I have a website with a very big header that will go out of screen when scrolling (I want this), then I have two columns. I'd like the left column (it's a section at the moment) to remain visible all the time while the right one scrolls down.
position: fixed; is not what I'm looking for, as I would like the left column to scroll until it reaches the top of the screen, and then stay there.
I know this can be done with javascript, but is it possible to do this just using css?

I have a normal prime Ng table which is scrollable vertically. However, if the screen size is too small, I end up with the normal page scroll aswell as the table scroll.
Is there a way around this? To make the table the size of whatever the screen is, with an infinite scroll. So basically the table scroll would turn into the main page scroll at the side of the page? Instead of having two?

Explanation
By default p-table stretches downwards infinitely, unless you limit it's height, in which case it will have a vertical scroll if there's more data than can fit within the height you set.
Moreover, if all your elements together on the page (including the table), don't fit the current view, page will also get it's own scroll.
E.g. I have a menu on top of the page, under it a card with other things, then a table toolbar, then the table, that's a lot of elements and they won't fit within the view, so page will get it's own scroll. Meanwhile your table has scrollHeight of 600px, yet you have data for 900px, it will get it's own scroll too. Boom 2 scrolls.
Fix You can fix it in a few different ways but it all comes down to the desired behavior/look of your page... when I had this prob I just removed height restrictions and let table expand downwards infinitely, it wasn't a problem because: 1- table was the last element of the page from top to bottom; 2- I had paginator to limit size regardless. So I ended up with only the page scroll.
I have a webpage with a horizontal top sticky navbar 60px high.
On my page, I have links to locations on the same page with Link leading to id="someTarget"
My problem is that when the resulting link is clicked, the page scrolls to the target heading, but it is at the very top of the screen, behind my sticky navbar.
How can I specify that the scroll add a 60px cushion so that the target is at the top of the viewable area, not at the top of the screen?
So far I have just been manually adding in my id="someTarget" a few lines above what I actually want to be the target, but this seems a pretty imprecise way of doing it.
If you are okay with using a CSS framework for this, Bootstrap has what you need. There is an offset option that you could use.
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
My navigation bar keeps getting cut off when the browser window gets too small. I have it as position: fixed so that the navigation bar stays in the screen even when the page is scroll down. Doing this though makes it cut off. I also don't want to change the UI to 100%. Because this makes my links go to the next line on the page, but they have borders and it doesn't look professional. I set up a JSfiddle. I think ultimately what I want is it to be fixed vertically, but when people scroll side to side it becomes absolute. I feel that this could be done with javascript, but I have little experience on it. I've seen a few topics on the same subject, but i haven't seen it fixed.
You can adopt responsive menu then. A demo is here. Resize your browser to see how the menu adopts itself based on the available width.
I am trying to create a CSS layout where the page looks like it's in the middle of the forest. There is a left and right div with the background trees, some header divs that show the top of the page with various wildlife, and some footer divs that show the bottom with more wildlife that matches up with the left and right div background images, all of which is positioned using "position: fixed" in CSS.
Then there is content in the middle that is positioned normally and scrollable. That all works fine.
The problem I'm having is that the background forest layout is fixed at 1204x768 but of course some web browser windows may not be that large. Unfortunately while the content will scroll as intended, the fixed position elements will never be shown if they are outside the size of the browser window. Clearly not acceptable.
I've tried setting overflow: scroll and height: 768 on the .body and .html elements in the stylesheet but no luck.
Note that I am positioning everything with top: and left: values in the CSS. I know I could get around this by using bottom: and right: but the problem is that the footer images wouldn't line up.
This may just not be possible in which case I'll have to rework the graphic design, but if it is possible I'd love to know how!
of course some web browser windows may not be that large
Or indeed that small! The likelihood of the browser window actually being exactly the right size to put your decorations on the edges is quite small; that's always the problem with fixed layout.
I know I could get around this by using bottom: and right: but the problem is that the footer images wouldn't line up.
Yes, designing images that can alter their joins in response to page size changes is more work, but it's doable. You would have to export the ‘bird+foliage’ layer and the ‘squirrel+foliage’ layer as standalone transparent images, then lay them over the top of a longer side image.
To make the object edges nice and smooth would require PNG's 8-bit transparency, which would necessitate a PNG-rendering hack for IE6. Not the end of the world though.
Unfortunately while the content will scroll as intended, the fixed position elements will never be shown
Is that a problem? They are only decorational in nature.
I've tried setting overflow: scroll and height: 768 on the .body and .html elements
For this approach you would need to set ‘overflow: auto; height: 768px;’ on a wrapper <div> which holds both your #sidebar-left and your #content.
You could have two pictures: 1) a right that contains the right trees and the bottom footer image and 2) and left image with the left trees. Make the bottom footer much wider than it needs to be and the trees (left and right) much taller than they need to be.
Then set the right picture to bottom: and right: and set the left picture to bottom: left:. This will force the pictures to always be on the outsides of the page, no matter the browser size. Then set the z-index of the right picture to be just behind the left picture. It will then always look like the page will be bordered. Or you can set a firm width and height on the parent container, and they will always be on the border of the container. You can also set a min-width and -height if you need to have a certain minimum sizes.
As for things not being visible at a certain resolution, you're really not going to get around this. You could have two sets of pictures, one for normal resolutions, and one for smaller resolutions. Then you can get the width and height of the browser with $(window).height() and $(window).width() with jQuery, and load the appropriate pictures.
EDIT: After looking at your site, i'm pretty sure the second part of that (setting a fixed width for a container, then putting a bottom right picture and bottom left picture) will work for what you want. That will force the page to be a certain width, and thus have the entire border visible.
