There are a couple of ways you can text align all of the contents of a passage:
1. Using Aligner markup.
This passage text is right-aligned.
So is this passage text.
2. Using a known Passage Tag combined with a CSS selector that targets it.
You can use this technique to conditionally style the contents of your story based on the which Passage Tags have been assigned to the current Passage being shown. In this example I will use a passage tag of right-align to mark which passages within the project should have their text aligned to the right.
a. Assign the relavent Passage(s) the right-align passage tag (letter case sensitive).
b. Add CSS like the following to your project's Story Stylesheet area.
(how) to make the text bold
You can use Style Markup to apply text styling.
''this text is bold''
... if you are also using Aligner markup to right-align that text the above would look as follows.
''this text is bold and right aligned''
