Style sheets create unique elements such as colors, font types and size, and spacing for your website. Style sheets, written in Cascading Style Sheets (CSS) format, are easier to use than other methods such as HTML. Unless you specify a custom style sheet, your website uses the default style sheets. You can create custom style sheets in Style sheets that override a default style. When you override elements in style sheets, we recommend you make changes only once to update the pages that use the style sheet. This saves time and helps eliminate mistakes when you update your website. You use style sheets when you create layouts in Layouts. In Layouts, you link a style sheet to the layout.
