To structure HTML presentation slides, you use specific attributes like `data-slide` and `data-level` on regular, section, and title slides to define their formatting and hierarchy within the single-file presentation architecture.

The journey bar progression system works by reading `data-level` attributes on section slides to update a 4-level system (`Low`, `Medium`, `High`, `Pro`), visually tracking the user's progress through the presentation.

To renumber slides after adding or removing content, you must update the slide numbers and ensure any relevant navigation links are adjusted according to the specific renumbering rules to maintain the presentation flow.

HTML presentation navigation works through standard arrow key inputs, swipe gestures, and the `goToSlide` function, while a slide counter displays the current position within the total slide deck.

The slide formatting types in a single-file HTML presentation include regular slides, section slides, and title slides, each defined by specific HTML structures and `data-slide` attributes.

You need to update `data-level` attributes on section slides whenever you modify the content flow, ensuring the journey bar logic remains intact and accurately reflects the 4-level progression system.
