Markdown support

Each Slidium presentation is a plain markdown text file. You can open regular markdown files having the .md extension. You can also use the .sld extension in order to open your files automatically with Slidium. Slidum Markdown converter is based on Multimarkdown . Most of it syntax and features can then be used in your presentations.

Meta data

Slidium uses metadata at two different levels: – At presentation level, before the first slide. This is where you can specify the author , the theme, …. – At slide level, before its contents, where you can inform layout, background, transition,…


Each slide (including the first one) starts by --- . It means that the --- separator cannot be used.


Theme as to be informed at the beginning of the presentation (before the first slide), using meta data. Example: Theme: Modern


Layouts are provided by the theme. It means that you have to inform first which theme you want to use. In order to specify the layout for a given slide, you need to define the following meta data at the beginning of the slide (before its contents) Layout: Steps


Layouts can have different areas calls parts.
  • The number of parts depends of the layout.
  • Parts are separated by °°° on a new line
  • Layouts can be dynamic. In that case they have a fixed number of parts (for instance an header and a footer). The remaining parts from your slides are then dynamically mapped to the dynamic parts of the layout (a variable number of columns for instance)
