Thanks @Finn245

Could you resolve the merge conflict please? While doing this, could you also extend the link text for your added video to include"CSS positioning from"? So the link text should read "CSS positioning from Slaying the Dragon". That would make it sufficiently descriptive and accessible.

Looks like there's still the merge conflict to resolve.
I see you tried to resolve it by fetching and merging origin/main, your remote fork, except your remote fork is out of sync with upstream main (TOP's repo).

You can either sync your remote fork with upstream on GH, then redo the fetch and merge resolution to origin main, or you can skip the first step by just fetching from upstream main and merging upstream/main instead (i.e. syncing your local fork directly with TOP's repo).

Almost there! Just need the below quick change as well as removing the trailing space on line 72, and the extra blank lines at the end of the file.
Our lesson files need to end with only a single blank line, but it looks like there are 3 blank lines instead.

Oh okay so i have to remove the trailing space in line 72 and remove the last line which is the 75 so we keep only 1 blank line(74 one)?

Yep. Either remove the space on line 72 (it's not blank, it's a line with just a space in it), or remove that line altogether (we don't need it anyway). Then files must end with only a single blank line, so delete any extra blank lines at the end of the file.
