Logos should be uploaded as SVG for optimal results.
Wherever possible, use H1 or H2 components for logos, and place the brand/site name in the text. The .logo class will automatically hide, the text and replace it with the logo image.
Use these background image classes for reusable theme imagery throughout the site.
Create combo classes with your background image classes and the .bg-image-fixed class to create the 'parallax' scroll effect on the containers.
