On your website, the program uses the style sheet associated with a web page’s layout to render the content you enter in the HTML editor. Because the part on which you enter the HTML content may be shared across multiple web pages with different style sheets, you may need to edit the content as necessary to improve its readability with a specific style sheet. When you use the HTML editor in the normal view, you can view the content as it appears with different style sheets applied.
Note: Other styles, such as those applied to the containers of the part, may affect how the content appears on the web page. To see how the HTML content ultimately appears on a specific web page, we recommend you use Pages & templates.
