no separate CSS
cover the whole page or just an element
specify mask color and opacity
specify Z-index so you can show popups over the mask
show an hourglass cursor over the mask
removing the masking div on maksOff so a different one can be shown later
stretch mask when element resize

return the mask element so you can style it etc
