (Use chrome or safari to see the effect)
+filter(W3C)
I was wondering if it was possible to state an unhover class at all on an image?
What I am trying to achieve is when someone hovers over an image it will fade in and then when they unhover it fades back out?
Heres my code, I got the fade in to work when someone hovers over an image but I need it too fade out when they unhover... hope this made sense.

This should work for you! http://jsfiddle.net/L7XCD/1/
Let's use the great mozilla documentation to explain this:
Transition rovide a way to control the speed of animation changes to CSS properties. Instead of having the animation changes take effect instantly, you can transition the property changes over a specified time period.
Also we used the transition timing functions (ease, linear, easy-in, easy-out, easy-in-out)
Timing functions determine how intermediate values of the transition are calculated. The timing function can be specified by providing the graph of the corresponding function, as defined by four points defining a cubic bezier
CCS markup:
img {
opacity: 0.6;
transition: opacity 1s ease-in-out;
-moz-transition: opacity 1s ease-in-out;
-webkit-transition: opacity 1s ease-in-out;
}
img:hover {
opacity: 1.0;
transition: opacity .55s ease-in-out;
-moz-transition: opacity .55s ease-in-out;
-webkit-transition: opacity .55s ease-in-out;
}
Since he was using the transition ease-in-out, I thought it was better to use the same transition function.
For more information, check the documentation here
Hope it helps!

Just add the transition effect to your element without the hover-tag
Simple enough question:
Is it possible to leverage css transitions when it would would not be appropriate/feasible to trigger animations via pseudo selectors (ie :hover, :active, etc)?
My use case is I want something to animate after form submission. I was thinking I would be able to do something like:
.success_message { ...transition stuff + opacity: 0 }
.success_message.shown { opacity: 1 }
Then using javascript, I would add the shown class to this element I want to animate.
Why not just use jQuery or similar to animate? I'm glad you asked. The CSS Transitions are much smoother on the iPhone and other mobile devices, which are the platforms I'm targeting. Currently I'm doing animations with jQuery, but they're just not as smooth as they could be.
Edited to clarify what I was asking about pseudo-selectors.
Everything should work as you expect. JSFiddle: http://jsfiddle.net/ghayes/zV9sc/12/
.success_message {
opacity: 0.0;
transition: opacity 0.3s linear;
-webkit-transition: opacity 0.3s linear;
-moz-transition: opacity 0.3s linear;
-o-transition: opacity 0.3s linear;
}
.success_message.shown {
opacity: 1.0;
}
If this does not solve your issue, please include further code samples or browser specifics. Good luck!
Yes, you can do that. Css transitions work any time a css property changes, even if it was because the class changed.
