RE: Now, that the code is gone, shouldn’t the outcome be as it was when I first asked you for help?
This is what I see when I look at the page. The font size looks like the size I would expect it to be.
I think I finally understand the issue you are having!!!
You are actually editing the actual CSS file for the theme. The file is very likely named
style.css. Is that correct?
If that is correct, you should not edit this file!
Here’s why… it is likely to be overwritten during a theme update. The theme very likely has a custom CSS area in its settings. Add your custom CSS to this settings area. Refer to your theme’s documentation/support channel if you can not find it. My best guess is that it is in the theme Customizer.
Why are you having trouble when editing this file… the browser does not download this file over and over. The browser will cache this file locally on your computer to speedup the page load. So, if you make a change to the file on the server — you will very likely not see the change because the browser is still loading the old locally cached version.
If you want to edit this file and see the changes. Open the page in Chrome, hit the F12 key and then click the Network tab. Add a checkmark to the “Disable cache” option. Now, on every page load, the files will be requested from the server instead of locally cached versions but only when the browser console is open by hitting the F12 key.
