The page style can be adjusted in several ways.
With an external style sheet, you can change the look of an entire website by changing just one file! When a browser reads a style sheet, it will format the HTML page according to the information in the style sheet.
To include a reference to the external style sheet file in the layout click the Import or Edit HTML button
Add a <link> element to the top of the page
Internal styles are defined within the <style> element, inside the top section of an HTML page. An internal style sheet may be used if one single HTML page has a unique style.
After selecting the row or cell, you’ll find the row styling settings in the Styles Manager Sidebar.
