help something is wrong with my code

Question

https://code.sololearn.com/W3adxN6960HW/?ref=app I copied from git hub cleaned it up not sure what is wrong I guess css

Answer 1

The javascript runs before the document loaded, therefore getElementById doesn't work. You should either use the window.onload function or place the whole script inside the body.

Answer 2

In sololearn, html, css and js are included by default, you don't have to worry about that. I already answered your question

Answer 3

thanks but I have been having that problem Not sure excatly how to link the javascript . I think in the body like in the solo learn lesson <script src="what do I write here?/ demo.js" i dont know

Answer 4

alright, idk what that(wind.onload) is but I will look it up thanks

Answer 5

got it fixed, turns out it was just syntax error, I did add windo.onload and setupevents. seems that my real lesson here is about debugging, asking for help, and teamwork
:p
we did it!!!!!!!!
thanks
also just for laughs, it dosent work when I comment out set up events and window.onload
