How do I make sure the interactive animations, like the 'essence' and 'feel' cascades, work in my content?

Every section of content must include specific data arrays for interactive animations. Without these arrays, the animated features of the content will not work. A developer must ensure these arrays are present and correctly filled.

The rule

Every section of content must include specific data arrays for interactive animations.

Without these arrays, the animated features of the content will not work. A developer must ensure these arrays are present and correctly filled.

A developer must include `essence` and `feel_snippets` arrays in every section's JSON data. The `essence` array enables a per-panel animation. The `feel_snippets` array enables a per-slide animation. If these arrays are missing or empty, the animations will not play.

A developer creates a new chapter for a learning platform. The developer forgets to add the `essence` and `feel_snippets` arrays to the JSON. A student uses the chapter and sees no animations when clicking the special buttons. The buttons appear, but they do nothing.

Questions people ask

How can a developer handle overlapping parts in an interactive SVG chart without flicker?

Realistic diagrams often have parts that overlap. For example, a bicycle bell sits on a handlebar.

How should a developer build the user interface for new chapters?

The user interface for Chapter 1 is the master design. All other chapters must use this design.

How can a developer make sure an overlay pane does not change the page layout?

A developer must use `position: fixed` or `position: absolute` for an overlay pane. This makes the pane float above other content.

How can a developer ensure a user interface panel keeps a constant height and does not shift or 'dance'?

A developer must define a fixed total height for the main container. Every element inside this container needs a fixed slot.
