Can anyone suggest me please an efficient way to make one container to stick out from bottom of the browser window and be positioned :relative, be scrollable
Can I do it in pure CSS or there is a javascript/jquery for that?
Unfortunately as far as I know you can only do this using JS.
You can get coordinates of the element to which you want to stick, and position it manually. You can update it by "scroll" event using jquery
What do you mean with scrollable exactly?
If you want an element to be fixed at bottom use "position:fixed;bottom:0;" the element will stay at bottom even when scrolling the window.

I have a problem with dragging an element below the viewport. When I try to drag the element below the viewport the page will not autoscroll. As you can see in the image I have provided I am trying to drag an element below. The only way I can scroll below the viewport to drop my element in Firefox is to use the mouse wheel.
If I left click and hold while dragging down on this Stack Overflow page the viewport autoscolls downward. This is how I need my web app to perform.
I'm not really sure where to start with this as it is a paid WordPress plugin called Learndash that not properly coded.
Can anyone point me to the correct solution to this problem?
Thanks.

Edit:
Add a margin below your div to allow space to insert
Or add the CSS properties height:500px and overflow-y:scroll in your div
We all know the 100vh jump on mobile browsers (CSS3 100vh not constant in mobile browser)
In order to prevent that from happening, I wrap the pages scrollable content in a separate div, which works great!
But I still need some fixed elements.
When you now hover the fixed elements and try to scroll, the scroller-div doesn't get scrolled, like body would have with "normal scrolling".
This is obviously really bad and can't stay like this.
It doesn't seem to matter if the fixed elements are siblings, predecessors or ancestors to the .scroll-wrapper. As far as my understanding goes whenever you hover a fixed element and scroll, the browser wants to scroll the fixed elements contents and the scroll-wrapper.
My ideas so far:
Either get a new solution for keeping the address bar from sliding away on scroll.
Or somehow scroll make the browser ignore the attempt to scroll the fixed element and instead scroll the element underneath it, while keeping the fixed element hoverable and clickable.
Or somehow pass on the mousewheel DOMMouseScroll etc. to the .scroll-wrapper
route 2. doesn't is not so promising and I just can't find anything to make route 1. happening, so .. any ideas on how to accomplish the 3. option?
Here is a CodePen to illustrate the problem. https://codepen.io/katerlouis/pen/LQeNbN
strange.. just when the text and CodePen were finished, I found a solution as a suggestion – How to scroll a scrollable div when scrolled on other, non-scrollable div?
solution 3. is possible!
the key is to grab the e.deltaY from the wheel-event on the fixed-elements, and add this to the .scroll-wrapper. If you want to do it with jQuery, the deltaY is "hidden" in e.originalEvent
$(".fixed-element").on("mousewheel DOMMouseScroll wheel MozMousePixelScroll", function(e) {
e.preventDefault();
$(".scroll-wrapper")[0].scrollTop += e.originalEvent.deltaY;
})
Does CSS(3) allow me to stick a DIV with position:absolute over the page and keep it e.g. in the middle of the browser window - even when scrolling?
Currently I re-draw and re-position the DIV again and again when the user scrolls up/down/left/right, but maybe css3 has a better way to achieve the same.
That's what position:fixed is for.
I want a html div which will scroll when user scroll down the page and it will get to fixed position when it's parent tag ends. For example:- See this link http://www.9gag.com/ they have alot to posts on one page. When we scroll one post and go to end of the first post, the title and share buttons become to fixed position and then the second post do the same and same for the next posts. Just exactly like that. How can we do this in Jquery or raw javascript or in css.
Maybe you want to try this plugin: http://labs.anthonygarand.com/sticky/ Sticky is a jQuery plugin that gives you the ability to
make any element on your page always stay visible by making the element to be floated when they has reached the limit.
$(window).scrollTop() will give you the number of pixels scrolled down in the browser, $('postcontainer').offset() will give you the x,y positions of a post container.
So if you bind an event to $(window).scroll() or to the mousescroll, you can check if the postcontainer's offset().top is less than the window.scrollTop. If it is then you start moving the item down relative to the post container. When doing this you need to keep track of the post container's height and the moving element's height to make sure it doesn't go down past the bottom of the container.
So if postcontainer.height - movingelement.position().top >= movingelement.height() then you need to fix the position of the moving element. Do the opposite while scrolling back up.
Hopefully this will get you thinking and starting to kick out some code.
This is the solution for your problem with a simple css property.
use position:sticky to follows the scroll.

Good day.
I need script that will follow the mouse and will scroll content depending on what side mouse is. If left then left, if right then right.
I need it for cases when line of hrefs will exceed width of block, like here http://cloud.ignatynikulin.com/45121918090s3R15193i
If the width is exceed then you will be able to scroll it when you put your mouse to right.
Something that will do that: http://codecanyon.net/item/jquery-mouse-slider/full_screen_preview/143061
I tried that script, but the problem with it is that it needs to rely on some width that I don't have.
Any plugin or ideas suggestion?
Thank you!
Check out the answer here from StackOverflow - it's a perfect solution:
Continuous scroll on hover [performance]
Make the containing div positioned absolute. Then in jQuery, catch the onMouseMove event, calculate the mouse position relative to the containing div (using .width() this works even with dynamic width), and change the left/right property of your containing div according to this.
