and have entered the code as suggested into my custom.css file. That seems to have set the font size to match the rest of my site. However, the field title font, on the registration, page is all Bold. How or where do I elliminate that?
We use Bootstrap 4 which does not set labels to bold. That'd be styling coming from your Joomla template doing that and you'll need to contact your template developer regarding changing it.
Finally the font, on the registration page, is showing as Segoe UI. I have no clue where the system is getting that font from. Any thoughts?
We use Bootstrap 4 so the base font applied is the same as it, which is the following.
Code:
font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, "Helvetica Neue", Arial, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol", "Noto Color Emoji";
If you want to change this then you need to override the font-family style on the cb_template CSS class.
