Changing URL while displaying page change animation

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.

Member action popup

So I wanted to do for my company's webpage, a thing where are links that belong to people, to make it when you click, you have a little menu where you can choose to send him a message or view his profile..
Before click:
After click:
I tryed to search for it, couldn't find anything of much valuable.. Maybe someone can help me out.

If you're looking for an easy way to do it, I recommend using jQuery (http://jquery.com/) with one of the popup plugins (http://plugins.jquery.com/tag/popup/). It's easy to install, and most of them have a working demo for you to test out before download.
Otherwise, coding a popup window with pure JS takes time.
This general method is to:
Create a hidden div
Position: absolute and play with the z-index so your div will be on top of all other elements.
Set the position to where you clicked, or somewhere around the area of the target.
Take into account the width and height of the window/screen. (i.e. No poing in showing a div that'll appear off screen).
Fill it in with information you need.
Make it appear.

The way I've done things like that in the past is to have a hidden absolute or fixed DIV layer that houses that message menu. Then have a click trigger make that div layer visible and positioned at the current mouse coordinates.
There should be a lot of articles on google telling you how to do the various stages of all those steps.

Dynamic jQuery menu with sliding pictures

I need to make a dynamic jQuery menu for showing products.
There will be one main picture with text and hyperlink on it, taking 60% of the screen, and on the right of it I need three small pictures (one above the other, horizontally) with 20% width of screen (but all together taking same height as the main one).
I need help for the animation. The animation will be next:
the three pictures on the right are sliding up, and the top most disappears, and a new one is appended to the bottom (at the same time as the top most is disapearing). Now, the one that dissapeared becomes the main one.
I've made an easy solution with .slideUp function, but that doesn't actually made the div go up, instead it is just losing it's height until it becomes invisible. It is not the solution I wanted.
Thanks.
EDIT:
I've managed to get some solution with jQuery.sliedUp function, but still I didn't get the effect that the client was asking for.
Now with a little bit more search, I've found that the jQuery UI hide function extension can do the effect I am looking for.
Here's an example: http://jsfiddle.net/WMPRJ/
My problem now is if you click on the top div, while it is sliding up, the bottom div does not follow it up and take its place. I need to do that. Please provide me with a solution.

Append the current main to the bottom of your thumbnails, slide up the top one and remove() it. Take its src attribute and set it to the main image.
Here's some (sorry, not a self-contained example) code that should get you where you're going. If you actually take the time to read it you'll see it does exactly what I described in the first two sentences.
$('.thumb').first().slideUp(function(){
$('#main').attr('src', $(this).attr('src'));
$(this).remove();
});

if this a homework please append homework tag.
I can't provide you with full HTML and javascript, but an idea. You have two blocks. Float the right block;
Left Block - 60%.
Right Block - 20% (float:right)
Define height for Right & Left block and give overflow:hidden for Right Block.
Now define a click function like this.
var nextAnimateImageId = 1;
$("#my_button").click(function{
jQuery("#my_image"+animateImageId).animate({height:'toggle'});
nextAnimateImageId = nextAnimateImageId + 1;
});
My idea is, if you have 5 images, only 3 will be shown becaue of defined height and overflow:hidden property. When you animate the first image to height=0 (which is what toggle does), the 4th image will come up due to the space freed up, giving you a nice scroll up animation.

Tool Tip jQuery to appear outside slide element

I have a jQuery conundrum that I'm not sure can be resolved. Inside a content slider I have absolutely positioned divs creating a tool-tip style pop-up on hover. Because the containing content slider overflow must be set to hidden, the tool-tip pop-up gets cut off where it overflows. I would like the pop-up to display in full when overlapping the slider it is contained within. If anyone has a workaround for this I'd be very appreciative!
Here's a link to my working file from which you can see the problem and the code.
Many thanks for any advice.

Your animation inside 'slidesContainer' relies on overflow:hidden so the large image doesn't stick out of the div and the only way for you to get the balloons pop out is to remove that overflow:hidden and make it visible
I don't think you can have the two at the same time

Right, so I don't think there was a straight forward solution so what I did was change the script to refer to div IDs instead of referring to the 'next' div. I moved the pop-up div's outside the slide element and absolutely positioned them relative to the page rather than the link. It's more long winded but works fine! Just means you need to refer individually to each pop-up div in the script. Thanks for you help anyway!

How do I make an image partially scroll, then stay fixed, then scroll when you pass a section?

I don't even know what I want to do would be called
Please take a quick look at this page:
http://www.philsalesses.com/plasma-pong/
You'll see the title Plasma Pong and an image under it, on the left side. When I scroll the article, I'd like it to stay put while the page scrolls. However, you'll notice when you get the bottom of the page, there is a footer and there wouldn't be enough room for the title and image if I just made it completely static.
I'd like that to stay put until the footer hits, then scroll. When you scroll back up the page, it will scroll a little bit, until there is room, then stay put again. The same effect, but in reverse. Any idea what to look up how I could do this?

Set the titles css position to fixed. Then use javascript to detect a scroll event when certain criteria are met reset it to an absolute position so that it stays above the footer. Then when remove the absolute positioning when the page is scrolled away from the footer. To see a working example go to quirksmode.org. In his articles he has the effect you are looking for.
