This style Customizes the Gmail header line in two ways.
1) Remove the DIV in the middle TD that hides informational text for screen readers. When the window width is narrow (due to a too large sidebar width or too small window width) this TD distorts the page (see pictures).
2) This is for the paranoids among us. If you are sure that spammers are standing right behind you and are trying to make out your address then this is for you. This style crosses out your address using light gray color that can be temperedly re-displayed by selecting the text with the mouse (good if you log into more then one account and can’t remember where you at). The style holds a couple more commented alternatives that can be used instead.
a. Cross out the address using black color.
b. Hide the address by changing its color from black to white.
c. Make the address text faint and hard to spot form afar.
d. Completely remove the address.
