Top property is not honored in table row

Is it possible to keep the top row moving like we move the first column in a table using jQuery?
The code I used to keep the first column moving during scroll is something like this.
$('#table-name').scroll(function () {
var _left = $(this).scrollLeft();
$('.firstTd').css('left', _left);
});
when I use the same technique to top property to a table row...through the CSS gets applied it is not honored by the browsers.
P.S: I used left property on td element and want to apply the same technique to a tr tag
Demo here: https://jsfiddle.net/8w4qac30/7/

EDIT
Oops, understood the question bad. I'll keep the info below, but actually my answer is this.
As trs are quite picky, the only thing I can think of is to select all the tds and move them, like you do with the first one, like this: https://jsfiddle.net/8w4qac30/9/
Old answer
left, top, right and bottom are positioning attributes, and for them to work you should set the position attribute too.
position attributes come in different flavors:
relative means to position the element relative to itself, so if you add, for example, left: 20px to a relative positioned element, it simply will shift its position 20 pixels to the left.
absolute means to position the element relative to the first parent that is also relative or absolute positioned.
fixed means to position the element relative to the browser window and will keep fixed during scrolls without additional code. I think that you should go this way.

I need help figuring out how to toggle an element once vertical height of window is scrolled

I'm trying to toggle a div from relative to fixed when I scroll down 200px using javascript. When I reach 200px from the top of the window, my div should toggle to fixed. And when I'm above that 200px from the top it should go back to relative. Does anyone have an idea on how to do this?

Something like:
$(window).on('scroll', function() {
$("#myDivID").css({
position: $(this).scrollTop()<200?'relative':'fixed',
top: $(this).scrollTop()<200?'200px':'0px'
});
});
You'll probably also have to reset the top position of the element.

I know there's at least a couple of plugins that do this. Can't remember the name of the one I saw last, but here's one I've written myself: http://code.google.com/p/sleekphp/source/browse/trunk/Sites/SleekBase/Modules/Base/JS/jQuery.fixedIfNeeded.js
You use it like so:
$('#my-element').fixedIfNeeded();
There's one optional argument that specifies if the element should stop being fixed before it reaches another element (like a footer for example):
$('#my-element').fixedIfNeeded('#footer');

How can I auto-scroll as content is added to a div?

I have a div of fixed dimensions into which some JavaScript functions will be placing text over time. When the amount of text exceeds the height of the box, a scrollbar appears thanks to overflow:scroll.
The new problem is that the view into the div stays at the same place as more content appears. What I mean to say is that it stays scrolled wherever it is as more content appears beneath, hidden unless you manually scroll down. I want to make it automatically scroll to the bottom as new content appears so that the user naturally sees what appeared most recently instead of what's oldest.
Ideas?

You can use scrollTop method after each text addition:
$("div").scrollTop($("div").children().height());
Use inner block to get the true height.

I found this approach to work for my needs:
var realHeight = $("#history")[0].scrollHeight;
$("#history").scrollTop(realHeight);
Do note this uses jquery.

URL hash page jump... fixed header overlapping

So here's the deal,
I have a fixed header/navbar, and when I jump to something via a #urlhash it overlaps it.
Now I could add a div that goes before the content and jump to that, but that would end up messing the whole style up.
So I'm wondering, is there a JavaScript/jQuery trick to add about 200px of padding after a jump?

You could add an absolute positioned empty ( ) div with top:-200px and jump to that. Just make sure the parent element is not statically positioned (relative should do the trick)

How about:
$(window).onload(function() {
if (document.location.hash)
$(window).scrollTop($(window).scrollTop() - 200);
});

Resizing a div to fill the browser

I have a page with many divs and style, with my div buried somewhere inside.
I am trying to have a button that automatically makes my div, that includes a video player, resize and capture the whole browser.
In order to do that I am trying to get the current position of the div and then position it relatively so that it'll get to the top-left corner so I could then use document.body.clientHeight/clientWidth.
Can't get this to work.
I tried the approach of moving my div to the first div and then resizing however this messes up the flash player.
Any ideas? any different approaches?
Thanks,
Guy

Use one of the lightbox clones that can handle DIVs. They usually copy the DIV in question into their own view DIV, which helps with positioning issues and you don't have to do anything to the buried div.
I find Multi-Faceted lightbox to be very easy for customizations:

but there are lots of others around as well.

Why relative?
You should rather use fixed instead of relative. Then set positon to 0,0 and width and height to 100%.
Simple js can do this.

On click, just set the div's style to 'fixed', and position 0,0. Like:
var theDiv = document.getElementById('yourDivsId');
theDiv.style.position = 'fixed';
theDiv.style.top = 0;
theDiv.style.left = 0;

This should do the trick:
<div style="position:absolute;top:0;left:0;width:100%;height:100%">
