parallax

I have been reading a lot about jQuery parallax and I just don't get it at all. I want to do the same as this site: http://www.tokiolab.it/#/ As you can see the first page is an animation which is really easy but when you scroll the next page starts covering part of the first one. Can someone help me a bit, I know you need to use z-index but how do you achieve that effect - it seems to not be that difficult, maybe a fixed background or a fixed div, any ideas? Thanks alot! Thanks in advance! 来源： https://stackoverflow.com/questions/10143340/how-to-do-the-parallax-effect-similar-to-tokiolab-it

I'm facing a challenge of creating an introduction view, something like the "Cleanio" app ( https://itunes.apple.com/fr/app/cleanio-pressing-la-demande/id885856031?mt=8 ). Here is how it looks like: So, the background and the overlay are moving independently and not in the same speed. Does anyone have a start point how to realize that? Yep. What you need is two UIScrollView s. These should both be subviews of the main view (not contained in each other. The bottom one has your image in it and the top one has the content. Call them imageScrollView and contentScrollView . Become the delegate of

This is not strictly a programming question but more "how to accomplish this" question. I am curious (and working on an app that will probably require this) how is left-right parallax scrolling implemented. To know exactly what I mean check the Yahoo Weather app (it's free - no worries there). Are they using just one view controller or a separate controller for each view that is shown there? What is the easiest way to implement this? I have found this topic here which kinda explains it a bit but when are they getting information from their servers? Is it when the views are changed or at the

I have some jQuery listeners setup as follows: $(document).scroll(function() { if( $(this).scrollTop() < change1) { updateBarChart('valuem', 'opencomparison'); } else if ( $(this).scrollTop() > change1 && $(this).scrollTop() < change2) { updateBarChart('valuef', 'opencomparison'); } else if ($(this).scrollTop() > change2) { updateBarChart('valuem', 'remove') //updateSteamChart('','steam') } }); Straightforward enough. Some charts are updated when scrolling changes. My issue is, this is sending too many function updates. I'd like if there were a way to throttle the .scroll(function() {}) That

The website is temporarily hosted here . I used the Pure CSS Parallax example here . All the HTML, CSS and JavaScript should be viewable under View Page Source. The parallax effect works beautifully in Chrome. In Firefox, the effect works but background images start to disappear when I scroll past a certain point! You can checkout http://caniuse.com/ it shows you what every browser supports or not. Every browsers is different as you know, there might be elements on Edge and FF that might not be supported like they are on Chrome. 来源： https://stackoverflow.com/questions/37146084/css-parallax

I would like to make the background image move slightly on the X and Y axis when the mouse is in the "landing-content" DIV, it should move with the movement of the mouse. it should move inverse. EG. Mouse move down, "landing-content" image moves up. HTML <div id="landing-content"> <section class="slider"> <img src="http://i.imgur.com/fVWomWz.png"></img> </section> </div> CSS #landing-content { overflow: hidden; background-image: url(http://i.imgur.com/F2FPRMd.jpg); width: 100%; background-size: cover; background-repeat: no-repeat; max-height: 500px; border-bottom: solid; border-bottom-color:

I'm trying to create a Parallax effect on a UIView inside a UIScrollView. The effect seems to work, but not so well. First i add two UIView sub-views to a UIScrollView and set the UIScrollViews contentSize. The Views sum up and create a contentSize of {320, 1000}. Then I implemented the following in scrollViewDidScroll: - (void)scrollViewDidScroll:(UIScrollView *)scrollView { CGFloat offsetY = scrollView.contentOffset.y; CGFloat percentage = offsetY / scrollView.contentSize.height; NSLog(@"percent = %f", percentage); if (offsetY < 0) { firstView.center = CGPointMake(firstView.center.x,
