JSSOR drag does not work in responsive mode - slider

MOBILE ISSUE ONLY. VIEW ON YOUR PHONE.
I have complete working jssor implementation.
See here : http://www.followupapp.co/learn/learnkonvav2.html
However I took a responsive template and added above code to it. The dragging does not let me scroll past all the items.
See the issue here: http://www.followupapp.co/learn/comply.html
The code can be viewsourced.
I don't fully understand jssor.

You placed jssor slider in <div class="card-block"> element.
And there is 1.25rem padding as below,
.card-block {
-webkit-box-flex: 1;
-webkit-flex: 1 1 auto;
-ms-flex: 1 1 auto;
flex: 1 1 auto;
padding: 1.25rem;
}
Please remove the padding: 1.25rem; to solve the problem.

macOS Safari: fixed background attachment misplaced with parent translateX and left

I have a div, that has full width (100vw) and used a translate in order to place it centered. This is because it’s parent has no full width. If I now add a child with a background image and background-attachment: fixed;, this background image is misplaced in Safari on macOS.
It seems to me that the background image is placed as if the translate on its parent is not active (and thus shows only the right half of the image, since the left part is hidden.
.alignfull {
left: 50%;
max-width: none;
position: relative;
transform: translate(-50%);
width: 100vw;
}
.background {
background: url("https://via.placeholder.com/1800x800") fixed center center / cover;
height: 400px;
width: 100%;
}
<div class="alignfull">
<div class="background">
Test
</div>
</div>
I already tried to change many things but don’t get it working. It seems to be a bug in Safari, but hopefully anyone has an idea how to fix it without waiting for a fix from Apple.
Since the .alignfull is used in rather many places, it’s currently no option to change its CSS.

ListView in WinJS jumps back when height and width specified on listItem

I'm trying to achieve something very simple with WinJS. I want the items in a listView to occupy the full height of the viewport.
I can achieve this by overriding the default styles for the listView like this:
.win-itemscontainer {
width: 100% !important;
height: calc(100vh - 1px) !important;
}
.win-horizontal .win-gridlayout .win-container {
height: calc(20% - 1px);
margin: 0 0 1px 1px;
outline: none;
}
.win-listview {
height: 100vh;
margin: 0;
padding: 0;
}
.win-listview .item {
width: 250px;
}
This works fine and renders 5 rows of list items. The list then scrolls if the number of items exceeds the containers width.
However, there are some very odd behaviours occurring. If I scroll to the very end of the listView, something causes the scroll position to jump back making the last row in the listView unattainable because the jump prevents me from ever reaching it.
Is there a better way of achieving what I'm after or is there a way to fix what I've implemented?
I was never able to sufficiently answer this so I switched from a listView to a repeater which gave me greater control over the markup and CSS.

Fixed attachment background image flicker/disappear in chrome when coupled with a css transform

I am currently doing a parallax website theme. The background images need to be attached as fixed for certain 'div's and 'section's to avoid jquery indulging in everything. The problem was the background images of the tags below any animated item disappeared while the transformation is being done, only on Google Chrome. Remedy?
This has been a very common unsolved mystery. Recently I had the same problem, and '-webkit-backface-visibility: hidden', proved to be less than useless (on my 'fixed' attached background), since the background just disappeared when it was set. (Additional Info: the reason is that when the background is set as fixed, it is almost similar to putting a fixed 'div' in the background and setting the original div background to be transparent. Hidden backface does the obvious).
To solve the current problem, try setting the 'position' propery of the element as 'static', or if you have given it some other value, namely 'relative', 'fixed' or 'absolute', just remove those.
If you don't remember setting the position property, and the problem still persist, my suggestion is that you use a debugging tool on chrome or firefox, to
make sure there are no manually set values to the 'position' property other than
'static'.
Just spent half an hour searching... Thought this could make it easier for you... regards. :)
Same problem here. I had a sticky header using position:fixed; that flickered in PC Chrome 34. I tried the solutions in this thread, position:static; in the parent broke other parts. But I know adding -webkit-transform: translate3d(0,0,0); basically makes Chrome turn that html into a layer so that it won't get repainted. That worked for me.
element {
position:fixed;
top:0;
left:50%;
width:960px;
height:50px;
margin-left:-480px;
-webkit-transform: translate3d(0,0,0);
/* ...all other CSS... */
}
UPDATE
future-friendly answer is to use the will-change property to create a layer!
W3 specs
CanIUse
MDN definition
element {
position:fixed;
top:0;
left:50%;
width:960px;
height:50px;
margin-left:-480px;
will-change:top;
/* ...all other CSS... */
}
And I'll be honest, this seems like a weird solution to fix the flicker, but in essence it makes the element a layer, same as translate3d().
Maybe a little late to answer, but it seems that the bug comes with the background-attachment: fixed property in chrome. I found a solution changin its value to "scroll". It will cause a jitterin effect on firefox but you can avoid it using a media-browser query in your CSS, something like this:
.yourstellarlayer{
background-attachment: fixed;
}
/*only for webkit browsers*/
#media screen and (-webkit-min-device-pixel-ratio:0) {
.yourstellarlayer{
background-attachment: scroll;
}
}
Hope it helps!
I was having the same issue with Chrome, it seems to be a bug that occurs when there is too much going on inside the page, I was able to fix it by adding the following transform code to the fixed position element, (transform: translateZ(0);-webkit-transform: translateZ(0);) that forces the browser to use hardware acceleration to access the device’s graphical processing unit (GPU) to make pixels fly. Web applications, on the other hand, run in the context of the browser, which lets the software do most (if not all) of the rendering, resulting in less horsepower for transitions. But the Web has been catching up, and most browser vendors now provide graphical hardware acceleration by means of particular CSS rules.
Using -webkit-transform: translate3d(0,0,0); will kick the GPU into action for the CSS transitions, making them smoother (higher FPS).
Note: translate3d(0,0,0) does nothing in terms of what you see. it moves the object by 0px in x,y and z axis. It's only a technique to force the hardware acceleration.
#element {
position: fixed;
/* MAGIC HAPPENS HERE */
transform: translateZ(0);
-moz-transform: translatez(0);
-ms-transform: translatez(0);
-o-transform: translatez(0);
-webkit-transform: translateZ(0);
-webkit-font-smoothing: antialiased; /* seems to do the same in Safari Family of Browsers*/
}
This really bugged me and it almost ruined my night. My fix is to set
background-attachment: scroll;
It worked on my project.
Before this, I had it on fixed. Hope this helps.
For me the issue was the styles attach to the parent elements of the div who has the fixed background, I put -webkit-backface-visibility: inherit; to the two main parents of my fixed div.
in my case I was using foundation off-canvas so it goes like this
.off-canvas-wrap{
-webkit-backface-visibility:inherit;
}
.inner-wrap{
-webkit-backface-visibility:inherit;
}
We had a similar problem with a position: fixed; element. This element contained a relatively positioned container, containing an absolutely positioned image. On CSS transition the image disappeared, when the transition was done is re-appeared.
We tried solving the problem by setting the -webkit-backface-visibility to hidden on several elements, including the body element, but this did not help. With the help of this thread we used Chrome's web inspector to fiddle around with elments' position properties and luckily were able to solve the problem without having to alter the site that much. (all we had to do was change the position of the parent of the fixed element to static)
An update almost 5 years in the future... This still seems to be a problem with chrome. I've tried most of the solutions mentioned including adding:
transform: translate3d(0,0,0);
-webkit-transform: translate3d(0,0,0);
and it is not fixing the stuttering issue. adding background-attachment: scroll takes away the parallax effect which is crucial to the UX of the site. The solution above that mentions adding a parent element is not changing anything for me. Any other ideas from people that have had this issue recently? I'm using Gatsby(React) on the front end.
Here is a solution that works (2014.7.11) at firefox 30.0, chrome 35.0, opera 22.0, ie 11.0:
STEP 1: add these lines at .htaccess:
# cache for images
<FilesMatch "\.(png)$">
Header set Cache-Control "max-age=10000, public"
</FilesMatch>
detailed description of this problem and how to fix it:
https://code.google.com/p/chromium/issues/detail?id=102706
STEP 2: add images preloading, for example:
var pics = []; // CREATE PICS ARRAY
$(document).ready(function(){
...
preload(
'/public/images/stars.red.1.star.png',
'/public/images/stars.red.2.star.png',
'/public/images/stars.red.3.star.png',
'/public/images/stars.red.4.star.png',
'/public/images/stars.red.5.star.png',
'/public/images/stars.empty.png'
);
...
$('.rating').on('mousemove', function(event){
var x = event.pageX - this.offsetLeft;
var id = getIdByCoord(x); //
if ($(this).data('current-image') != id) {
$(this).css('background-image', 'url(' + pics[id].src + ')');
$(this).data('current-image', id);
}
})
...
})
...
// PRELOAD FUNCTION TO SET UP PICS ARRAY IN MEMORY USING IMAGE OBJECT
function preload() {
for (i = 0; i < arguments.length; i++) {
pics[i] = new Image();
pics[i].src = arguments[i];
// alert("preload " + arguments[i]);
}
}
P.S. thanks Shawn Altman
My task was to create a page with a parallax effect.
After attempts to fix this by means of CSS I came up with the following solution.
JavaScript:
var isChrome = navigator.userAgent.toLowerCase().indexOf('chrome') > -1;
if (isChrome)
{
var itemArr = $('.slider-title');
$(window).scroll(function()
{
var pos = $(window).scrollTop();
var wh = window.innerHeight;
$(itemArr).each(function(i, item){
var p = $(item).position();
var h = $(item).height();
if (p.top + h > pos && p.top < pos+wh)
{
// items ir redzams
var prc = (p.top - pos +h)/wh ;
//console.log(prc);
$(item).css({'background-position':'center '+prc+'%'});
}
});
});
}
CSS:
/*only for webkit browsers*/
#media screen and (-webkit-min-device-pixel-ratio:0) {
.slider-title{
background-size:auto;
background-position: center 0%;
}
}
.slider-title would be the item with background-attachment fixed.
So I am on Chrome version 40 and still seeing this issue. The workaround which is working for me at the moment is by creating a inner div setting position relative on that div and making it fit the height of its parent and setting the background on the parent div with a background attachment of fixed:
<section style="background-attachment: fixed;">
<div style="position: relative;">
// Code goes here including absolute posiioned elements
</div>
</section>
The problem seems to occur when you have a position relative and background attachment fixed on the same element in my case.
Hope this helps.
This one is late to party but an amazing discovery,
as I can see mostly css framework users, Bootstrap, Foundation (others) , have issues, and I am sure many of you also have scroll to top js functions that show scroll to top button as user starts scrolling down ,
if you have anything like this ( Bootstrap has it built in )
.fade {
opacity: 0;
-webkit-transition: opacity .35s linear;
-o-transition: opacity .35s linear;
transition: opacity .35s linear;
}
.fade.in {
opacity: 1;
}
or you are showing some element via ,
-webkit-transition: opacity .35s linear;
-o-transition: opacity .35s linear;
transition: opacity .35s linear;
or you are adding any kind of element or element class with transition , on scroll down, via js ( animation.css, waypoints.js, velocity.js )
remove transition/class if possible from that element or recheck when that element appears in order to fix the choppy Chrome issue.
Add the transform property to your element with fixed background image. You can have any set position.
#thediv {
width: 100%;
height: 600px;
position: relative;
display: block;
background-image: url(https://cdn.shopify.com/s/files/1/1231/8576/files/hockeyjacket1.jpg);
background-size: cover;
background-position: center;
background-repeat: no-repeat;
background-attachment: fixed;
border: 10px solid black;
transform: translate3d(0,0,0);
-webkit-transform: translate3d(0,0,0);
}

I've had this problem on overlay div below popup window (randomly disappearing in opera 20) - both animated, and activated by script.
<div class="popupwrapper">
<div id="popupdownload" class="popup">
<h1>Test</h1>
</div>
<div class="popupoverlay"></div>
</div>
.popupwrapper {
display: none;
z-index: 9100;
}
.popupwrapper.active {
display: block;
}
.popupwrapper > div {
-webkit-transition: opacity 150ms ease-in-out, -webkit-transform 150ms ease-in-out;
-moz-transition: opacity 150ms ease-in-out, -moz-transform 150ms ease-in-out;
-ie-transition: opacity 150ms ease-in-out, -ie-transform 150ms ease-in-out;
transition: opacity 150ms ease-in-out, transform 150ms ease-in-out;
}
.popupoverlay {
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
width: 100%;
height: 100%;
background: rgba(26,26,26,.9);
opacity: 0;
}
.popup {
position: fixed;
top: 30%;
left: 40%;
padding: 48px;
background: #e6e6e6;
z-index: 9101;
-webkit-transform: scale(1.6);
transform: scale(1.6);
opacity: 0;
}
.popupoverlay.active {
opacity: 1;
}
.popup.active {
-webkit-transform: scale(1);
transform: scale(1);
opacity: 1;
}
Overlay was positioned absolutely (.popupoverlay), but in container which wasn't positioned in any way. I've copied overlay's absolute positioning to parent (.popup) and it works OK.
.popupwrapper {
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
width: 100%;
height: 100%;
display: none;
z-index: 9100;
}
I think problem appears only when positioning of parent elements isn't obvious.
Glad if helped anyone. Regards
Seems to bug in Chrome the moment you add any markup on the element. Try removing the background from such element and give it a position:relative. Inside the element add a new div with the dimensions you need and add the background, just don't add any markup inside of it.
Example:
Current:
<div class="container" style="background-image:url(example.jpg);background-position:center;background-attachment:fixed;background-size:cover;">
<div class="example"></div>
</div>
Corrected:
<div class="container" style="position:relative;">
<div class="added-background" style="position:absolute;width:100%;height:100%;background-image:url(example.jpg);background-position:center;background-attachment:fixed;background-size:cover;">
<div class="example"></div>
</div>
Hope it helps!
Another workaround if you must have position: fixed/relative/absolute maybe because you have an absolutely positioned element inside (as was my case) is to create a wrapper div inside of the flickering div and move the position and background property to that.
e.g.
you had -
<div class="background-flickers' style="background:url('path-to-image'); position:relative">
<absolutely positioned element>
</div>
Possible workaround
<div class="no-more-flicker!">
<div class="wrapper" style="style="background:url('path-to-image'); position:relative">
<absolutely positioned element>
</div>
</div>
I don't have the flicker anymore, apparently the flicker bug does not descend to child containers.
i also had same issues in chrome
it's very simple no need to add any webkit & media tag just follow below steps
1.instead of background:url('path-to-image') set the image like below and set the position as fixed
2.
it will work in chrome as well as IE browser
The issue still persist.
its happening to me on google chrome when i have { background-attachment: fixed; transform: scale(1); transition: transform }
I need background-attachment fixed for parallax effect.
I am scaling my container on scroll.
when tranition and transformed is removed parallax works. Having said that, i can have either one scale effect or parallax effect and not both working on chrome.
Safari doesn't complain and works both like a charm

Safari height 100% element inside a max-height element

I'm trying to figure out why Safari won't read the max-height attribute of its parent as the height. Both Chrome and Firefox will read it correctly, but Safari seems to ignore the parent's max-height and instead grabs the page's full height.
You can see it here
CSS:
body, html {
height: 100%;
margin: 0;
}
div {
height: 100%;
max-height: 300px;
width: 100px;
}
div span {
background: #f0f;
display: block;
height: 100%;
}
Markup:
<div>
<span></span>
</div>
I'm using Safari 6.0.5 on OSX 10.8.5.
This issue happens due to a reported bug in Webkit:
Bug 26559 - When a block's height is determined by min-height/max-height, children with percentage heights are sized incorrectly
This seems to be fixed for Chrome by now, but not for Safari.
The only non-JavaScript workaround that worked for me, is using an absolute positioning on the parent element:
div {
position: absolute;
}
Demo
Try before buy
Similar problem appears on Safari if parent element uses flexbox properties - container won't take 100% of the height.
Another solution (besides position: absolute;) would be to use vh (viewport height) units:
div {
height: 100vh;
}

How to create sticky header bar for a website

I want to create a sticky header bar for a website just like the sticky header on this website (http://www.fizzysoftware.com/) if any on can can help me out with coding or any resource that helps me to create the same. Your reply would be of great help to me.
In your CSS, add
position: fixed;
to your header element. It's just that simple, really.
And next time, try to use right click on something you see on website and choose "Inspect element". I think that every modern browser has it now. Very useful function.
If you want to make it sticky when it's scroll down to a certain point then you can use this function:
$window = $(window);
$window.scroll(function() {
$scroll_position = $window.scrollTop();
if ($scroll_position > 300) { // if body is scrolled down by 300 pixels
$('.your-header').addClass('sticky');
// to get rid of jerk
header_height = $('.your-header').innerHeight();
$('body').css('padding-top' , header_height);
} else {
$('body').css('padding-top' , '0');
$('.your-header').removeClass('sticky');
}
});
And sticky class:
.sticky {
position: fixed;
z-index: 9999;
width: 100%;
}
You can use this plugin and it has some useful options
jQuery Sticky Header
CSS already gives you the answer. Try this out
.sticky {
position: -webkit-sticky;
position: sticky;
top: 0;
}
now add the class sticky to any menu sidebar or anything you want to stick to the top and it will automatically calculate the margin and stick to the top. Cheers.
If you want simplicity in a HTML and CSS option to create a Stiky NavBar you can use the following:
Just create a navbar like this one:
<nav class="zone blue sticky">
<ul class="main-nav">
<li>About</li>
<li>Products</li>
<li>Our Team</li>
<li class="push">Contact</li>
</ul>
</nav>
Remember to add the classes in this case I created a Zone (to separate my HTML in specific areas I want my CSS to be applied) blue (just a color for the nav) and sticky which is the one that gonna carry our sticky function. You can work on other attributes you want to add is up to you.
On the CSS add the following to create the sticky; first I am gonna start with the zone tag
.zone {
/*padding:30px 50px;*/
cursor:pointer;
color:#FFF;
font-size:2em;
border-radius:4px;
border:1px solid #bbb;
transition: all 0.3s linear;
}
now with the sticky tag
.sticky {
position: fixed;
top: 0;
width: 100%;
}
Position fixed meaning it will always be in the same position; and with top 0 I will always be at the top and a 100% width so it covers the whole screen.
And now the color to make our navbar blue
.blue {
background: #7abcff;
You can use this example to create a sticky navbar of yours and play around with the CSS properties to customize it to your liking.
Try This
Add this style to the corresponding
style="position: fixed; width: -webkit-fill-available"
OR
<style>
.className{
position: fixed;
width: -webkit-fill-available;
}
</style>
