Is there any known issue when making a CSS transition to elements inside columns?
I've problems in webkit (Safari and Chrome), didn't test others...
I've made a simple demo where a transition is applied (on hover) to a image that sits inside columns. The problem happens on all columns except the first, it won't render the applied filter or the transition.
The first column works as expected, and if I remove the columns also render ok.
This is a relevant part of the CSS:
#photos img {
width: 100% !important;
height: auto !important;
opacity: 1;
-webkit-filter: blur(0);
-webkit-transition: all 200ms ease-in;
}
#photos div:hover img {
opacity: 0.25;
-webkit-filter: blur(2px);
-webkit-transition: all 200ms ease-in;
}
If you need "absolute" positioned elements in the columns, you will need that "relative" postition.
At Google Code there is a solution under "Issue 177556: Opacity transitions fail in CSS columns"
Don't remove position:relative, just add this:
-webkit-column-break-inside:avoid;
-moz-column-break-inside:avoid;
-o-column-break-inside:avoid;
-ms-column-break-inside:avoid;
column-break-inside:avoid;
-webkit-backface-visibility:hidden;
Chrome Version: Version 35.0.1916.114 m
EDIT : You can also add :
display:inline-block;
(it solved one of my issues, when using :after css selector on child elements.)
Apart from the rendering/flickering problems due to the columns, I figured out that the position:relative; of your divs cause the transition render problem.
If you want to keep up with this layout try to style the div content without position:absolute;.

I am creating a website for a project and got stuck with an issue.
I was trying to implement the hover feature, where when I hover over the image it gets zoomed in. That part works nicely, however, I was having an issue when I hover over the last book in the first row. When I hover over that, the entire screen becomes glitchy. This feature is not working as I hoped, i.e. smooth and good to work with. I have attached the image and the code I have.
Thanks for any help!
.books img{
width:200px;
height:300px;
}
.books img:hover {
position: relative;
left: 45px;
width: 300px;
height: 400px;
display: block;
}
I found some code online using -mox-transform and -webkit-transform, however, I have never worked with that before. This seemed complex for me. Any suggestions if I should learn how that works instead of perfecting the above code?
By increasing the width and height on hover the surrounding layout must adapt to that size change. The browser must move the surrounding elements to provide the space for the larger element, that is why it is glitchy.
If you want to do it properly, you will probably have to use transform, as you mentioned.
For your use case it should not be hard. Try this:
.books img {
width: 200px;
height: 300px;
transition: transform 200ms; /* optional transition with 200ms duration */
}
.books img:hover {
transform: scale(1.1); /* scale to 110% */
}
All you need to use is scale property to scale the image. Change your code to this
.books img:hover {
transform: scale(1.5);
}
This should do what you are looking for.
Use transform CSS Property with scale() which is used to increase or decrease the size of an element
.books img:hover {
transform: scale(1.2);
}
I have a simple div element in my HTML, I have set the background-image property to a still image but used the :hover class to change the background-image property to an animated GIF, this works fine for my purposes but when the user leaves the element (stops hovering) the GIF stops and is immediately replaced by the still image, looking a bit displeasing.
I assume this would require JavaScript or jQuery to handle which I'm fine with but if there is any other easier ways that can be implemented into the CSS itself that would be great.
Thanks
jsfiddle: https://jsfiddle.net/nxt5ktc1/
my example itself: drawdeloop.co.uk
header .headerButtonNav {
background-image: url('../Images/Icons/ringUnglow100100.png');
background-size: cover;
width: 50px;
height: 50px;
position: absolute;
right: 50px;
top: 60px;
}
header .headerButtonNav:hover {
background-image: url('../Images/Resources/circleCrossButton400400.gif');
}
You could add a transition to your .headerButtonNav to make it feel more 'smooth'.
I've updated your Fiddle to see what I did: https://jsfiddle.net/nxt5ktc1/1/
Why don't you use CSS transition property?
For example:
-webkit-transition: background-image 0.2s ease-in-out;
transition: background-image 0.2s ease-in-out;
Try insert images in html code and hidden their (display: none), that would they can loading before
I am trying to do a simple image fade on rollover - works fine and smooth in Chrome, but Firefox is a bit jumpy. I've tried doing the backface-visibility trick on the container, but still no luck.
Anyone have any ideas?
JSFiddle
HTML
<div class="link-box large">
<div class="image">
<img src="https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcRStwH3maKRqLU8lLOo1XbO6uZIKHRyf2PGv66H6ol5mB0kS_0r" alt="">
</div>
</div>
CSS
.link-box .image img { transition: all .2s ease-out; width:200px; }
.link-box.large { position: relative;}
.link-box.large:hover .image img { opacity: .65; }
My best guess is that setting the width of the image to 200px and leaving the height unspecified is causing the browser to calculate the height of the image. If the height calculates to a nice whole number it isn't an issue. If the height calculates to a decimal it may be the cause of the problem.
In this case the natural dimensions of the image are 275px by 183px.
By changing the width of the image to 200px you are shrinking the image to 72.727272...% of its natural size.
275/200 = 0.727272... Or if you prefer fractions: 275(8/11) = 200
Now running the same equation on the height yields:
183(8/11) = 133.090909...
It looks like, under the normal run of things, the partial pixels are cropped, but during the transition the partial pixels aren't being cropped, and the image is warped slightly to show the partial pixels within the same height.
Cropped down to 133px:
Not cropped and slightly warped:
Now that we have a good hypothesis on what's causing the problem, on to the solutions:
You can hard code the height of the image:
Working Example
.link-box .image img {
transition: all .2s ease-out;
width:200px;
height: 133px; /* manually set the height */
}
Or if you would rather not hard code the height, you can also fix the issue with an anti-alias hack, just add a box-shadow.
Working Example
.link-box.large:hover .image img {
opacity: .65;
box-shadow: 0 0 0 #000; /* add a non-visible box-shadow */
}
Or if you're concerned about the cross-browser compatibility of using a box-shadow, you can also use a transparent border:
Working Example
.link-box .image img {
transition: all .2s ease-out;
width:200px;
border: 1px solid transparent; /* add transparent border */
}
Works good on my Firefox.
Anyway you can try to add some special attributes that will prepare the browser for the transition and actually render the element with possible transformation in mind.
Such an attribute is transform: translate3d(0,0,0);
Like this :
.link-box .image img {
transition: all .2s ease-out;
width:200px;
transform: translate3d(0,0,0);
}
.link-box.large { position: relative;}
.link-box.large:hover .image img { opacity: .65; }
i got a little question when using the transition-effect with the property display:
I am testing on Safari:
input.input_field {
display:none;
transition-property: display;
transition-duration: 2s;
-webkit-transition-property: display; /* Safari */
-webkit-transition-duration: 2s; /* Safari */
}
input.input_field_active {
display:block;
}
But this example doesnt work for now, anybody knows why i cant use the the property : display??
Greetings!
You can only perform a transition on a scalable property, i.e. a numerically defined property (which may or may not have units of measurement) which exists within a range for which any two points are related. The reason for this is that in order to perform a transition the browser takes the starting point and ending point provided then extrapolates the interim keyframes- producing the resulting animation.
The display property is not scalable, it is simply 'on' or 'off', indeed more specifically it has a number of properties which arent related on any form of scale. As such, the interim values cannot be extrapolated. You can also look at it like this, display is also a layout and not visual style- although it does have visual connotations. You can only perform transitions on visual styles.
Depending on what your requirements are, you can perform a transition on opacity or height (or width).
Demo Fiddle of alternate transitions
You can use a combination of visibility in place of display and the use opacity as a fade effect.
visibility is transtionable although it also only has an on / off state BUT you can use a transition delay to affect it.
JSFiddle Demo
HTML
<button>Hover</button>
<div class="wrap">
</div>
CSS
.wrap {
width:100px;
height:100px;
border:1px solid grey;
background-color: #bada55;
margin-top: 25px;
visibility:hidden;
opacity:0;
transition: visibility 0s linear 0.5s,
opacity 0.35s linear;
}
button:hover + .wrap {
visibility:visible; /* show it on hover */
opacity:1;
transition-delay:0;
}
I need to change the background-color from red to transparent.
This change should occur when I hover over a div.
The reason is why I need it transparent is so I can show an absolute positioned div under the main div, in other words, when I hover over the parent div, I need to show the child div.
When I move away the cursor from this div, I don't want a reverse-transition, I want the background to stay transparent, I want the blue div to always be there after I move away the cursor.
Since I need a PURE CSS solution (No JS/JQuery), I came into the CSS3 Transition.
<div id="parent">
<div id="child">
</div>
</div>
This is a fiddle (Firefox).
#parent
{
background:red;
-moz-transition:background 1s;
}
#parent:hover
{
background:transparent;
}
I thought about doing this with animation, since I can fake this by giving it a temporary duration to stay transparent, for example.
0% {background:red;}
1% {background:transparent;}
100% {background:transparent;}
But then animation will stop when I move the cursor away.
Note: This may sound ridiculous or stupid, but my intention is bigger than this, this is just one small example.
Take a look at the transition-delay property.
#parent { transition-delay:999999s; }
#parent:hover { transition-delay:0s; }
Fiddle
This way, the hover animation will happen instantly (0s) while the transition to the initial state will only happen after 277 hours without leaving the page. You can increase the value a bit further if necessary, though I believe this value is enough for a real world page. =]
I don't think it's possible with pure CSS. As a compromise you can use JavaScript to add a class to the element and then handle all visuals with CSS.

HTML
<div class="effect">Hover me</div>
CSS
.effect {
background-color: red;
-webkit-transition:background 1s;
transition:background 1s;
}
.effect.anim-done {
background-color: transparent;
}
JS
$('.effect').mouseenter(function () {
$(this).addClass('anim-done');
});
use below code to transiton from red to transparent. and please change 'object' to the class of your object
.object {
background-color: red;
-webkit-transition:background-color 1s linear; /* for webkit supported browsers */
-moz-transition:background-color 1s linear; /* for old mozilla browsers */
-o-transition:background-color 1s linear; /* for opera browsers */
transition:background-color 1s linear; /* for css3 supported browsers */
}
.object:hover {
background-color: transparent;
}
