Highlight style with mixed attributes

[Zealous_work5E55]

I need to highlight text but I already have a character style applied as needed; strong.

It appears that ID will only allow one char style.

I am trying to avoid a Highlight and Highlight Strong scenerio.

I have blocks of text, some words bold, that need a highlight applied. I am using a heavy underline with negative offset for the highlight.

Search engines and YouTube offer the underline technique but not mixed attribute solution.

Only one character style can be applied to any single character. It's a (somewhat frustrating) basic element of InDesign is that you have to multiply your Character Styles by as many variations as you have — you can't apply both a Bold and an Italic; you have to create a specific BoldItalic style.

There may be some very slight exceptions to this but in general even GREP and Line Styles are either-or and won't combine.

Note that this does not exclude applying multiple spot formats — you can use the inbuilt formatting* to apply bold, italic and underline to one word, even on top of an applied style — but in the organized styles, it's one per character.

*Except that you should rightly shun this unmanaged, built-in formatting as stemming from a momentary insanity of the developers. Never use them, that is. This is not Word.
