Adding CSS Styles
HTML5 code is for defining the meaning of your web page content. To define how your page looks — for example, the size of the text, the background colors, and the spacing around images — you need to use Cascading Style Sheets, or CSS. This chapter gives you the basics about defining CSS styles and assigning them to your HTML tags. Getting a solid foundation with CSS is important in HTML5 because many style features that were available in previous versions of HTML now must be done using CSS.
