Hay ! you perfectly got the output. You just need to change the background color to view your output properly. Or simply increase the brightness!.
Did you try using a different browser?
I could be because you missed the closing brackets in /script.
@abhinab161098 Change the bgcolor attribute to white and the background color will be changed to white and you will be able to see the output.
@abhinab161098 change your ‘bgcolor’ to white or other any light color so that you can see your output correctly…Again you have not put the angular bracket at the end of script tag…
Change ur background color dood… It will be better
