Summary: One of the core recommendations we are proposing is support for embedded CSS in the head. While support for inline CSS is probably better than nothing, it isn't a solid alternative for true, standards-based support. Therefore, because of our recommendation, our acid test does not include inline CSS. Gmail does not support CSS unless it is inline. Consequently not a single item from our list is supported, nor is anything else. But even if Gmail supported embedded styles in the head of a document, it strips all IDs and classes from the source. So we would like to see Google remedy both of these ailments concurrently.
