I’m working on this website for a client: http://alsite2.stackinjb.com.au/. They want to add ‘skins’ or 'wings' to some pages, as you can see here: https://www.jbhifi.com.au/
If you look at the JB Hi Fi website, you’ll notice that when you scroll down, the top of the ad fixes to the top of the screen. On my site, I can’t seem to make this work.
Any help on how to make this work would be much appreciated.
Cheers
You need some javascript for this. Every time the page is scrolling, you have to check the scroll position against the position of the sticky element. If the scroll position bigger than the position of the sticky element, make it sticky.
Check out Waypoints, this is a nice library for such things.

I am working on building sticky sidebar behavior that will run alongside a vertical feed which is very similar to a facebook feed on desktop web. position: sticky works well for the easy use case where the sidebar is shorter than the height of the viewport. However if your sidebar is larger than the viewport the sidebar needs to have some scrolling mechanism so you can see the bottom of the sidebar as you scroll down the feed.
I am trying to recreate the facebook sidebar sticky scroll here.
The best way to understand the desired behavior is to test out your facebook feed and shrink your screen height so that your viewport is smaller than your sidebar height. I'll try to summarize here:
When your viewport is taller than your sidebar (simple case)
The sidebar behaves exactly as you'd expect with position: sticky. The sidebar stays in the same place and follows as you scroll down and up.
When your viewport is smaller than your sidebar
When you scroll down initially the sidebar scrolls with the feed (they appear fixed together)
When you get to the bottom of your sidebar, it then locks at the bottom and as you scroll down more, the sidebar now appears sticky with the bottom fixed
When you now scroll back up, the sidebar once again appears attached to your main feed, and scrolls up with the main feed. Once you hit the top of the sidebar it's then sticky with the top fixed.
So between those two states (top fixed when scrolling up, bottom fixed when scrolling down), the sidebar scrolls in unison with the main feed.
It's a very nice scrolling experience but very hard to recreate.
I have accomplished the states listed in steps 1-3 above by applying position sticky with a top position, and when you scroll down, using scroll events and some viewport/sidebar height calculations to determine the height difference and adjusting the top css value so it locks when the bottom is lined up with the screen (essentially initialTop - (sidebarHeight - viewportHeight). I cannot figure out steps 4, and 5. The best I could do was transition between the two top values depending on your scroll direction but it's a very bad UX.
I have a sandbox example of a layout here: https://codesandbox.io/s/fragrant-microservice-89b7z?fontsize=14&hidenavigation=1&theme=dark
There's a basic layout with 2 columns (left sidebar and main feed). And there's a react component called StickyScroll which wraps around the column and has all the logic to update the top value. This may be a completely wrong start to a good solution, but any help is greatly appreciated.
I was interested in this as well, so I spent some time studying how fb does it.
It's very clever, my hat off to whichever fb dev originally implemented this.
You have to set the top / bottom css properties on the sticky depending on the direction of scroll, and to keep things from jumping around, you also have to calculate the height of an the element above the sticky, based on scrollTop.
Here is a rough example, which demonstrates the logic in action
I try to make a mock up by your sandbox code based on facebook redesign 2020.
hope you find the answer here. I like this approach because it's not very complex. More precisely, I use the css solution when I have to create a component similar to the Facebook sidebar.So i'm not using your StickyScroll component. Hope you find something.
Codesandbox Independent Scroll
So, the question is pretty basic but I couldn't find an example snippet to start with.
Idea is to have multiple div with full-screen height and upon scroll, the whole of the div scrolls making the user think that they are on same position and content is coming on same position. [ kinda-ish]
I have an example website where such scrolling behaviour is done. here
Just a reference will help me start.
Thanks
I'm working on developing a website but I'm facing an issue.
I'm creating a navigational bar which works 90% - there is just a little issue. When a user scrolls to a certain distance, the navigational bar becomes 'stuck' to the page, scrolling with the user. When the navigational bar is 'stuck', it overlaps the main browser bar.
I'm not too sure why this happens, but I believe that the div above it might be causing the issue.
Ignore the icons to the right of the page, windows eight.
Here's the whole page and stylesheet: https://gist.github.com/TaylerKing/7977e60099c3726938fb
Excuse me for the rusty styling, haven't done pure web design for a year or two;)
The problem is the use of overflow-x:hidden, combined with the navigation bar that is position:fixed. Using position:fixed in unusual situations like this is not as well supported as you might expect.
An alternative would be to use position:relative, and have JavaScript update the top as appropriate.
So in your function navigation rather than adding and removing fixed, you would instead be setting $('.navigation').css('top', window_top - div_top). (remember, the div.navigation has to be position:relative first)
I'm having a little trouble here: ..
Everything seems to work fine (had a small problem with the divs moving around when I resized the window but managed to fix it with a little help from the users of StackOverflow) but I have run into another problem now.
I'm using wordpress for this website with some modifications to a basic theme that I've made. Everything works fine except when you make the window quite small, the horizontal scrollbar appears but when you scroll the horizontal scroll bar you'll notice that the menu overlaps with the content.
How can I make it so that they don't overlap? I tried to make the position of the sidebar absolute instead of fixed, but the menu is supposed to stay there when I scroll vertically.
Not sure how I should go about this... any help would be appreciated!
Thanks!
As I said in my comment, you will need javascript to prevent the content div from overlapping the fixed menu
To point you in the right direction check out this
plugin on github .. its a great plugin using jQuery to accomplish pretty much exactly what you're after ..
Here is the working version using a small bit of jQuery, I hosted it so its easier for you to see:
The only change to the layout you need to make is to set the sidebar-primary div to left: 0; , it nudges that div very slightly to the left, but I think its worth it given that your original problem is solved with just a tiny bit of jQuery. Let me know if it works for your layout ..
I have designed a simple website. The only thing left is to make a small box on the left. But I want to be always visible even when I scroll down. It's use will be something like a small ad. ![floating box][1]
Can you post an example or two? what css is needed for this? (if it's needed)
unfortunately I can't post any images because of I am a new user (I am not allowed to.. and this kinda frustrating)
But I will post an image as soon as possible.
You should apply position: fixed to this box.
Fixed Positioning
An element with fixed position is positioned relative to the browser
window.
It will not move even if the window is scrolled.
Here's a sample: http://www.w3schools.com/css/tryit.asp?filename=trycss_position_fixed
You can read more about CSS positioning here: http://www.w3schools.com/css/css_positioning.asp
Here's a jsFiddle that I baked for your that shows how you can get this working: http://jsfiddle.net/leniel/8ub7s/2/
You can see that even when you scroll, the title is still visible and if you hover it, the ad box will show. Just adapt the CSS to your needs as you want it floated to the left. :)
