16.1 – Frontmatter

A frontmatter adds both a title section and metadata like authors and doi to your page.

The data is structured as YAML. Be careful to follow the rules for YAML formatting:

• keep the items properly intended
• strings containing colons must be surrounded by quotation marks

16.2 – Resizing Images

To resize images, use percentages, not absolute values. The CSS surrounding the markup cells ignores absolute values.

16.3 – Embedding Videos

Videos from the local filesystem currently do not work. Embeding videos from external sources like YouTube do work.
