Thank you Basara, I'll try it. have to find where to put it first. That's my main problem. I can insert certain things through the html blocks, but other codes I need to get into the root files. Finding the right ones is the issue. I use the page source panel in win. but it's a bit confusing trying to find the exact script page.
LOL, it's not like the days when working in wordpress with "type this using this code and get Hello World" in html and some PHP, then you made a simple web page.
Ok, so I went into storefront/view/default/stylesheet for bootstrap5 theme and went into style css tried a few test colors in a few areas and nothing changed.
If I go to public/extensions/bootstrap5/storefront/view/bootstrap5/css/style.css same issue.
This is the problem I have, so many areas and not knowing the right one to get into to make changes, or do all these areas lead to the same style.css?
