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

* [Style Sheets](https://servicenow-prod.fluidtopics.net/ZhYfGsZM6ac4vH9N1EnVqQ "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://servicenow-prod.fluidtopics.net/_9AfgM3_UD3v63K3dplUzQ "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://servicenow-prod.fluidtopics.net/LndED9by2mz2lgd2_~ZdlQ "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.

  Design themes are the convergence of structure and styling, making them a critical tool for creating a powerful user interface.
* **[Doctypes](https://servicenow-prod.fluidtopics.net/dUh~dYuU3qBSL7yRJyb4bg)**   
  The view_content html page template on which all CMS is based defaults to `doctype=html`.
* **[Format a frame](https://servicenow-prod.fluidtopics.net/LndED9by2mz2lgd2_~ZdlQ)**   
  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.
