I'm not sure if this is more of a jQuery, CSS, or browser-related question, but this is what I've been wondering:
In the jsfiddle/code below, the animation starts off by displaying the word "this" pixel by pixel in the animation, but after that it does not show the text of the expanding span until the entire word is rendered; why is that? Also, can it be changed to be like the animation of the first word?

var opts = { "easing" : "linear", "duration" : 4000, "queue" : false};
$("#mask").animate({"width" : width}, opts);
$("#maskBg").animate({"width" : width}, opts);
});
</script>
<body>
<span id="mask">this is some text to demo with</span>
<span id="text">this is some text to demo with</span>

The browser I've been using is Chromium Version 31.0.1650.63 Built on Debian 7.2, running on Debian 7.3 (238485).
Thank you very much!
It's because the words wrap to a new line during the animation. You could solve this by adding white-space:nowrap to the #mask element, thus preventing this default behavior from occurring.
UPDATED EXAMPLE HERE
#mask {
z-index: 3;
position: absolute;
float: right;
width: 0;
height: 20px;
color: white;
margin:0;
background-color: black;
white-space:nowrap;
}

First of all, you can find a simplified demo of my code in this JSFiddle and also below the question. I found that my problem happens the way I describe it in Google Chrome, so if you plan to try and fix the bug, please use that browser. I apologize if the code is not very well simplified; please consider that this is a snippet from a bigger project.
I'm working on a webapp that uses JQuery and GreenSock's TweenLite for animations.
This app consists on some menus that control everything, that are transitioned between using the bodyChange() function. This function has two parameters:
nextOrPrev, that runs one animation or another based on the value
provided ("next" or "prev"). Only the "next" animation is done yet, but that is not important for now. The "prev" animation, not yet used, just emits an alert("prev").
bodyFunction. The function provided will fill the body with the elements necessary for that menu, and the wrap them in a #bodyWrap.
In the demo I provide you with there are only two menus: The first one, mainMenu, with only a #playButton. When you click it, the bodyChange() function is called with the following parameters: ("next", playSettingsBody), playSettings being the second menu.
This is the problem: when you click the playButton, the button goes up a on the screen and then executes the TweenLite animation. I can't see, however, why does the button "jump up", instead of staying in the same place and execute the animation. This is probably due to a small mistake. What is it?
Thanks for any help.
mainMenuBody();
function mainMenuBody() {
$("body").append(
//BUTTONS
"<div id='playButton' class='mainButton'><div class='buttonText mainButtonText text'>PLAY</div></div>"
);
//WRAP
$("body").wrapInner("<div id='bodyWrap'></div>");
//BINDS
$("#playButton").bind("click", function() {
bodyChange("next", playSettingsBody);
});
}
function bodyChange(nextOrPrev, bodyFunction) {
switch (nextOrPrev) {
case "next":
//ANIMATION AND BODY CHANGE
TweenLite.to($("#bodyWrap"), .4, {
ease: Power2.easeIn,
transform: "rotateY(90deg)",
onComplete: function(){
$("body").empty();
//NEW STUFF

TweenLite.from($("#bodyWrap"), .4, {

This problem is caused in your .mainButton class. Your code looks a little like this.
.mainButton {
position: absolute;
top: 150px;
bottom: 0;
//rest
}
By removing the line bottom: 0; your JSFiddle now works as expected. However, if you remove the line top: 150px; instead and leave in the bottom: 0 the problem still occurs. Unfortunately, I cannot provide an explanation for this. It might be worth posting a question on the GSAP forums inquiring about why this occurs works when positioning using bottom but not when using top
Edit
Since you need bottom: 0 and I wasn't able to fix your code I wrote an example which works using Timeline, a GSAP plugin. You can see this JSFiddle or the code example below.
var tl = new TimelineMax();
tl.pause();
tl.fromTo($("#click"), 1, {rotationY: 0, ease: Power2.easeOut}, {rotationY: 90, transformOrigin:"right", ease: Power2.easeOut})
.set($("#click2"), {css:{display: "table"}}, "-=0.6")
.fromTo($("#click2"), 1, {rotationY: -90, ease: Power2.easeOut}, {rotationY: 0, transformOrigin:"left", ease: Power2.easeOut}, "-=0.6");
$("#click").click(function() {
tl.play();
});
$("#click2").click(function() {
tl.reverse();
});

Im trying to do a slider menu, i have a div with a tape background, all is working fine when it's animating to the left by the background-repeat, but when it is animating to the right and it get to the left border of the background it get disappears because background-repeat doesn't repeat to the left, just to the right.. There's way to make the background repeat to the left?
And the list inside the "slider" div doesn't move at the same velocity of "slider" div
Here is the HTML code
<!DOCTYPE html>
<html>
<head>
<title>Prueba</title>
<link type = "text/css" rel = "stylesheet" href = "PruebaIndex.css">
<script type = "text/javascript" src = "jquery-2.1.4.js"></script>
<script>
$(document).ready(function(){
var mode = 0; // 0 Left - 1 Right
autoSlider();
function autoSlider(){
mode = 0;
$("#slider").animate({left: "-=60px", width: "+=60px"}, 'slow', 'linear', autoSlider);
}
function slideLeft(){
mode = 1;
$("#slider").animate({left: "+=60px", width: "-=60px"}, 'slow', 'linear', slideLeft);
}
$("#slider").mouseover(function(){
$("#slider").stop();
});
$("#slider").mouseout(function(){
if(mode === 0)
autoSlider();
else
slideLeft();
});
$("#Left").mouseover(function(){
$("#slider").stop();
autoSlider();
});
$("#Right").mouseover(function(){
$("#slider").stop();
slideLeft();
});
});
</script>
</head>
<body>
<div id = "wrapper">
<div id = "slider">
<ul>
<li>1</li>
<li>2</li>
<li>3</li>
</ul>
</div>
<div id = "Left">
Left
</div>
<div id = "Right">
Right
</div>
</div>
</body>
</html>
And the CSS code
*{
padding: 0;
margin: 0;
}
#slider {
padding: 0;
left: 0px;
background-color: black;
background-image: url("http://s11.postimg.org/msh93rl8z/Tira_Fotografica.png");
background-repeat: repeat-x;
width: 800px;
height: 304px;
position: relative;
overflow: hidden;
}
#wrapper {
width: 800px;
height: 1000px;
margin: 0 auto;
text-align: center;
overflow: hidden;
}
#Left {
width: 100px;
height: 100px;
position: absolute;
color: white;
background-color: black;
margin-top: -200px;
margin-left: -100px;
}
#Right {
width: 100px;
height: 100px;
position: absolute;
color: white;
background-color: black;
margin-top: -200px;
margin-left: 800px;
}
#slider ul {
list-style: none;
}
#slider ul li {
display: inline-block;
width: 200px;
height: 200px;
position: relative;
background-color: white;
margin: 50px 10px 0px 0px;
}
I tried to put the code on JSFiddle but it doesn't run..
Sorry for my bad english
it works. see here: https://jsfiddle.net/cLv4hLfy/
take a look at the #slider element.
this values are annoying ;-)
<div style="left: -5863.5px; width: 6663.8px; overflow: hidden;" id="slider">
left is decreasing and width is getting bigger and bigger.
when the slider goes to the opposite direction left gets bigger and width convergates to 0px.
[EDIT]: so the background is not animated. the div is animated. what about fix the div and animate something in the div. you could do something also with background position when its repeated.
I am totally new to jssor, and a less than novice coder. I just discovered the jssor carousel slider today, and I have been fooling around with it for probably 10 hours.
I have managed to solve most of my issues by reviewing other questions on this site, but I have been running around is circles for the past several hours.
First off to clarify, I love the Slider and it's ability to scale, but I need it to be more basic, and somewhat stay where I put it. :) I think after many hours I have got it to stay in one place just under my navigation, and it seems to be good there (although I probably did the the worse way possible.
My main issue now is that it seems to work perfect in IE, and on my native android cell browser, but on Chrome and Safari, the carousel won't keep its height. My photos are # 200x180, and in IE11, they appear to be the proper size. In the other browsers, the slider is only showing to be about 1/2" high.
My pages are PHP, and I call the slider page onto my home page with an "Include" statement (sorry, I seriously green). Now the code I pulled off of jssor.com does have some html references, so that could be giving me some issues, as well.
You can check it out live at (SilverScreenCollectibles.com). I've also pasted the code below (that I am using on my PHP page) so that you can see how bad I am at this.
I would really appreciate any assistance that anyone out there could offer.
Thanks,
Bill

I'm trying to put together a site that has a welcome-type screen followed by a header/navigation that scrolls to the top of the page and is then fixed, remaining at the top of the page as the user scrolls on. The solution I have works in most browsers, except in the desktop touch version of Chrome I can't stop the header/nav from bouncing around once it reaches the top. I've looked at at least 10 Stack Overflow questions that address this problem, and I've tried a lot of different tutorials and plugins but none of them seem to work for me. I know it's possible because the technique appears on http://laravel.com, and the header/nav is ROCK-SOLID when it reaches the top and becomes fixed. This is what I have now:
html {
height: 100%; }
body {
height: 100%; }
#welcome {
background-color: grey;
height: 100%; }
#header {
background-color: white;
box-shadow: 4px 4px 4px #888888;
height: 90px;
opacity: .93;
position: absolute;
width: 100%; }
#header.fixed {
position: fixed;
top: 0;
width: 100%; }
#nav {
position: absolute;
bottom: 30px;
right: 2%; }
#nav a {
color: black;
letter-spacing: 1px;
line-height: 1.25em;
padding-left: 17px;
text-decoration: none;
text-rendering: optimizelegibility;
text-transform: uppercase; }
#about {
height: 2000px; }

May be jquery toggle make it.
$(document).ready(function() {
$(document).scroll(function() {
var top = $(document).scrollTop();
var viewport = $("#welcome").height();
if (top >= viewport ) {
$('#header').addClass("fixed");
} else if ($('#header').hasClass('fixed')) {
$('#header').removeClass('fixed')}
});
});

I think this is working solution.
http://jsfiddle.net/molo4nik11/zvom6o5w/3/
#header {
background-color: white;
box-shadow: 4px 4px 4px #888888;
height: 90px;
opacity: .93;
position: relative;
width: 100%;
}
#header.fixed {
position: fixed;
top: 0;
width: 100%;
}
It has been a long time, and this is no longer an issue, but at the time chrome was not able to keep this header in place without it appearing "jumpy". I was able to fix it by adding
-webkit-transform: translateZ(0);
to the .fixed class. Although this didn't have any bearing on the visual styles that were applied, using the transform property would cause chrome to treat it as a 3d element and devote more resources to it.
As I mentioned before, this doesn't seem to be an issue anymore, and I have since been able to remove this hack without the old problem recurring.
What I am doing wrong?
When you click on class divtop, it should show a div popup in the middle of the page. At that time back page should become not clickable. escape or a button in popup will close it.

Fiddle
I added some CSS to your #popup and it's now all in the CSS (not inline in the html). Changed also your jQuery animate to 50px, instead of just 50.
I think you have small adjustments to do to the CSS, like in .localmenu I'm not sure why you have both padding-top: 25px; margin-top: 100px;.
CSS
#popup {
position:absolute;
display: none;
float: left;
left:30%;
z-index:1;
}
#popoverlay {
position: fixed;
display:none;
top: 0;
left: 0;
width: 100%;
height: 100%;
background-color: #000;
opacity: 0.5;
}
jQuery
$(document).ready(function () {
$('.divtop').click(function () {
$('#popoverlay').show();
$('#popup').show().css("top", "500px").animate({
top: "50px"
}, 200);
$('.mainContent').css("background-color", "grey");
});
$('#btnHide').click(function () {
$('#popup').hide();
$('#popoverlay').hide();
});
});
HTML
<div class="appContent">
<div class="maincontent">
<div class="divtop">Top</div>
<div class="divtop divbottom">Bottom</div>
</div>
<div id="popup">
<div class='localmenu'>Text in Div Popup
<br/>
<button id="btnHide">Close</button>
<br/>
</div>
</div>
</div>
To get it to work properly, even if there is a vertical scroll bar, you have to use position "fixed". Place popup as a direct child of body and make it's position: fixed, and width and height 100%. Place localmenu as a direct child of body as well. Working example at jsbin.
Html:
<div id="popup">
<!--// This is to stop the user from interacting with the content in the back
// and to give a visual clue about that
-->
</div>
<div class='localmenu'>
<div>
Text in Div Popup<br/>
<button id="btnHide">Close</button><br/>
</div>
</div>
<div class="appContent" >
<div class="maincontent" >
<div class="divtop" >Top</div>
<div class="divtop divbottom" >Bottom</div>
</div>
</div>
CSS:
//Use opacity to give a visual clue. Please note that this doesn't work in -all- browsers
#popup {
position: fixed;
width: 100%;
height: 100%;
display: none;
background: black;
opacity: .5;
top: 0;
left: 0;
}
//This is just to be able to center the actual menu
.localmenu {
top: 20%;
left: 0;
width: 100%;
position: fixed;
height: 150px;
display: none;
}
.localmenu > div {
border: 1px solid blue;
background: #fff;
margin-left : auto;
margin-right: auto;
width: 300px;
height: 150px;
}
Javascript: (This is mostly the same, although I removed the animate, because I don't know exactly how it works and it needs to end at 'top: 0'. As localmenu and popup are seperate, we show them seperate as well.)
$(document).ready(function() {
$('.divtop').click(function() {
$('#popup').show().animate(200);
$('.localmenu').show();
//$('.mainContent').css("background-color", "grey");
});
$('#btnHide').click(function() {
$('#popup').hide();
$('.localmenu').hide();
});
});
To block the div tags at the back from being clickable:
Add a div with the following style in your HTML. Im gonna call it overlay.
.overlay {
width: 100%;
height: 100%;
background-color: #000;
left: 0;
opacity: .8;
position: absolute;
top: 0;
z-index: 10000;
display: none;
}
This will essentially cover up your page when shown up.
To center your popup:
I added some extra styles to #popup and removed some from .localmenu. You were missing position: absolute and z-index, added those in. (z-index of popup must be > z-index of overlay)
#popup {
background: #fff;
position :absolute;
left : 40%;
width : 300px;
height: 600px;
height: 150px;
display: none;
z-index: 10001;
}
.localmenu
{
border: 1px solid black;
}
Then, in your JS,
In your animate method, I changed 50px to 30% to center div#popup
Added code to hide and show .overlay along with #popup.
After the changes,
$(document).ready(function () {
$('.divtop').click(function () {
$('#popup').show().css("top", "500px").animate({
top: "30%"
}, 200);
$('.overlay').show();
});
$('#btnHide').click(function () {
$('#popup,.overlay').hide();
});
});

Try this:
$(document).ready(function() {
$('.divtop').click(function() {
var div = $('.appContent');
$('.localmenu').css({'margin': '200px auto'});
$('#popup').show().css({top: "500px", position: 'absolute', width: div.width(), height: div.height()}).animate({top: 0}, 200);
$('.mainContent').css("background-color", "grey");
});
$('#btnHide').click(function() {
$('.mainContent').css("background-color", "");
$('#popup').hide();
});
});
