Setting font sizes, either per element or overall

I am working on creating a form, but it appears the default font size is awfully small. I know in UD setting this was done through themes and child themes, but I have yet to be able to get this to work in PSU. I tried following the docs under Styles but the example given only seems to work with a card and simple text.

This works as expected:
New-UDStyle -Style ’
font-size: 96px;
’ -Content {
New-UDCard -Title ‘Test’ -Content {

However trying to apply this to a textbox. a select box, radiobutton, etc. the style seems to be ignored. I have tried both applying the style to the element itself and wrapping it in a card, still no joy. Just curious, with the latest version of PSU, the easiest way to apply formatting to either a single element or (better yet) an entire form?

Product: PowerShell Universal
Version: 1.5.8

I thought PU supported themes? You need to right click on the element you want to style and find the CSS name for it. You could then use UDHelmet to style as mentioned in one of my blogs

Which shows how I use udhelmet to style a custom component via CSS

Thanks, I will take a look.
