Phantom Bottom Border Around Script - javascript

I am trying to find the source of a bottom border in my small personal website. I have a processing sketch in the background that I'm trying to stretch to the full size of the page. I also want my body element to render from top to bottom.
This is my issue:
I made the html background a garish yellow for high-visibility.
I have a div holding the sketch for absolute positioning with no margin and no padding.
Inspect element doesn't reveal where the space is coming from and I've tested it in FF and in Safari.
Here is the page: My Personal Page (http://asperw.me)
My research on this question turns up results where top margins had collapsed or there was a random top padding but I'm fairly sure neither of those my culprit.
Thank you.
Edit: I should mention that I don't think the problem is with the sketch as the height of it is equal to the height of the body element. You can also right-click and view image and it doesn't have the bottom border there.

Full Width Header Shifts as Scroll Bar Appears

I have a strange question -- my apologies if it is a silly one. Please note the code it too large to reproduce in a snippit so I am posting the link here.
The page I am building is a small intranet page with a full width header. When the user clicks on the button beside the submit button, a div from the top opens and pushes the content down. My problem is in my code editor there is no scroll bar on the page, so when the div opens it pops the entire page slightly over to the left to compensate for the scroll bar.
On codepen, I've pasted the shell of the site, but because a scroll bar is included in its code area, the problem cannot be reperoduced exaclty.
Is there any way I can compensate for the lack of scroll bar in my code? Perhaps force one to be there?
Any help would be grand.
You can force a vertical scrollbar by adding the following CSS rule to the body:
overflow-y: scroll;
EDIT: I misunderstood your question.
Have the whole moving element absolute positioned and wrap it around a container. The scrollbar will appear on the wrapping container, not on the element itself. And because it will be with position absolute there won't be any change of position once the scrollbar appears.

Detect HTML and CSS for a DIV and change to make it scroll with a sibling DIV

I am building a Google Chrome extension and one of the features it does is generate a full page length screenshot by snapping a screenshot image of the viewport then scrolling down the page and repeating the process until it has an image of the whole page length and stitches them together as 1 image using HTML5 Canvas.
Page elements that are position: fixed get changed to position: absolute so that it doesn't show the fixed element in each viewport image in the final image repeated over and over!
Now I have a page for example that gives a new challenge.
https://docs.hhvm.com/hhvm/installation/linux#ubuntu-15.10-wily-werewolf
Based on the image below...
1) the top header bar is fixed so it changes to position: absolute
2) the main page right scrollbar scrolls the main right content panel down the page.
3) the left sidebar has a separate scrollbar for it's DIV.
When my extension makes a screenshot on this page, it ends up repeating the left sidebar contents over and over all the way down the page since the right scrollbar goes much furthor down the page.
I think the solution is to somehow detect and make the left sidebar in these cases be positioned so that it does not have a scrollbar and instead will show all the left sidebar content as the right content DIV is scrolled down.
I am just not sure about how to do that left sidebar part at the moment, any suggestions? I would need to detect this situation on other pages automatically as well!
CSS overflow is what you are looking for, I guess.
Try setting overflow: visible to that sidebar. Now the "auto" value is likely to stand there.
What about detecting... You can check the scrollHeight of the element and get its height, for instance sidebar.scrollHeight > sidebar.offsetHeight. If it's true, it means it is scrollable.

hr behind div in mobile

I have code working on all desktop brosers, but in mobile it has a bug.
The lines are hr elements and the square in the middle is a div. The div has position: relative and fixed width and height. I don't use z order.
On mobile all I can do for now is display the background of the div element with certain color, and I can see its indeed occupying the space. I also see in this case, where I use background color, that the hr appears behind it.
Additional information which could be useful: The div in the middle is part of an horizontal ul element, which contains list images with items and also text. Also called content slider ;)
When I initialize the slider with some image slides in it, on mobile, the layout is always displayed correctly. Also when I'm viewing only content slides. But when I put only content slides from the beginning, this error appears.
I don't know what it is... tried getting this behaviour with desktop browser, to find the cause, but didn't success. I don't know why the hr goes there. There's no relation with the content in the slide. The position where the hr appears is somewhere in the middle, between the text...
Thanks in advance.
Without seeing any of your code, a "best guess" based on past experience is:
It looks like you might have floated content inside of your slider, and the slider itself is not "cleared".
If you have any floated content inside of the slider, make sure the outer slider div is cleared.

Increasing width of element to page width on fixed-width page

I have a site that is a fixed width, within the content area I am displaying a log viewer.
The log viewer is hard to read as it is confined by the fixed width of the site and the log lines are quite long.
What I want to do is above the log viewer have a button that says "Expand", when clicked the log viewer's width would grow to be just slightly less than the size of the viewport.
The rest of the site would still remaine fixed width but the log viewer would be as wide as the screen.
I've drawn an image of what I want to achieve here:
http://imgup.co.nz/3940
I have tried setting "position: absolute; left: 20px" (As well as setting the width) but this causes the footer of my site to move up to be under the log viewer (As the log viewer is no longer increasing the height of the content area).
I'm not sure what to do, it should all be css related I believe.
Any help would be much appreciated!
Try this: http://jsfiddle.net/h4C2p/
EDIT: Sorry, that won't work for different widths. Here is one that works:http://jsfiddle.net/h4C2p/1/
if you don't mind setting a height for the content area, set it for the parent of the element of wherever you show the log.
or, don't wrap everything in one tag. ie. have separate header, content, footer, that normally have the same width and are centered, but when you click expand, the content.. expands

Fade text out when scrolling

Basically what I have is a page with a background image and when I have content which is quite long and overflows. I want the text to be inside that image and it appears to fade out when scrolling at the end of the image and the top of the image. I do not want internal scrollbars. The background image itself is fixed and centered and I want the text to always remain inside there.
Is this possible? if this is not clear then I will try and explain myself further.
I have looked at options in Jquery and CSS fading but cannot find exactly what i want.
Any help is appreciated!
Thanks

I would suggest you plant an image overlay (white to transparent) at the top and bottom of the div, but that might not work because of your background...could we perhaps see the background you are using?
The two images Nexxeus says should be placed in a fixed position at the top and bottom of the browser. You shouldn't touch what the overflow does, since it will be hidden below the two images.
