Specification: https://html.spec.whatwg.org/ Multipage: https://html.spec.whatwg.org/multipage/#attr-media-preload Complete: https://html.spec.whatwg.org/#attr-media-preload Referrer: Comment: The preload attribute is case-insensitive in all browsers Posted from: 212.116.72.179 User agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/44.0.2398.0 Safari/537.36 OPR/31.0.1876.0 (Edition developer)
All tested engines (Blink, Gecko, Presto, IE11 and WebKit) do case-insensitive matching of the preload attribute, so e.g. setting preload="NONE" will reflect it as "none" and presumably also behave like preload="none". This is a bit silly, but pretty harmless, so I suggest changing the spec instead of trying to change all the browsers.
"The preload attribute is an enumerated attribute." -> "... ASCII case-insensitive ..." https://html.spec.whatwg.org/multipage/infrastructure.html#enumerated-attribute
Oh... thanks!
