Theme is Twenty-Eleven. I want to customize the appearance of a text widget only, including its heading. Following WPress instructions for putting links into a widget, I set up a new page, wrote the widget text the way I wanted it to look in Visual mode, copied it in Text mode; then pasted the Text mode into the 'Experiment' widget. It worked fine. But I could not find a way to make the widget heading (title) bold - it would not accept the same code. Can I customize the heading of the widget?
I would also like to make the widgets wider if I can, in sidebar template view.
Also to be able to separate individual widgets with a straight line.
The blog I need help with is truedemocracynow.com.
