Line Spacing

do you mean that there are empty lines seperating your paragraphs ?
if yes , you can edit posts using “text” not “visual” and delete the lines between paragraphs , then update and check ..

Thanks for responding.

I mean there are NOT empty lines between paragraphs like I’d like.

I’ve discovered I can insert a pair of <p> </p> commands around a paragraph and get it to space, but that’s a little unwieldy to do to every paragraph every time.

I am having similar problems. I did an internet search (that was not limited to the twenty fourteen theme) and found posts in other theme’s forums related to this topic so it does not seem uncommon. Most of the posts I found suggested that certain plugin are causing the problem and that it is best to deactivate them all and see if there is still an issue. Pasteing text in from Microsoft Word may also cause problems

Using the above method I quickly realized my problem was due to a plug in called WP-Edit

Hi Dr. Bob,
to set the global css for paragraph (<p> tag) line height, use the following in your style sheet. If you don’t have a child theme you are using, you can add the custom css plugin to make it easy to add this spacing globally with just a few clicks:

Here is simple custom css plugin link:

Here is the css to add that will fix your line height. You can change the 2.5 value to whatever you wish, and then also change the margin-bottom value (which may be needed to avoid too large of a space between each group of paragraphs…if you want a symmetrical look between lines and paragraphs) ??

p {
margin-bottom: 24px;
line-height: 2.5em;
}

Cheers!
