Change Paragraph Spacing in CSS Not Working

Hi All,

I need help regarding this issue. I’m running a 4.2 WP site and I wanted to change the paragraph spacing so the posts would be easier to read. I’ve read some answers here and one of them I decided to try but didn’t work:

Put the ff. code in stylesheet.css

.post p {
	line-height: 1.5em;
	padding-bottom: 10px;
	}

Site name: http://traviscody.com

Right now I like how the paragraphs are automatically double spaced when I press enter in the Visual Editor but I wanted the gap between paragraphs to be smaller. Does it make sense? Please help. I don’t know much coding.

Thanks a lot!

Marie
