Height set to 100% yet page not rendering properly - css

Question

Here's a link to my page: http://mobile.sheridanc.on.ca/~vecanski/
The problem that I am having is that height is set to 100% and yet i can still scroll down and see the light blue, even though there is nothing on the page except floating bubbles. Does anyone knows as to why I am able to scroll down? Also I have a gradient effect, here is the code:
background: #4094d1; /* Old browsers */
background: #4a97ce; /* Old browsers */
background: -moz-linear-gradient(top, #4a97ce 0%, #2687cc 22%, #1080cc 48%, #0c0c02 99%); /* FF3.6+ */
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#4a97ce), color-stop(22%,#2687cc), color-stop(48%,#1080cc), color-stop(99%,#0c0c02)); /* Chrome,Safari4+ */
background: -webkit-linear-gradient(top, #4a97ce 0%,#2687cc 22%,#1080cc 48%,#0c0c02 99%); /* Chrome10+,Safari5.1+ */
background: -o-linear-gradient(top, #4a97ce 0%,#2687cc 22%,#1080cc 48%,#0c0c02 99%); /* Opera 11.10+ */
background: -ms-linear-gradient(top, #4a97ce 0%,#2687cc 22%,#1080cc 48%,#0c0c02 99%); /* IE10+ */
background: linear-gradient(to bottom, #4a97ce 0%,#2687cc 22%,#1080cc 48%,#0c0c02 99%); /* W3C */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#4a97ce', endColorstr='#0c0c02',GradientType=0 ); /* IE6-9 */
What I don't understand is why does the gradient not go all the way, even if it is scrollable, why does it restart at the end of the page?
So 2 questions really:
How do I remove the scroll-able part of the page?
If I were to leave the scroll-able part of the page in, how do I force the gradient to extend to the very end and not restart?

Answer 1

you can figure out the problems like this by using browser inspect element
by the way, to fix this:
Remove #bubbles padding:100px 0
OR
Add overflow:hidden to the #container
