@ahmadabdolsaheb awesome! Thanks for implementing this and opening the pull request.

@mstellaluna would you be interested in QA'ing this? I think it's a good fit for you.

@mstellaluna I think that's one of the flex challenges - And not part of this PR?

[ahmaxed]

@mstellaluna Thanks for the QA and the feedback.

[mstellaluna]

@moT01 yea true hold on something not right....

[raisedadead]

Hi @mstellaluna this LGTM, can you hit the approve button and give this a merge, if all is OK?

[mstellaluna]

@raisedadead I had only one suggestion to this set of challenges
and it was for "Use grid-column to control spacing" specifically
my suggestion is to add a link to a visual aide as to what the lines are referring to since we don't see the grid lines in the preview

[mstellaluna]

otherwise there were no issues, was a great set of challenges

[mstellaluna]

@raisedadead i'll approve and merge and open a separate issue for the visual. it's something minor that shouldn't be holding this up at all..

[mstellaluna]

looks great

[QuincyLarson]

@ahmadabdolsaheb @moT01 well done my friends!

Thanks to @raisedadead and @mstellaluna for QA'ing this!
