Blog Post Issue

Is it possible to style the page that individual blog posts are displayed from? Maybe I’m missing something, but whatever layout I save on the page designated in the side-panel “Customize” reverts to a basic page with side-bar – even if I have specified no side-bar with the Edit Pages dialog.

My point is that my design does not use the side par, my layout is full- width, with a side column in the row design where I want it.

I’m using Polestar as more or less a boilerplate. I want to individual blog posts to be displayed on a page styled as the rest of the site.

Second question:

If I wanted to build a Theme template from scratch, is there documentation for what is necessary for SitOrigin widgets to function properly?

Thanks!
