Conditional Formatting to hide contents of cell

[Marcy]

Can someone tell me how to write a formula for conditional fomatting that will change the formatting of the cell when a date IS entered into the cell and left alone when there is no cell entry

And, while I am at it..is there a way to hide this same contents of the cell (assuming a date has been entered into the cell that has the conditional formatting) from the formula bar

Thanks in advance

conditional formatting will do what I think you might be asking for:
