Change style of all children elements inside a form at the same time

[Mando1]

I have a form with fields that I called from a SharePoint list.

The list has almost 100 fields. I have to change the style of each one manually, one by one.

There should be an option when selecting the form to change the style (font, color, font size, input background and border, etc..) of all the children elements at the same time.

High five. I wish I could say "select all" and change the font or sizing just like almost anything other MS product.
