I'm having difficulty copying in a Blog Post clone and spacing my content

Hey there.

I’ve copied in a blog page clone in order to make my CMS and article reading experience better. However have two problems.

  1. I need to correctly space out the rich text, so that things don’t look too squashed. I just can’t find out how to do it in the styles tab. It needs to look like the second site on the video.

  2. The box on the right hand side needs to stay sticky and follow the reader when they move down the article. How does one do that?

Same thing with mobile optimisation. Looks awful.
