When copying content from an outside source, always use the Paste as Plain Text function to strip outside formatting. This will ensure that the proper pre-defined font options are applied to the content.
Using additional font options is not recommended as it is best to streamline content font. It is best to only use the Style Tags option.
Resize and Crop Images prior to using imagery on the website to ensure the proper dimensions rather than resizing on the page.
Remember to Save after edits are made or edits may be lost. Once Saved, the changes will publish live.
