Hello There,
Thanks for sharing the screenshot. You may be able to do this layout in Cornerstone. You can follow these steps:
1.) Please section your section and add the background image.
2.) Please create a 1 column row which will hold the headline element.
3.) Create another row and this time, select two columns. Please enable marginless columns in the row settings.
4.) For each columns, please add some padding to have some spaces around and between your columns. And please do not forget to set the alignment to center.
5.) Add your desired elements for each respective columns.
Hope this helps.
