Unfortunately, as of 3 October 2016, Dropbox says it will no longer allow HTML files loaded in a Web browser to be rendered. The files themselves remain safe in Dropbox, but Dropbox will presumably give those who click the links the options of downloading the file or adding it to their own Dropbox folder, just as happens with non-Web file types now.
You might think that you could just switch to Google Drive, which also provided this sort of service, but Google Drive also discontinued hosting of Web pages as of 31 August 2016.
