How to Use The CSS Snippets
The CSS snippets I gave are to be used a starting point. Most of them will need to be edited to meet your needs. The items you would edit are listed in bullet points for each one.
Add The CSS Classes to the Section
Open the Section settings.
In the Content tab, add your background image and switch “Use Parallax Effect” to “Yes.”
Go to the “Advanced” tab.
Open the “CSS ID & Classes” toggle
Add the CSS class for the effect you need in the “CSS Class” (You can add more than one separated by a space.)
Be sure to ad one space (do not use commas) and add the class above for whichever setting you want to adjust.
