[x] The nav on the homepage is linking incorrectly, it is looking in the folder above as it has ../ which means look in the parent of this folder not the current folder. As all files are in the same folder they don't need this (see screenshots below, I have your content in a folder YC-3 which is where the about/contact etc. pages are looking but home is looking in the folder above this and not YC-3 - see links bottom left) please remove ../ on home nav.
[x] Expanded menu does not need the logo animated. only the right menu should slide in not the logo on left. this just stays where it is
[x] logo and menu button do not align, the menu button should sit in the middle of the logo so they appear aligned
[x] menu text is slightly lower than the icon - text always has extra pixels above (no idea why - I think it's a line-height issue) so you always need to account for this and set a few pixels less with top margin/padding
[x] Expanded menu doesn't match the location of the collapsed menu. the margin from top of page was adjusted, this also needs to be adjusted in the expanded version so they seem to replace each others position
[x] Expanded version menu button should not still be active/visible - it should work the same way as WildKat example where the menu button fades out the menu moved in (there is a slight delay). could you not just take the code/js direct from WK and style the menu to match design?
[ ] The movement on collapse is very jumpy, the menu moving up and button fade back in are very sudden - again see WK for example (video below) it also feels jump as it slides out, maybe slow it down a little
[x] Home - the social icons are not clickable for last two, I assume it's due to the menu button being in front. maybe a z-index issue or may be solved when menu button is hidden as mentioned above. (see video)
[x] buttons - some of the padding between buttons (both text and icon) should be built into the A href - this makes the whole button area larger and easier for the user to click, the buttons current area is very small and hard to click.
[x] on all pages that the name/logo appears this should click back to the homepage
