Twenty Twelve – Text Not Displaying Correctly

Hi!

I’m having a problem and I don’t exactly know how to describe it, so bare with me.

My blog is: https://www.betsycrocker.com

When I’m creating a post (that contains both text and pictures) and then go to preview it, the text never looks like it does when I’m writing the post. Some things are linked, others are just spaced funny.

I am not doing anything other than inserting a picture and writing a few lines of text. I don’t understand. Is there another theme you recommmend? Is it something I’m doing?

If there is a way to include sceen shots so you can see exactly what I mean please let me know.

Any help is greatly appreciated because this is very frustrating. A post that should only take a few minutes is now taking 3x as long!

Thanks!
Ashley
