Main Page Across to Opening Page

Just started and I love this theme and have just worked out a fair bit of it. However for some reason i cant get my “main” page that i have constructed to be on the opening main page eg like the demo. I can t move the “blog” post out of the way, so my page goes to the side?? Sorry for my naivety i just need help on this final part. Thankyou

I’m not sure I understand. Have you set your static page from Customize > Static page? And have you assigned the Front Page template to the page you want to use as static?

Thank you so much. Appreciate your help on this. All fixed.
