[Theme: Divi] How to change default paragraph size in blog posts

Divi from Elegant Themes? For future reference, you’d probably want to post your question at Elegant Theme’s help forum instead of here . . . because they’re the ones that have received your money.

I need to up the font size of the paragraph font for all posts, by changing the default font size.

Just the posts font size? Then this custom CSS should be sufficient:

Please not that you’ll need to change the numbers because I don’t know which font size you want.

.post {
font-size: 28px; /* post font size */
line-height: 120%; /* control top and bottom spacing between lines */
}

You can go to Appearance –> Divi Theme Options –> make sure you’re on the General tab –> scroll down until you see a Custom CSS box –> copy-paste the code I’ve provided above into that.

I’m pasted the code but it’s not working. Any suggestions please?
