I didn't find every thing in html course.

Question

theres a new tag i saw today . it was marquee tag. so i am saying that way i didn't get in my html course.

Answer 1

marquee is an obsolete tag, it's no longer supported by the browsers. It may work on some but it's just a matter of time until it's no longer working on any of them.
Hope I helped! :)

Answer 2

Yes there are many obsolete tags like <center> and <font> just Google "obsolete html tags" if you want to learn more about them, but don't use them, because you never know when they will stop working. Some of them are broken and no longer work on newer browsers anyway.

Answer 3

like marquee is theres more tag that i didn't know.
