Default Typography text problems

Hi. Please do not penalise me, as I’m not trying to “bump” my posting for attention, let me rephrase the issue: I’m new to WP and in layman’s terms; a dumb blond (although I’m a brunette): My theme has typography support. I need to edit the text size on a single page and I’m altering the text size as follows= Customizing>Typography>Default Typography>Appearance>Font Size slider. As soon as I use the slider, all the other pages font size changes as well, which I do not need to change. Do I need to create a custom font control on the Google fonts screen, in the settings section> Custom CSS field section for each page, or is there a simpler method? If I need to add custom CSS codes for each page, please provide me with the css codes, and, if possible, a short “tutorial” how to edit the custom css fields, as I have no idea how to perform such. I’m also currently working “offline in WAMPserver.

Nobody??????
And I believed WP was the most favourite and used platform to compile a website. Reverting back to WebEasy. WP, thanx.

1. If you alter the Typography of a Typography enabled theme, that typography would propagate through the entire site based on the CSS class or id that you are using.

2. In order to edit text size on a single page, I would suggest building a custom template for that page and define your own CSS classes or ids to use and add them to your custom.css or style.css file as necessary.
