The fine folks at Muse are working hard on the behind-the-scenes coding and such, which still leaves an opportunity for us lower-level opportunists to bring you nice widgets to fill in the front-of-house gaps... like this one!
Muse has basic underlining, especially typical for hyperlinks -- but we designers HATE stock underlining, don't we? After all, it was Robin Williams (our beloved writer and designer, not our beloved funny guy) who taught many of us to bold and italicize when Macs first started becoming mainstream. (Remember the term "Desktop Publishing?)
To that end, here is a widget to expand the options for underlining, should the need arise. And the need will arise, because proper underlining in design (using rules and strokes, and not cheesy text attributes) is not a bad thing at all.
Hyperlinks and Short Text
For hyperlinks or short spans of text, create a Character Style, name it, and then enter that name in the widget's flyout panel. Play with the other settings in the widget to style your underline, and then preview away. All text to which you have applied your named Character Style will publish with the underlining style you created in the widget.
You may have seen some of the Cool Kid websites that feature hyperlinks with thick, 50% opacity strokes that are half-under, half-into the links themselves. Now you can have THIS, too, using the Opacity option for the color of the stroke.
Strokes Between Paragraphs
With the Underlining widget, you can also underline PARAGRAPHS. To insert a custom stroke or "rule" between paragraphs as a stylistic graphic element, create a Paragraph Style, name it, and then enter that name in the widget's flyout panel. Play with the other settings in the widget to style your underline, and then preview away. (You can also indicate how far between paragraphs you want the stroke to appear.) And it's a beautiful thing.
As explained above, text to which you have applied your named Paragraph Style will publish with the underlining style you created in the widget.
