I have a problem with div "transition"\"hover" at my project :
Comverese.
At the section "SUCCESS STORIES" . when you hover the div's , it go up this o.k ,but not stay up when you move the mouse in that div.
What is the problem?
.story1{
position: absolute;
width: 22rem;
height: 12rem;
z-index: 9;
background: white;
padding: 1rem;
-webkit-transition:transform .6s ease-out;
-moz-transition:transform .6s ease-out;
-ms-transition:transform .6s ease-out;
-o-transition:transform .6s ease-out;
transition:transform .6s ease-out;
}
.story1:hover{
-webkit-transform:translate(0px,-200px);
-moz-transform:translate(0px,-200px);
-ms-transform:translate(0px,-200px);
-o-transform:translate(0px,-200px);
transform:translate(0px,-200px);
}
The problem is that your div is not hovered anymore after it translates. The div moved up, and you're now hovering the div below (namely the .quote div) -> the story div comes back down.
One way to fix this is to use a bit of javascript instead of solely relying upon CSS. Adding a specific class on mouseenter and removing it when you're leaving the div below.
Something like the following (note that the JavaScript is a bit simple and should be improved upon to work for every story).
CSS:
.story1.translated {
-webkit-transform:translate(0px,-200px);
-moz-transform:translate(0px,-200px);
-ms-transform:translate(0px,-200px);
-o-transform:translate(0px,-200px);
transform:translate(0px,-200px);
}
JS :
var story1 = document.getElementsByClassName("story1")[0];
var blockquote = document.getElementsByClassName("quote")[0];
story1.addEventListener("mouseenter", function () {
story1.className += " translated";
}
blockquote.addEventListener("mouseleave", function () {
story1.className = story1.className.replace(" translated", "");
}
Edit
A pure CSS solution would be to move the :hover part to .story and style .story1 accordingly when it occurs. As follow:
.story:hover .story1{
-webkit-transform:translate(0px,-200px);
-moz-transform:translate(0px,-200px);
-ms-transform:translate(0px,-200px);
-o-transform:translate(0px,-200px);
transform:translate(0px,-200px);
}
This seems to work just fine when I change it locally to try it on your site.
And the same change can be applied to .float-icon:hover as well. Changing it to .story-icon:hover .float-icon works wonders

Is there a way to transition a div to be visible by making it visible from the top and then going down?
Example:
#div {
visibility: hidden;
transition: visibility 1s (??);
}
#outerdiv:hover #div{
visibility: visible;
}
Yes you can, but you can´t do fades in and out with the display option, because it doesn´t have a intermediate state. If you want to acheve a opacity fade, you must use the css opacity option, and a trigger for the div to call this changes. The code will look like the following:
CSS:
div{
opacity: 0;
transition: 1s;
}
/*in this case I will use hover as the trigger*/
div:hover{
opacity:1;
}
On the other hand, if you want the div to do the fade in at the moment that the web loads, you will need to create a function in js, that will be called at the moment that the page loads, using onload="function()".
I tend to use the following SCSS #mixin for an animation effect to let users know what is interactive on my projects.
#mixin clickAnimation($opacity: 0.5, $distance: -1px, $time: 75ms) {
opacity: 1;
transition: $time ease;
cursor: pointer;
&:hover {
transform: translateY($distance);
opacity: $opacity;
}
&:active {
transform: translateY(2px);
}
}
I'll tend to use it across the site like this:
a:not(.disabled) {
#include clickAnimation();
}
Recently I've noticed a quirky issue with this.
If the user hovers the <a> element on the bottom pixel of the <a>, the <a> will transform up to -1px. When the user clicks the <a>, the :active css state will perform (in this case, translating down to 2px), but the click action will not register. So no click handlers will fire, and no links will cause redirects.
Has anyone had this issue before and know what I could do to fix it?
As requested, here is a fiddle which demonstrates the issue: https://jsfiddle.net/bf9yk0tn/
Apparently, the DOM looses track of the element since its moving from its original position and there's nothing at the time click event occurs (somehow it manages the hover though).
You can go for a workaround like this to fill the void but Im not sure if its the best solution.
a:hover::after {
content: '';
position: absolute;
bottom: -1px;
left: 0;
height: 1px;
width: 100%;
}
Here's the update jsfiddle
I have this div
<div id="view_album">
View Photo
</div>
And a css
#view_album {
text-align: right;
width: auto;
display: inline-block;
background: #005cb9;
color: white;
box-sizing: border-box;
padding: 10px;
-webkit-transition: all .5s ease-in-out;
-moz-transition: all .5s ease-in-out;
-o-transition: all .5s ease-in-out;
-ms-transition: all .5s ease-in-out;
transition: all .5s ease-in-out;
}
#view_album:hover {
width: 100%;
}
Is it possible to animate the width from auto to something? A final width of 100% isn't working but if I set the initial width to a specific value like 100px and so, it works. But I need it auto since the text inside the div, 'View Photo', can be other text, too like something longer than that.
On this site I'm working on:
As you can see, that div with 'View Album' has a specific width of 115px. Then animate to 100%. But if I change the text inside like, 'Abc', which is obviously shorter than View Album and does not need a 115px of width.
That's why I need it auto.
First, change ids to classes, since you are repeating same id for all album covers.
You can use auto width and after site is loaded, run jQuery script and add current width to css:
$(document).ready(function(){
$.each($('.view_album'), function(){
$(this).css('width', $(this).width() + 'px');
}
});
I don't think CSS can animate/do transitioning in the way you want. You have to use script to set the initial width explicitly. However we have to know the width which is calculated by the browser (from the style width:auto after the element is rendered), this can be done easily using getComputedStyle or simply by the css method in jQuery. The important thing here is you have to modify the style via the CSSRule, not via the style property of the element. I'm not sure why it is but looks like that's how CSS works. Here is the script to find the rule #view_album and set the width to a specific value so that the hovering can make it transition well:
var ss = document.styleSheets;
for(var i = 0; i < ss.length; i++){
var rules = ss[i].cssRules || ss[i].rules;
var br = false;
for(var j = 0; j < rules.length; j++) {
if(rules[j].selectorText == '#view_album'){
rules[j].style.width = $('#view_album').css('width');
br = true;
break;
}
}
if(br) break;
}
Demo.
NOTE: Doing so won't set the width:auto on your element any more, so you should not change the text of that element dynamically (I think this is not your use case). If you have to change it dynamically and the width should expand/collapse automatically, you can try setting width:auto on it first before setting the text/innerHTML.
Here is Another version allowing you to change the font-size of the #view_album so that the width is adjusted accordingly.
I'm trying to fade a Modal in when it's clicked, and have the experience be smooth on mobile devices.
I'm setting both opacity to 0 and display to none. Setting opacity alone isn't enough, as it makes the area underneath unclickable.
#Modal {
display: none;
opacity: 0;
transition: opacity 500ms ease 0s;
}
Fade in Code:
$('#Modal').show();
$('#Modal').css('opacity','100');
However, the Modal doesn't fade in, it simply pops into existence.
Setting a setTimeout here works, but who wants a click delay for the fade in?
What's the best way to fade an element in with an opacity transition without chaining together massive properties like z-index, or some such nonsense?
Toogling display property it's bad way for fade element, Similar topics were already processed e.g: CSS3 transition doesn't work with display property
"display:none; removes a block from the page as if it were never there. A block cannot be partially displayed; it’s either there or it’s not. The same is true for visibility; you can’t expect a block to be half hidden which, by definition, would be visible! Fortunately, you can use opacity for fading effects instead."

You should try to do this by deelay like here Animating from “display: block” to “display: none”
or try toogling class like here: http://jsfiddle.net/eJsZx/19/
CSS:
.Modal {
display: block;
opacity: 0;
transition: all 300ms ease 0s;
height: 0px;
overflow: hidden;
}
.ModalVisible {
display: block;
opacity: 1;
height: 50px;
}
Jquery:
$('button').on('click', function () {
$('#ModalId').addClass('ModalVisible');
});
Html:
<div id='ModalId' class="Modal" > content <br> content </div>
<button>show</button>
Why don't you use jQuery's $("selector").fadeIn() method?
The supposedly correct answer above implies that the OP is attempting a transition on display. They are not. Calling show() will set the display property to block. Then setting the opacity should theoretically trigger the transition from opacity:0.
A similar question has been answered here. To quote #WhoTheHellIsThat, the reason the transition is not triggered is...
...because of the way styles are figured out. Style changes are
expensive so they are effectively saved up until they are needed (a
recalc check like .offsetHeight is called or the next frame needs to
be drawn).
However the answer code in that question was Vanilla Javascript, and I couldn't make it work in jQuery. I found another answer that solved it in jQuery, using a class to trigger the transition.
Here is the full CSS...
#Modal {
display: none;
opacity: 0;
transition: opacity 500ms ease 0s;
}
#Modal.fade-in {
opacity: 1;
}
And here is the full JS:
$('#Modal').show(0, function() {
$(this).addClass('fade-in');
});
Here is a fiddle from RoryMcRossan's answer, demonstrating the solution.
I'm have a vertical stack of items to which the user can append one by clicking a button, roughly like this.
<ol>
<li><textarea></textarea></li>
<li><textarea></textarea></li>
</ol>
<a data-action="additem">Add another</a>
I'm trying to write a CSS animation so that when the new li is inserted, the "Add another" smoothly slides down to its new resting place. Fixed height on the li tags is not an option, and I'm trying to avoid using the max-height animation hack because it can have weird layout effects.
I figured out that I could animate margin-bottom from something to 0 and have the desired effect, but I can't figure out how in CSS to express that I want the current height of the element to which this rule is applied. Percentages are measured relative to the width of the element, which isn't what I need here, and I can't think of a clever trick using calc or the like to express what I want to the browser.
Suggestions?
EDIT
I'm using a template with a repeat binding to add the items to the list. The JS only pushes another object into an observable array, and the framework handles the actual DOM insertion. The li tag has on it the following CSS to get it to enter smoothly:
animation: append forwards .5s;
And append is defined as:
#keyframes append {
from {
transform: translateX(10%);
opacity: 0;
margin-bottom: _____;
}
to {
transform: none;
opacity: 1;
margin-bottom: 0;
}
}
Not currently...
I've come up against this frustrating issue a number of times, always trying to either animate a non-numeric value, access a specific property of the current element as an animation value, or animate an unspecified value to a specified one. Generally I always have to fall back to either some form of not-quite-perfect max-height animation (like you've already mentioned) or use a mixture of CSS and JavaScript/jQuery.
For your issue there are a few options, but none are exactly what you're after.
css only version (using duplicated markup and another animation)
http://jsfiddle.net/7m8F9/2/
http://jsfiddle.net/7m8F9/3/ <-- improved version using bottom and position:relative
http://jsfiddle.net/7m8F9/5/ <-- even better version, going back to translateY
One trick often used with CSS-only hacks, is to duplicate markup — in this instance, the link iteself — and place it within parent wrappers that will be turned on or off by different means. The downsides to this method are that you get a rather ugly markup, and in this particular instance a bullet-number that appears jarringly (because of having to move the opacity animation from the li to the textarea).
The benefits of this method however are that by moving the link inside the li you can use -100% on the y-axis with a translate, or another offset method. Oddly though I can't work out what translateY(-100%) is calculating based upon... it doesn't seem to be the parent height, perhaps it is the height of itself. For this reason I've updated the fiddle to use bottom and relative positioning instead, although in Firefox (on mac) this glitches briefly.
It does seem to be that translateY is calculating percentage based on it's own height, so in order to get around this problem I've had to make use of position absolute and force the the link layer to assume the same dimensions as the li... annoying, as it involves z-indexing the textarea above the link, and an internal span to offset the link text, but at least it does work.
The following code works in the latest Firefox, and would work in other modern browsers if all the different browser-prefixes were correctly used to define the animation keyframes, I don't have time to set them all up right now however.
markup:
<ol class="list">
<li><textarea></textarea><a class="add" href="#"><span>Add another</span></a></li>
<li><textarea></textarea><a class="add" href="#"><span>Add another</span></a></li>
</ol>
css:
ol li {
position: relative;
}
ol li .add {
display: none;
}
ol li:last-child .add {
position: absolute;
left: 0;
right: 0;
bottom: 0;
top: 0;
width: 100%;
height: 100%;
display: block;
animation-duration: 1s;
animation-name: slide;
}
ol li:last-child .add span {
position: absolute;
bottom: -20px;
}
.list li textarea {
position: relative;
animation-duration: 1s;
animation-name: append;
z-index: 1;
}
#keyframes append {
from {
transform: translateX(10%);
opacity: 0;
}
to {
transform: none;
opacity: 1;
}
}
#keyframes slide {
from {
transform: translateY(-100%);
}
to {
transform: none;
}
}
javascript version (code triggered translations)
http://jsfiddle.net/7m8F9/1/
The following obviously doesn't take into account the fact that you are using a template engine to power your DOM manipulations, but all the code needs to work properly is a before and after height of the list (to calculate the difference in height), and an event to trigger at the point where the new list item is added.
Sadly it is not yet possible to do this all in pure CSS, at least not as far as I have seen, perhaps once calc has leveled up...? Or perhaps if some way is introduced to reference the current elements dimensions, not just it's offset parent.
It should be noted I didn't have Internet Explorer around to test this with, but all other modern browsers seem happy.
markup:
<ol class="list">
<li><textarea></textarea></li>
<li><textarea></textarea></li>
</ol>
<div class="add">
Add another
</div>
javascript (with jQuery):
function prefix(){
for ( var a = ['Webkit','Moz','O','ms'], i=0, l = a.length; i<l; i++ ) {
if ( document.body.style[a[i]+'AnimationName'] !== undefined ) {
return { js: a[i], css: '-' + a[i].toLowerCase() + '-' };
}
}
return { css:'', js:'' };
}
$(function(){
$('.add a').click(function(e){
e.preventDefault();
var pref = prefix(),
link = $(this).parent(),
list = $('.list'),
lihi = list.height(),
liad = $('<li><textarea></textarea></li>').appendTo(list),
lihd = lihi - list.height();
link.css(pref.css + 'transform', 'translateY(' + lihd + 'px)');
setTimeout(function(){link.addClass('translate-zero transition-all');},0);
setTimeout(function(){
link.css(pref.css + 'transform', '');
link.removeClass('translate-zero transition-all');
},500);
});
});
css:
.transition-all {
-webkit-transition: all 0.5s;
-moz-transition: all 0.5s;
-ms-transition: all 0.5s;
-o-transition: all 0.5s;
transition: all 0.5s;
}
.translate-zero {
-webkit-transform: translateY(0) !important;
-moz-transform: translateY(0) !important;
-ms-transform: translateY(0) !important;
-o-transform: translateY(0) !important;
transform: translateY(0) !important;
}
.list li {
animation-duration: 1s;
animation-name: append;
}
#keyframes append {
from {
transform: translateX(10%);
opacity: 0;
}
to {
transform: none;
opacity: 1;
}
}
redesign version
A number of times I have hit a similar issue, only to find a redesign helps do away with the problem and can often actually improve usability. In your case it may be best to place the "add link" above the list (or top right), or integrate the button as a floating icon somewhere... where-ever you put it, it is best to try and keep it in a static location, moving interaction points can be annoying for users, especially if they wish to add more than one item in quick succession.
The simplest solution that i could think of is this.
When you add a new li element, just append it in the dom.
liMarkup = '<li><textarea></textarea></li>'
$('ol').append(liMarkup);
$('ol').find('li').last().css('display','none');
$('ol').find('li').last().show('fast');
This would work as per your requirement :) I hope it helps.
