christine123 on "Adjust line spacing within a specific post"

Hello!

How do you change the line spacing on a specific post? I've Googled and searched the forum on this topic. I know how to change the line spacing for all posts, but I can't figure out how to do it for one specific post.

I'm running WordPress 3.6.1. My web site is http://www.YoureSomethingElse.com. The post I want to decrease the line spacing is titled Lead the Way. I want to change the spacing from 25px to 5px.

Using Firebug, I have identified the line of code I want to change, which I believe is line 708. My problem is I don't know how to find that specific line of code in the Stylesheet editor.

I understand FTP is an option? I've never done FTP. I believe I can open the code somehow in a text editor, where the lines are numbered? And then FTP that updated file to my site? Seems if I could just find the line of code in the Stylesheet editor, that would be the simplest fix?

I've gone to Appearance --> Edit CSS and I've typed in this code:

.entry-content p {
    margin: 0 0 5px;
}

However that decreases all the line spacing in all the posts.

Many thanks!
