Hi, when I try to change the type size in my widgets in "style widgets," nothing happens. The titles will change, but the text won't. Using 3.41. thanks!

This is what I see written next to the widget content box in 3.5.3. This may explain what is happening for you.

The Widget Content Box is gone since Atahualpa 3.4. for better plugin compatibility. It was a propretiary Atahualpa feature that provided extra styling possibilites but didn't play well with all plugins because some of them rely heavily on widgets having the same structure as in the "Default" theme (which does not have this extra DIV inside each widget). Instead of "div.widget-container" the styles that you put here will be applied on "div.widget ul, div.textwidget". That will cover all text widgets and all widgets that consists of unordered lists, which should be the majority of all widgets. Otherwise look into the source code of a browser rendered page of your site to see which DIV or other HTML element wraps around the body content of the widget that was not covered by this, and add a CSS Insert such as: div.some-class { margin: 10px }.
