Browser Info is used to test various browsers' specifications.
All values are in screen Pixels. And all are dynamic, changing as you
change the browser.
Screen Resolution is the total number of Pixels on the monitor's screen.
(Set by the Operating System)
Active Viewing Area is the Pixel area within the browser's
visual window at any given time. Using the browser's
borders to increase or decrease the size of the browser's window changes
Browser Position is the Pixel offset from the left edge of the
browser to the left edge of the screen. Normal it is the offset from the
top of the browser window to the top of the screen, although SOME browsers
report the offset from the top of browser's 'active viewing area' to the
top of the screen.
Current Mouse Position indicates the Pixel position at the very tip
cursor arrow. Pressing the left Mouse Button shows the mouse position in a
yellow popup window. This is useful when the slider bars move
to a position out of view of the Mouse Position values printed in the fixed
squares - like right now!!
Uses: Aside from the obvious, you can go to another web page, adjust
the browser sides or the mouse pointer to a point of interest on that page.
Then use the browser keys to come Back to this page (Use 'ALT- Left Arrow' on
most browsers to come back, or ALT - Right Arrow to return to the other
page). Now read the mouse position (or click the left button
to get the mouse position). You'll know the exact position of
the item on the other page!
