Again, I can't do a pull request because of my edits but in the SASS and SCSS and possibly some other flavours border-radius has been used where it should be rounded.
Namely any use of border-radius that has a single value in the brackets.
I believe you are looking in the Compass versions, in which +rounded is not necessary because +border-radius already exists in Compass. :)
I mean within the actual use of the mixins.
e.g. https://github.com/malarkey/320andup/blob/master/scss/_buttons.scss#L33 creates a top right 4px rounded corner where it should be on all corners.
This occurs on a few buttons, and also on the wells within _texture.scss.
Hrm, okay I will look into that. When I noticed Andy was calling out a particular corner rather than all corners, I opted for Compass'es mixins instead of Andy's so it'd be less repetitive code. Perhaps I accidentally ported some of that over to the non-Compass files. Will fix once I get a chance to look at it. Thanks!
Thats alright, thanks for doing all the porting in the first place.
