Buttons – Appear Too Far Left or Not at All

Thank you for finding my post. Please help.

The Problem: Buttons either appear to far to the left of text or not at all on my website: http://glutenfreeworks.com. The buttons look fine on the text editor. They do not appear on the published or previewed pages.

I would like them to appear in the normal manner, next to the text. They only appear normal on one page: (No idea why.)

I am using the Crazy Pills plugin. The plugin makes different buttons, callouts, etc. I deactivated the plugin, but buttons still do not appear. (It is reactivated.) The plugin worked fine until the buttons got screwy.

Buttons appear on my subfolder sites, so I believe it must be the style sheet on this theme http://glutenfreeworks.com.

*Example of normal buttons on subfolder site:

*Example where buttons appear too far to the left:

*Example where buttons do not appear at all:

Here is the code of the style.css page of http://glutenfreeworks.com:

——————————————-
Color Palette:
#FFFFE0 cream bkgd
#6E0300 brick logo font
#FFD925 gold logo font
#005500 dk green
#BEC786 lt green

[Excessive CSS moderated. Please just post a link to your site instead.]

I saw a similar forum topic on buttons, but had no idea where to add the code suggested and noticed the moderator ordered another person who asked a similar question on that thread to start their own topic.

I am unfamiliar with programming, so please provide baby steps. (Which page to change. Which code to change. Where to place the code. What not to do in order to avoid totally messing up the site.)

Thank you!
