Make textbox smaller, so that it doesn't create space at the bottom (avoiding the scrollbar)

I wish to make the textbox on the bottom of my home page smaller (remove the space above and below the text), this is because i wish to avoid the appearance of the scrollbar. Is it possible to make a textbox smaller?
