Grid width fix

Somehow, changes that had been approved in #1 (this commit: https://github.com/elliottwilliams/openmrs-contrib-id/commit/36a520b05a07199afbe6e329be9f84eef482f4ed#diff-6c781c5eed9a3adea33917c6f325ba99L21) have been lost in main.ejs, possible due to a merge. I'm fixing the issues I can find.

Thanks!
