Assign classes to the body tags of pages using a master page
Use the following example to assign different classes to the body tags of pages using a master page file.
PREREQUISITES: Create custom field for pages and name it BodyClass. For more information, see Create custom fields.
Template
EXAMPLE: For more information about the markup, see BodyClassMasterPage.Master in Sitefinity SDK: documentation-samples on GitHub.
In the code above, you add a CSS class, named bodyClass, that specifies the page background color.
Thus, when you enter a value bodyClass for the BodyClass custom field you created, the background color will be the one you specified in the template.
Code-behind
EXAMPLE: For more information about the code-behind, see BodyClassMasterPage.Master.cs in Sitefinity documentation-samples on GitHub.
After you implement the page template and code-behind, you register the files as a page template in Sitefinity backend. For more information, see Apply a template to a page.
For each page that uses the page template, in case you want to change the background color of the page, enter a value for the BodyClass field, for example, blue.
