Using the latest version of Aspose.Words (11.10) I've come across an issue importing an html document where not all of the css styles are imported.
In the below HTML sample the text "Heading 1" should be coloured blue, however when importing into Aspose.Words the colour attribute of the style seems to be ignored and the text ends up being coloured black.
Thanks for your inquiry. Please note that Aspose.Words tries to mimic the same behavior as MS Word do. Upon processing HTML, some features of HTML might be lost. You can find a list of limitations upon HTML exporting/importing here:
