Disabling Layout Markup

Cascading Style Sheets:

Cascading Style Sheets (CSS) is a method used to add styles for features such as fonts, colors, or spacing to web documents. The use of CSS allows the composer to quickly and easily edit style features throughout the whole website. CSS can be disabled by selecting the DISABLE CSS option under the Style dropdown menu. If a checkmark is visible next to Disable CSS, then the page is shown without CSS use. If there is no checkmark, CSS is enabled. The example below shows a portion of a page with CSS styling enabled and the same page with CSS styling disabled.
