font size in paragraphs

I would like to increase the font size of the paragraph copy throughout the theme. I have found several other posts asking the same question. When I apply the CSS code supplied, it appears to change the size but then when I go to live view, the text size reverts to original size? Can you help with this? I have an under construction page up so you can not see the site live.

Hi there

Hope you are having a good day and thank you for your question :slight_smile:
