Div height to be remaining space of page

I apologize for the poor wording of my title, I am not sure how to explain my question in the most concise way.
I have an isotope JavaScript plugin that filters I use to filter some elements. The plugin works fine, however I added my own "No results" text that appears when there are no results. It functions correctly, however what is not working is the animation.
At the moment, if you are scrolled down on the page, and the results go from multiple shown results to 0 results where my "No Results" code appears, there is an animation glitch where my footer (which I have set using flex display to be at at the bottom of the screen) moves up from the bottom, and then snaps into the bottom.
I have worked out that one possible solution for this may be to give the "No results" text a height that would make all of the contents on the page add up to 100vh. Is there a way to calculate it so that it will be the calculated height of what is left on the page to ensure the min size of the contents of the page are 100vh.
Here are some screenshots of the issue:
This is how it should look the entire time when there are no results. However this only happens at the end of the animation
This is what happens during the actual animation. The page resizes in a strange way where the footer first moves up, leaving the white space at the bottom and only then does it snap down into position.
Attached is the live code of my site, to see what I mean, please first scroll down and then click the "Financial Sustainability" checkbox.

If anyone has any advice at all about this, even on how to explain the question better, I am open to any feedback and suggestions and I really appreciate all of the support.

Change div position ontouchdrag (if such an event is usable)

Basically, I have a web page which is a div inside a div. Let's say that div 1 (the container) is 500px high. Div 2 is 100px high inside of that container. What I want to do is detect the user touching div 2 on the screen (this is a web page on a mobile phone) and as they drag up/down, the div moves with them. I've done some research and have seen this being done using matrix3d and transform y in CSS 3 (but I can't find a good explanation for someone with little experience with this sort of thing such as myself). I want it so that, let's say, the user drags the second div to the bottom and some of the content goes outside of the container div. I don't want it to scroll down, I do want it to disappear... BUT I want it to kind of 'bounce' back into view. So here's the breakdown.
user presses the screen
user drags div 2 which is inside of div 1. As they drag the div, it moves in the direction of their drag.
the user can drag the div right to the top/bottom. If they drag it outside of the container div, that's fine. The container div should not resize or become scrollable and part of div 2 should disappear from view.
when the user releases the drag, the div should bounce back into position. Let's say, if it is dragged too high up, it bounces back to position 100, 100. If it's dragged too far down then it bounces back to 100, 500 (I figure the bounce can be controlled by a CSS transition).
So, does anyone have an example that I can look at to see this in action or a tutorial that will help me understand how I can achieve this? I apologise for not providing any code as a basis to start from, but in truth, I don't really know where to start myself.
Any help is greatly appreciated.

The safari dev docs are your friend:
http://developer.apple.com/library/ios/#documentation/AppleApplications/Reference/SafariWebContent/HandlingEvents/HandlingEvents.html
Checkout the the touch move section for moving a div, for your case you want to set conditionals for if the user goes outside the bounds of your outer div, and disable scrolling using overflow hidden.

Twitter button causes text-align:center not to work

I'm trying to add a twitter "follow" button to the footer on my site, but it is causing numerous problems with the display of the footer.
If you take a look at this fiddle, you can see the issues. I've added testing controls to make it easier to demonstrate, but basically, I want to stop the following things from happening when the button is added:
Extra padding at the top
Everything being moved to the left (losing text-align:center)
The button not being vertically aligned with the text to the left of it.
Please can someone advise on how to achieve this?

The Twitter button gets styled through javascript to a width of 300px, only thing getting around that is to wrap it up with a span or a div and put it on a width of 60px; Because 300px pushes you menu to the side. Losing your text align center.
Also you might want to wrap your links in a unordered list element so you have more control over the whole group and it becomes more semantic.
My solution

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.

Make a div fall off the page

So I have been playing with jQuery for a good time now and I'm trying to get an effect to work properly. I have a main square div in the middle of the page and when someone clicks a link I want the box to look like its falling off the page and disappear, revealing a new page behind it. I'v been playing with the easing plugin but I can seem to get what I want to work. Basically I have the div's top margin or just top distance increased to a large number. However, this just makes the div fall but it also expands my page and its just much lower on the page. I basically want the div to fall out of site and not change the dimensions of the site. Anyone know how to do that?
Thanks!

To prevent your page from redimensionning upon clicking on your link, add overflow:hidden to your div container 's css properties.
also, make sure you hide the div when the animation ends.
$('a').click(function(){
$('#thediv').parent().css('overflow','hidden');
$('#thediv').animate({'top': '+=500px', opacity: 0},function(){
$(this).hide();
});
});
