Assign a theme to a page
In SXA, you can style your pages using themes. Themes let you change the style of an existing site, for example, because of company branding changes or if you want a holiday edition, without interfering with the content. You can use Creative Exchange to export and import themes. If you do not select a theme, the default theme is assigned.
You can assign themes to pages in the Experience Editor or in the Content Editor. You can also assign themes to specific components. For more information, read Assign a theme to a component.
To assign a theme to a page:
In the Experience Editor, on the ribbon, on the Experience Accelerator tab, click Theme, and in the Select Theme dialog box, select the theme you want to use. Click OK to save your changes.
In the Content Editor, on your site, click Presentation, Page Designs, and in the Styling section, select the theme you want to use.
