+== Styling lines of a gloss
+
+Each of the aforementioned text parameters has a corresponding style parameter,
+formed by adding `_style` to its name: `header_text_style`, `source_text_style`,
+`transliteration_style`, `morphemes_style`, and `translation_style`. These parameters
+allow you to specify formatting that should be applied to each entire line of
+the gloss. This is particularly useful for the aligned gloss itself, since
+otherwise one would have to modify each content item in the list individually.
+
+In addition to these parameters, Typst’s usual content formatting can be applied
+to or within any given content block in the gloss. Formatting applied in this
+way will override any contradictory line-level formatting.
