PDF onebox instead of download, on uploaded files

Oneboxing applies to external PDF links, not direct uploads. For example, an external link: versus the same doc, but uploaded: fw4.pdf (173.5 KB)

以及：

Format rendering of links to (local) pdf files?

As far as I know oneboxing will only work on externally linked PDFs, not uploaded ones. With CSS you could do something like a.attachment[href$=".pdf"] { color: red; &:before { // The attachment icon is added using a pseudo-selector // so you'd need to edit its styles here } } This applies styles to links with the class attachment only if the href ends in .pdf
