This documentation is not using the current rendering mechanism and is probably outdated. The extension maintainer should switch to the new system. Details on how to use the rendering mechanism can be found here.
- Caveats reported by the developers of the Emogrifier class used in this extension:
- Even with styles inline, certain CSS properties are ignored by certain email clients. For more information, review information here and here.
- Emogrifier only supports CSS1 level selectors and a few CSS2 level selectors (but not all of them). It does not support pseudo selectors (Emogrifier works by converting CSS selectors to XPath selectors, and pseudo selectors cannot be converted accurately).
- Finally, Emogrifier parses your CSS selectors in order, meaning later selectors will override earlier selectors that apply to the same element. Ideally they would be applied in order of increasing precedence, but that's not supported yet.
