Hej, på chimpansernas tid var jag en apa...
The MARQUEE and BLINK were not officially "deprecated" (so cannot be marked as such) from the W3C TR because they were proprietary nonsense...
However the HTML5 non-normative document will mention them (and it’s not really a technology I would teach a newbie) and certainly not until they understood HTML 4.01, and were equipped to evaluate whether it were even a sensible option.
Though I do agree that SP Reference would have been better served; if it mentioned they were M$ and NS PROPRIETARY elements on those single pages too. Albeit it does briefly have: http://reference.sitepoint.com/html/...ts-proprietary. Personally I just use the official W3C TR myself as a reference but it's dry reading.
Aside one the SP Books on the Subject of HTML5 also fails to get this simple fact right with regards to EMBED, it wrongly mentions it being 'deprecated' from XHTML.
W3Cschools is pretty much sloppy affair regarding accuracy even though it seems fairly palatable with ease of reading.
You also need to grow a beard (Jag har ett stort skägg), meditate breath code and pray to the gods occasionally.
Those two Swedish instances in this thread are about the only Swedish phrases I know the latter being to impress the women. ;-)
