How do you code a blue background and change font size?

Hi, I'm coding using FreeBASIC and I need to know how to code a plain blue background.

Also, how do you change the font size of text?



Help would be greatly appreciated! :) ThanksHow do you code a blue background and change font size?
For the whole page:



body {

background: #0000ff;

font-family: arial, 'times new roman';

font-size: 1em;

color: #f0f;

}



I'm assuming you know how to use the CSS. Change #0000ff; to shade of blue you want. Change color: #f00; to contrasting color of text you want. Style rest to tastes.
