This module is not working for me even though I am correct and have followed the video step by step
Possible defect…
The challenge tests do not work well on Safari, Edge, or Internet Explorer. The curriculum works best when using Chrome.
Let us know if you are still having trouble when using Chrome.
Thank you for helping make FCC better. Bugs can be reported as GitHub Issues. Whenever reporting a bug, please check first that there isn’t already an issue for it and provide as much detail as possible.
I have only used Chrome. and this is the only module that isn’t working.
It’s not just you.
It’s also not just this challenge, the height lesson is broken in the same way.
The moderators had me enter diagnostic queries into the console for the height lesson page at different zoom levels, thinking this might be the issue (i was using 67%, the error also occurs for me at smaller zooms, but does not occur for me at levels 75, 90, and 100).
though it seems it should work at any zoom level. (what level zoom were you using? does using 75, 90, or 100 get you around the error?)
for some reason the same error does not occur in firefox, which I used to run tests in these two lessons in order to complete the applied visual design curriculum. (this was before they had me testing zoom levels in Chrome; the error apparently does not occur in Firefox at any zoom level.)
I had similar issues on Google Chrome, I switched to Firefox and haven’t had too many issues (other than ones I make for myself) 
It did work when i went to firefox but not on Chrome. Will finish on Firefox from now on.
