 * Hi Frank,
 * Nice to meet you.
 * My website is pretty fast, but I believe it has an above the fold issue because
   I am getting a brief delay with a white flash before pages load.
 * When I select “inline and defer CSS” and paste the block of “above the fold CSS”
   in the input field (text area), am I changing my theme files? (I use Generatepress).
   One concern I have is whether I need to set up a child theme to preserve the 
   change I will be making and to avoid modifying the parent.
 * A second concern is I am unclear about how to modify one of Siteocity’s four 
   minified/unminified critical path and load combined CSS files for pasting into
   Autoptimize.
 * Thanks for the plug ins and your help,
 * Joe

 * AO does not make changes to the original CSS (or JS) [@jbalisto](https://wordpress.org/support/users/jbalisto/),
   if you disable CSS optimization (or AO entirely) the original CSS will be used
   again.
 * regarding Silelocity; you need the “minified critical CSS file”.
 * hope this helps!

 * It did help, thanks.
 * As I add and modify pages with my page builder and make other changes to the 
   website, will I need need to update the “minified critical CSS file” that I paste
   into the input field for inline and defer CSS?

 * if those changes impact the structure of the visible part of the page, yes.
 * example:
    * in the top part of your page (visible without scrolling) you change
   an image for another one, but at the same place with same dimensions -> not a
   structural change, no new CCSS needed * in the top part of your page (visible
   without scrolling) you add column with a CTA-button in your page builder -> structural
   change, new CCSS needed * in the middle of your page (not visible without scrolling)
   you remove an embedded video -> not in “above the fold”, so no new CCSS needed
 * hope this clarifies,
    frank
