I have to plot a function, let it be Sin[x] in (0-pg), then I have a 
peculiar abscissa, ex. x=1.234.
I'd like to overlap to a normal grid and frame a vertical line at this 
abscissa in same different style
(as dash or color or thickness, etc.) . How can I do it?
How can I have also this value explicit as a tick on the plot?
Then all this would be even better if I could have two background colors 
(or gray levels),
before and after the selected abscissa.

Many thanks in advance, Roberto
