It is very easy to make a DIV tag which stays visible on a web page even if the page is scrolled up or down or left or right. There is an ASP.Net AJAX Toolkit control called "AlwaysVisible", but anyone can do it with simple HTML. All that is required is a position:fixed attribute in the div tag's style. To place the div tag in a particular position on the page, you can add attributes of top, left, right, and bottom. If you don't want to display your div tag in a corner, it is still easy to place it more towards the middle; it just takes a little extra coding. You would still use the top or bottom placement, but on your left field you would use a value of 50% instead of a number of pixels. If you don't want it displayed smack dab in the middle of the page which would likely hide text, you can use a negative number of pixels in the margin-left field to move it off to the left, or a positive number of pixels to move it off to the right.
