Content pages can be styled with CSS, just like any HTML website.  
Three elements control CSS styles:

* [Style Sheets](https://www.servicenow.com/docs/BFw9iLiSoIzPHCE5hgynGA "Styles sheets are standard Cascading Style Sheets (CSS) that define the look and feel of all elements within the interface.") are records containing CSS declarations.
* [Themes](https://www.servicenow.com/docs/8CeMyTff6QZa6syZwqlOFA "Design themes are the convergence of structure and styling, making them a critical tool for creating a powerful user interface.") are groups of style sheets that can be invoked together.
* [Frames](https://www.servicenow.com/docs/NyghGtetlBmxPTEUIUhGXA "Frames provide a way to manage decorative containers for content blocks and any other elements within the site. For example, one frame can be a container, made of div or span tags, that is styled with rounded corners.") are UI macros that define the outer border of individual content blocks as they appear on a content page. Frames work by calling on particular definitions in the style sheets.
