When i put into coding it says it's wrong. What am i doing wrong?
You learned in html basic that the doctype declaration is: <!DOCTYPE html>
This exercise on purpose only mentions doctype so you either have to remember the correct tag/look at documentation/earlier exercise.
The declaration for an HTML5 document looks like this:
I think you're missing the html part in there :)
Edit: And Stetim94 beat me to it :)
is it case sensitive?
see this stackoverflow question. In the exercise on codecademy however, SCT (submission correctness test) could be programmed to only accepted uppercase DOCTYPE
If you want to better understand what <!DOCTYPE html>means,
<!DOCTYPE html> tells the browser that the language is HTML.
P.S. I am very sorry if I replied 6 months late...
