Twenty Twelve adding code for line space between paragraphs

here’s a link to the style sheet

That URL is not to the twentytweleve stylesheet

/wp-content/themes/twentytwelve/style.css would be the stylesheet.

Okay. In any event, can you see the page, and see what I need to do, or do I need to do something more here first..

We can’t see your site without a link, no.

okay, I think this is what you mean. I just tried it and it works.. so

Do not make changes to the twenty twelve theme files. You must use a child theme or custom CSS.

Some or all of the problems on your page is from copying from Word – it adds all kinds of crappy non-compliant code to your site – and it’s screwing up the CSS that’s already in the theme.

See this:

p.MsoBodyText3, li.MsoBodyText3, div.MsoBodyText3 {
    color: #666699;
    font-family: Sathu;
    font-size: 11pt;
    margin: 0 0 0.0001pt;
    text-align: justify;
}

Are you saying I should be typing it in fresh, then?

Absolutely – or use a plain text editor. Word really isn’t meant for websites and can cause major problems – much worse than messing up formatting.

Also, I do have a Child Theme. I’m confused. I seem to have to change the parent theme too. I made one change so far, so that the image I have only appears on the first page. But if I didn’t have it in the parent, then it didn’t work. So, I thought the child was working more as a back up, so I had that when I updated. Is this not true?

If you need more “control” in the visual editor, check out this plugin:

You are not currently using a child theme – the child theme has to be activated to be using it. The child theme is not a backup – and you should not be making changes to the parent theme – those will all be erased when WP is updated.

Are you saying I should always be in the child theme, then? And so, I need to upload the background image, etc., since I’ll be keeping it in the child, since that’s where any changes will be?

Also: even if I do type the article in fresh, it seems others here have a problem with having line spaces between paragraphs. Do you know if I will also have that problem? If so, what change do I need to make to the style.css [in the child] so that I always have a line space?

Yes.

Paragraphs in twentytwelve HAVE space – I do not see any problems with it, but if you want to make that bigger you can – in the child theme in style.css file add this:

.entry-content p, .entry-summary p, .comment-content p, .mu_register p {
    margin: 0 0 1.71429rem;
}

and change that number to something bigger.

Where do you recommend I place that?

Also: do you recommend I import [through my website host] the entire Twenty Twelve style.css?.. since right now there’s just a line in the child that refers to importing it. And it means I have to keep moving code over bit by bit if I don’t do that. But, would that be too large a thing to move that way? (I’m hoping I don’t have to figure out the whole FTP thing now) (sigh)

Do not put anything EXCEPT changes in the child theme style.css file. You will make a MUCH bigger mess for yourself if you copy the whole file. The whole parent file IS being imported already – if you copy it too, you duplicate code and make it much harder to keep track of what you have changed.

You need to put that code just below the @import line – do you have other CSS there already (hope not) – but you need to activate the child theme first.
