I have seen several questions about floating or fixed sidebars on Stackoverflow, but I could find none that covers this scenario.
Take a look at this page as an example: http://msdn.microsoft.com/en-us/library/aa691131(v=vs.71).aspx
When the page is scrolled up, the sidebar also scrolls up with it, until its top edge hits the top of the window. As the scrolling continues, the side bar stays fixed in its place until the page footer reaches up and pushes the sidebar up with itself.
Therefore, the sidebar is always trapped between the page header and the page footer, but within that limitation, it tries to stay visible as much as possible.
This is done by using javascript. I was wondering if you guys have already achieved something like this, or if you know of a solution, that you can share here.
Thank you.
This is a great tutorial on how to acheive this effect through jQuery... http://www.hongkiat.com/blog/css-sticky-position/
It uses jQuery .addClass() to add a class to the element when a certain scroll position is reached.
And the respective .removeClass() when the user scrolls back past.

I'm making a website and want a navigation bar that stays at the top of the screen. I can do this fine but when I scroll to top it goes above header. How do I get it to stop scrolling with the user before the top of the page? I have watched countless tutorials but none seem to work. I think I need JavaScript to unstick the bar at a certain height, but unsure how. Also how do I restick it when the user scrolls back down?
Yes, you will need JavaScript to handle this. It is not too complicated, but you will basically need to add an event handler for the scroll event on the window, and inside the handler you can check the scrollTop of the window to see how much has been scrolled. When it has been scrolled "enough" (usually the height of your header) you can then switch the position of the header to fixed.
You can see a demo about it on the excellent CSS Tricks, and there are many tutorials and plugins that can help with this.
Yes, as danwellman said, you need js.
I have a small code I used in my webpage.
// Highlight the top nav as scrolling occurs
$('body').scrollspy({
target: '.navbar-fixed-top',
offset: 51
});
You need a file like "scrolling-nav.js" or anything you prefer. And in your html, don't forget to call it.
// In the end or in the beggining you call your js file
<script src="...(filepath)/scrolling-nav.js"></script>
There are many more cool possible snippets you can find. This is really to keep the navbar fixed after the offset of '51'. You can also add the smoothed movement to the webpage section after selecting a menu button.. If you have a onepage website, for example. This would also be js.
Good luck. :)
I'm trying to create a responsive website in Dreamweaver with a header and menu which initially scroll and then stick to the top of the page.
The header and menu would need to scroll over the top of a fixed hero image.
This hero image can't be defined as a background as it will be powered by a flexslider script to change the image after a set time.
I would also like the sticky header to possibly shrink down in height when it reaches the top of the page, to reduce the amount of screen space it takes up.
I've found a number of sticky menu examples on-line and some seem to have the annoying trait where the content directly below the menu disappears behind it at the point at which the menu sticks to the top of the screen. I would like to avoid this.
Please find a Mock-up of what I'm looking for here
Obviously, all of the above won't be acceptable on a mobile device.
So for mobiles, the header would need to scroll out of the way, leaving just a hamburger style menu fixed at the top of the screen.
I have found a number of examples on-line with elements of what I require, but nothing yet that combines everything.
I've tried cutting and pasting code from different sources, but haven't yet achieved the desired effect.
I don't know if what I'm asking for is workable, but I would appreciate if anyone could point me to examples of how to achieve this (or improve upon what I'm looking for).
Thanks

Use this JS
http://stickyjs.com/
it adds the class is-sticky to the element which you wanted to stick to top. So you can add height in css for is-sticky class. Which in terms will reduce or increase the height of element when it reaches to top as per your requirement.
I have a page that will be responsive and I also want to add a header that appears once the visitor scrolls for a bit. The header will supplant the main header in order to be visible as the user travels down the page.
I think this was a convention that people have used, and I need some help, as i can't really code it from scratch.
Has anyone seen examples or tutorials on this. I've looked but can't come up with it.
Check out the Twitter Bootstrap framework's Navigation header http://twitter.github.com/bootstrap/components.html#navbar
Static top navbar Create a full-width navbar that scrolls away with
the page by adding .navbar-static-top. Unlike the .navbar-fixed-top
class, you do not need to change any padding on the body.
I want a scrolling menu that begins at a certain part of the page (like under the header), but stays there till you scroll down and it hits the top of your browser window, then follows you down the rest of the page.
Anyone have any clue how to do this? I can't find it anywhere on the net. I've seen others similar to it, but none that move to the top of the window.
There's a great example on gmail when you are viewing an email. The toolbar stays at the top of the email box, but once you scroll past the email box, it follows you down the page.
I know that position:absolute;top:0; will make it stay at the top without the fluid motion (I hate it because it looks sloppy).
** edit **
I really only need to know how to detect that the menu div is at the top of your page. I can do a mock thing where if you scroll down how ever far the menu div is, it will start scrolling down, but I'd rather actually get whether the menu div is past the browser window or not.
It's a mixed position of fixed and absolute, you will handle.scroll event and switch between that.
You can find an example here
Creating a floating box which stays within a div
Here is what I am thinking:
I have long web page and when the user reaches the end, I don't want the scrolling to stop just then, but I want to reload the page again from the bottom and continue the scrolling.
Detailed
As the user scrolls to the bottom, I want the top of the website to be removed from the top and placed at the bottom in a smooth way and this effect has be vice versa also. I mean if user scrolls up at the top of the page, then the footer must load at the top and continue in this fashion.
Yes, Infinite Scroll can do this. There is also a jQuery plugin.
Now whether you should do this... that's an entirely different question. Personally I find this behaviour extremely annoying.
