Datamaps hover pop up

I'm using datamaps to display the countries of the world, but have the graph centered. When I hover over a country, the pop up appears all the way to the left, accurate to where the country would be if I didn't center it. I believe the issue is the css:
#map {
margin: 0px auto;
width: 700px;
}
But I don't know how to center it in a different way.
Is there any way to change where the pop up appears? Thanks in advance!
(I tried to add a code snippet, but it was getting an error for some reason.)

Changing the position to be relative works. As Eric Hoose's example shows, the <div> is relative, so the hover still works.
#map {
margin: 0px auto;
width: 700px;
position: relative;
}

The hoverover popup is attached to the dom via the datamaps-hoverover class. By default, d3 sets this position: absolute, with top and left attributes being set dynamically based on where the mouse is. Since the position is absolute, it shouldn't matter that you have the map centered.
For example, I added your css (while renaming the id to match the example):
#container1 {
margin: 0px auto;
width: 700px;
}
to the jsbin that datamaps uses as an example here.
As you can see, the popup is still in the correct spot even though the map is centered.

CSS overflow: auto by 'touching' bottom div

I want to make a div scrollable when its touching the bottom div.
I tried this:
margin-bottom:30px;
position: relative;
overflow: auto;
but it didn't work.
I created a fiddle tho show you my problem:
https://jsfiddle.net/wp3wvuj2/1/
For explanation: When you type in in a input field a new field is added to the div (This function is simplified). I want that before the input fields touch the element below (the START-div) it gets scrollable (overflow: auto).
Somebody have an idea?
Edit:
I noticed that nobody understands my problem.
I'll try to explain it better:
I have list where players add their names. The list has minimum 4 players maximum ∞.
The start buttonis placed at the bottom. The problem is in a iphone 5 it looks like this:
And now if i would add another player input field it would Overlap with the START-Button. Thats the reason why I want it scrollable now. I already get that work with a fixed height, but i want it responsive!
Because on a iPad for example it looks like this:
And I want prevent an overlap with the start button like this:
So it should get scrollable before it overlaps (dependent on the display size).

Updated JS fiddle, try this, i have updated CSS part in your code
https://jsfiddle.net/wp3wvuj2/2/
.main_input {
width: 209px;
top: 70px;
margin: auto;
margin-bottom:30px;
/* position: relative */
overflow: auto;
height:216px; //Give some height always to apply overflow auto
}
.main_start {
width: 100%;
margin: auto;
/* position: absolute */ //Not required
bottom: 20px;
font-family: Pamela;
font-size: 36px;
text-align: center;
}

I've only changed the styles on class main-input
.main_input {
width: 226px;
height: 234px;
top: 70px;
margin: auto;
margin-bottom:30px;
position: relative;
overflow-y: auto;
}
EDIT:
Please note for this solution to be able to work, I needed to remove the Top and Bottom positions of some elements as they were breaking the layout. Please use Margins or Paddings to get that styling you desire.
This now works to scroll once the space runs out on the page.

Fixed div disappearing on scroll left Css

I looked at many answers here on SO but none worked for me.
Below are the posts I have looked before posting this question.
jquery fixed div on scroll-down
jquery fixed div on scroll, smooth movement
jquery fixed div on scroll, bottom boundary
How to manage css left property for fixed div
fixed div position on scroll is not working in all conditions
Absolute DIV inside a relative DIV inside a fixed Div disappears on scroll
Sticking a fixed div on scrolling down
For this purpose I have created a fiddle that shows my problem :
jsfiddle demo here
My problem there is the login span disappearing on zooming (I can't see it on scroll right)
#fixedContainer
{
background-color: #ddd;
position: fixed;
width: 500px;
height: 100px;
top: 0px;
margin-left: 20px;
}
.login
{
float: right;
}
I would prefer a CSS solution but am OK with a Javascript solution too.

Add these css attributes to your #fixedContainer selector:
overflow-x: auto;
max-width: 100%;

How can I place a link at the bottom of the viewport on first page load?

I'm trying to achieve an effect similar to the one seen here on Dropbox's landing page. Notice that there's a link at the bottom of your browser viewport ('learn more'). This is always at the bottom of the page on first load. However, it's not fixed to the bottom of the window as you can scroll past it.
Any idea how to achieve this? A CSS or jquery solution is fine.

It's a link within a div which has the following CSS (the div's):
position: absolute;
bottom: 50px;
left: 0;
width: 100%;
text-align: center;
cursor: pointer;
The important parts there are position:absolute and bottom:50px

Css float:right 100% Height, image align bottom

Im using a float: right on my website. I want to make that div 100% of the window height minus a 10px margin. I want the height to resize with the page.
I also want the image in it to sit at the bottom of the 'container' minus 10px padding.
I've tried adjusting everything, and am sure its something in the code conflicting but i just can't work it out.
Thanks for any suggestions in advance.

I suggest you use absolute positioning instead of floating for this, you can make elements expand by setting for example top and bottom at the same time.
Absolute positioning could work for the image as well if you set its bottom to 10px (its offset parent will already be the right container, because any position other than the default static makes the element an offset parent).
Quick example:
/* this makes your body take up the whole screen */
html, body { height: 100%; }
/* the positioning magic */
#right { width: 100px; position: absolute;top: 10px; bottom: 10px; right: 20px; }
jsFiddle Demo
​UPDATE: and an updated jsFiddle to show an example on putting another element in the container and positioning it to the bottom.
#image { position: absolute; bottom: 10px; left: 20px; }
