Hi Kym,
Thanks for reaching out and thank you for using Crio Pro WordPress theme and BoldGrid Post and Page Builder!
In order to remove the extra padding in your content area you should be able to hover over your main section and select the black section toggle that appears to bring up options. You can scroll down a bit and simply select the “Stretch Section” option to eliminate the extra white space.
You can also control the padding and margin of a section manually from the Advanced Controls option just below.
I hope this helps! Please let us know if you have any other questions for us.
