General Formatting

Feature Supported Comment See Also
Character Style Yes Character style is imported from either inline CSS (style) or embedded or linked CSS style sheet (class) on span elements.

Inline CSS (from style attribute) is imported as direct formatting on the text (stored in the Font of the Run node). An Embedded or Linked CSS style (through the class attribute) is imported as a Style and applied to the Run node in the document. This formatting can be accessed using the Run.Font.Style property. A linked CSS sheet can also be downloaded from an external address on the internet.

When there is conflicting formatting on inline and embedded/external CSS, as with CSS the formatting from inline styles are taken first, then the embedded formatting and finally the external formatting.

Styles are imported from embedded or external style sheets. If there is no linked style sheet of either of these kinds then the document is imported with no styles (apart from default Normal style). To make sure styles are imported use a CSS style sheet of any kind. There is a load option to control whether embedded or external style sheets are read or skipped during HTML import. There is also an option to supply your own CSS style sheet instead.
