Discussion:
Spelling error: The waypoint requirements say, "You should have three li elements on within your ol element." I think "within" is the better choice here.

Typo on the first test "your text field have the property of being required". Also, the second test passes even if the placeholder text field is empty.
Thanks for the report, the copy has been updated.

This isn't exactly a bug, but in the description for the challenge, there is an image that shows how bootstrap lays out elements on a page. This image is way too small to see or read any of the text in the image, and there doesn't seem to be a good way to get a larger version of the image.
Thanks, we've updated the copy to have the image link to the specific section of the bootstrap website!

One of the requirements are not fulfilled (Wrap your all of your checkboxes inside one div with the class "row".) even though the codes have fulfilled the requirement. Per checking my code 3 times, I know I have fulfilled the requirement. Kindly check and see if this is just an error on my part. Thank you.

That test has a typo, it should tell you to wrap your input field and button in the div (like it does in the instruction text), not the checkboxes. Also, if you wanna show your html, .
Alright! That worked! Thank you very much! :) Should I close this issue now? Newb in Github here.
The "bug" is still present so you can leave it open. If you want to fix it yourself, you can open a pull request. If you look it seems like an easy fix, and you can use the little pencil button at the top to do it all right from within GitHub.
I'm actually lost with Github. Tried opening a pull request but I really don't know where to go. I guess I ll study Github first?
Thanks for bringing this issue up. We've cleaned up the copy!
