Formatting Issues W/ Bog.txt – Sidebar – Images- Comments Section

My sincere apologies if this is something that finding an answer for should have been a piece of cake to do. I’ve googled, I’ve looked on here and I’ve ‘trial and errored’ for a handful of hours to no avail.

That is where my blog is located at and it’s just a couple days old. I’ve been able to tweak all the little things I wanted to on my own save for a few seemingly impossible tasks. I’m using the blog.txt theme.

1) I am wondering how I can make the sidebar move even more over to the left (so that it more closely resembles the spacing for https://www.landonspeers.com)

2) In my first post seen here, the comment appears on the side and I’m not sure how to make all things comments related go left aligned at the very bottom of the post with some more space between it and the post itself.

3) My third question is how to insert my images so they don’t present themselves so that I don’t have images jumping out of left alignment as seen here

All of my issues come down to simple formatting/alignment problems but I’m at a loss for where to make the proper corrections. Any help would be greatly appreciated and much thanks for your time!
