Increase or Change font size for content on pages or blogs.

I am using the blackbird theme. How do I increase the font size for any text added to pages or blog pages.

Thank you!!

 

Hello,

Paste the code given below in Custom CSS section
(Appearance -> Theme Options -> Styling Options -> Custom CSS) of your dashboard.

Code:

.page-content p {
font-size: 15px;
}
.post_content p {
font-size: 15px;
}

Thanks & Regards
