Adjustment of search form

Please tell me how to adjust the search form. I want to change the size of search form, the color of background, and the color and the font size of its title. I also noticed a small problem-- when it works on mobile OS, the title of search form would align left, and the search bar would align right. Could they both align at the same side? (right side) I love the idea of floating. Great work! Thanks a lot!! My blog: www.cameldoc.com Morris
