Please have a look at my sample page.
On that page notice the portion with the gibberish text. This is the "content part" which is meant to be scrolled. All other parts are supposed to be fixed.
If you move your mouse over the left navigation or the header and try to scroll, then naturally nothing happens.
How do I make the content part scroll even when the user's mouse is over the header or left navigation or any other fixed parts?
PS. I am trying to imitate Google Plus here. They seemed to have a scroll listener, but the Javascript code is too mangled for me to understand.
I was wrong in my previous conclusion that Google+ is using Javascript for this.
Yesterday broke down their site into pieces using Firebug. Now it is clear that they too are using position: fixed for fixed parts.
Here is my updated sample page. Notice that now we can use keyboard arrows too to move the page up or down. This page is not using any Javascript.

Wondering how I can achieve the following effect on a website I'm building:
Div with 100vw width and 100vh height (we'll call this #container2) hides to the right of the home page (we'll call the home page #container1).
Moving mouse towards the right edge of the page causes #container2 to peek out.
If the user clicks on the visible portion of #container2, it slides all the way to the left, fully obscuring #container1.
The user is now on a new page with a corresponding URL, where they can scroll down and view more content.
I've got the first 3 steps more or less figured out. What I need help with is figuring out the best way to:
Handle the URL transition from site.com into site.com/newpage during the sliding animation
How to dynamically load the new page's content to the #container2 once the page transition happens, so the user can scroll down and see the new pages content if they click into it, but don't have to load the content if they choose to stay on the homepage.
Making it so if someone types or is linked directly to site.com/newpage, they will see the same thing that someone who started on the home page, clicked #container2, and watched the transition animation sees (but without showing a page transition).
I don't have any code snippets to show because I'm not really sure where to start. Any help or direction would be greatly appreciated. If possible, I'd like to use a vanilla javascript solution, as I've managed to make all the other features on the site run without JQuery. If JQuery is the only way to do this though, I'd still love to hear the solution.
There are a lot of ways you could do this. My intuition would be to have only one page that has different url fragments. Your question is fairly broad so my answer will also be broad.
One approach would be to use the target pseudo-class in css. All you need to do is make container2 a link that adds fragment to the end of the url that matches the classname of said container. You could have a some style for :hover that makes the container slide out and some settings for :target that brings the container to the center of the page. Container2 could have have a second section beneath the fold that contains the rest of the content for the page.
You could do something very similar with javascript by adding and removing classes from the various elements, but using the target pseudo class will help with your last bullet point. If a user goes directly to the link with the fragment, they will see the page with that container displayed.
I hope that gives you a place to start. Here is some info about the target pseudo-class.
I am having a weird problem and cannot even diagnose what is causing it. I am working on my professor's website: jurgec.net
The problem is only on the mobile website. If you click one of the links such as "I am an undergraduate student" then scroll down a little bit, and then press back, the website doesn't fully land at the top of the page. You can see a bit of the yellow page at the bottom.
I have a feeling its because each section's height depends on the browser's screen size. And since on mobile chrome, scrolling down causes the URL bar to disappear, it changes browser's height hence ruining the size of the website's sections.
Any help is greatly appreciated!
This is because the back button returns you to the previous "state" of the website you were at. If you scroll down it's going to go to that part where you were when you made the Click.
Does $(document).ready() functions fire after a back button press?? If they do (not sure at the moment) you could do something like this.
$(document).ready(function(){
scroll(0,0)
});
Which if that works shouldn't really affect you because on initial page load you are already at (0,0) so you wouldn't notice any jumping. Not sure if this would work for you, but good luck!
I'm trying to find the best technique for showing a navigation/menu for a mobile site I'm working on. So far all my solutions have flaws, and I was wondering if anyone could point me in the right direction. (You may have to reduce browser window size to make the examples work as intended)
First off, take a look at this "basic" example: http://audunaas.no/menu/problem.html
You'll notice the content is still scrollable while the navigation is open. This is confusing and annoying.
My first attempt at a fix was to set the body to overflow:hidden and position:fixed whenever the navigation is open. Example here: (Had to remove link because maximum 2 links in post)
This, however, causes the body to snap back to the top and "forget" its scroll position. This means you are taken back to the top of the page whenever you open the navigation. Not good.
Lastly, my best solution so far is one where i put all the page content inside a #scroll-area-div with a fixed position taking up most of the screen, and body scroll set to hidden. Example here: http://audunaas.no/menu/
This solves most of the problems in the page itself, but breaks the "memory" of the back button. This means whenever you click back in your browser you are taken to the top of the page instead of back to where you were before you decided to click a link. (Mobile safari seems to be the only browser that remembers scroll position on div's aswell as body)
I can't really think of any more solutions to this, except for maybe some sort of javascript. Does anyone have some experience with similar cases, or any ideas on how to accomplish this?
The solution must:
Prevent scrolling on page content when navigation is open
Preserve scroll position on page content when navigation is open
Remember scroll position on previous page when back-button is used
I am trying to make a sidebar div sit below a header secion, when you scroll down, it will turn into a fixed div and stay fixed until the bottom of the page, once it reaches a footer section, it will stick to the top of it and allow me to scroll down the footer area without seeing it anymore.
There is a perfect emaxple of what I am trying to describe on this site http://madebymany.com/blog/apples-aesthetic-dichotomy
In the left column, it sticks as you scroll down and then un-sticks at the bottom
I am looking for a good way to do this, hopefully an example or tutorial, I realize it is done with javascript changing the divs properties. I have tried searching but all I could find was old outdated articles over 5-6 years old and they only did half the job. I am not sure even what to call this feature?
That web site is using jQuery Scroll Follow.
Note that according to the jQuery Scoll Follow web site...
The Scroll Follow object will remain inside its immediate container.
... hence why the scrolling stops before the comments on your example web site; the element which is scrolling on the page is constrained inside of its parent <aside> element. You can check out the example.
You basically handle the page's scroll event and move the box around.
Most tutorials require jQuery, so get familiar with it. If you want a tutorial, here's a working one: http://designwoop.com/2011/01/how-to-create-a-jquery-sticky-sidebar/.
Why not dissect the code of that website too?
I am currently designing a webpage that is extremely vertical, my idea was that users would not scroll around the page, but only when they clicked on links with internal anchors (href="#someDiv"), the page would automatically scroll down to that section.
So that the elements of the page are organized into bundles, and the user clicks to go up or down to one section of the single page or another.
I've uploaded the page to the following url:
DWS - Prototype
The page is fairly straightforward, and I am using a smooth-scroll jQuery plugin for the automatic scrolling. All I want is for the user to not be able to wander about on his/her own.
I have tried using overflow:hidden, and looked for javascript or jQuery to get this done, but can't seem to find a viable solution. Overflow hidden prevents the page from loading past the screen, so you can't link to the other elements of the page.
I haven't really tested the HTML/CSS beyond Mac OS, but it works fine on Safari, Firefox and Chrome.
You can disable the scroll bar on a page using the following css property
body{overflow: hidden;}
This will disable both the scroll bar and the mousewheel (im not sure about Pg Up and Down Buttons)
While you definitely have an interesting concept I think it will be very hard to pull off the way you're wanting. What happens if I have the height of my browser window set so small that I can't see your Navigation menus and I also can't scroll? Chances are I'm just gonna get fed up with your site and leave.
When users see a vertical scrollbar they expect to be able to scroll up and down. Taking that way from users is more likely to frustrate and anger them as opposed to them thinking 'This is really cool'.
That being said you could load up jQuery and do something like this:
$(document).ready(function() {
$('html, body').scroll(function(e) {
e.preventDefault();
});
});
This should prevent the scrollbar from going up or down. disclaimer: I have not tested this.
I suggest you make the sections (partially) collapsible. E.g. like here.
