Use the following guidelines for text in fixed-layout books:
“Wavy” and other strongly-formatted text can be created using SVG text paths. Apple recommends that SVG should be used sparingly.
Note: SVG text selection is best when each letter is in its own <tspan>.
When using absolute positioning to place text in fixed-layout books, Apple recommends positioning the text at the sentence or paragraph levels; not at the word level. Positioning at the word level results in a poor user experience when selecting text and using search.
