Change the CONTENT WIDTH setting to FULL if you would like the content to go full width across the screen.
You may need to change the CONTENT HORIZONTAL PADDING: or CONTENT VERTICAL PADDING: settings found in the Content Padding | Alignment area.
You might also need to change your VERTICAL SPACING of the section as found in the default General Properties area.
To quickly remove padding or spacing you can enable the FIT CONTENT (OVERRIDE) found in the Content Styling area.
This setting overrides general snippet settings to get the result, and if the result is unexpected, uncheck the option to revert, and apply settings to snippets individually using the STYLE MODAL.
