Using Third Party Themes
Fusion is designed to be compatible with themes that adhere to WordPress' theme development standards. It is possible that some elements may require some CSS updates depending on the way the theme is built.
When using a third party theme you may need to update some settings on the Settings > Fusion page. If your theme does not include Bootstrap, you will need to turn on “Enable Bootstrap”. You may also need to turn on “Use Fluid Grid” so that Fusion’s content is sized to fit within the theme’s post content area.
