Quick Tip: Don't double space after a period in WordPress!
So, we were all taught in English class that you should always type a period and then two spaces before starting your new sentence. Well, not in WordPress because apparently WordPress doesn't like it. I started noticing indentations on my page if the new sentence lined up to the left, and I have noticed it on many other websites on which I have left comments or feedback.
Just remember: One space after a period in WordPress.
