Placeholder that intentionally throws when written to — CSS must be declared at the kslides{} or presentation{} level, not on individual slides. Present so invalid usage produces a clear error rather than silently compiling.

filename

open override var filename: String

See MarkdownSlide documentation.

hidden

var hidden: Boolean

When true, the slide is excluded from navigation and the slide counter.

var id: String

HTML id applied to the slide's <section>; blank omits the attribute.

private_markdownBlock

open override var private_markdownBlock: () -> String

Implementation detail — do not use.

private_slideId

val private_slideId: Int

style

var style: String

Inline CSS applied to the slide's <section>; blank omits the attribute.

uncounted

var uncounted: Boolean

When true, the slide is navigable but excluded from the slide counter.

Functions

content

fun content(markdownBlock: () -> String)

Supply inline Markdown content for this slide. See HorizontalMarkdownSlide.content for the filename-vs-inline tradeoff.

css

fun css(block: CssBuilder.() -> Unit)

Guard against declaring css {} inside a slide — CSS belongs on the kslides{} or presentation{} scope. Always throws IllegalArgumentException.

processSlide

fun processSlide(section: SECTION)

Apply this slide's id/style/visibility/auto-animate attributes plus the merged SlideConfig to the given <section> element. Called by the slide renderer and not typically invoked by user code.

slideConfig

fun slideConfig(block: SlideConfig.() -> Unit)

Configure per-slide reveal.js attributes (transitions, backgrounds, Markdown separators, etc.). Overrides values inherited from the global and presentation slideConfig{} blocks.
