I persevered with my OTBS application today, and got the style sheets incorporated into the application. So it now looks nice. Am using the same style sheets as the LearningWebApps screen casts did.
Unfortunately I have just hibernated my Virtual Machine and it takes to long to bring back up, so no pictures of the current version for now.
I was reading Workshops 5-8 this morning and got a little concerned that the flow of the workshops doesn't seem quite right. Workshops 1-4 have been about setting up the ruby environment and having it talk to MySQL. Workshop 3 had us build the model using the scaffold which effectively built a working model (minus the niceties). Workshop 5 then seems to go back to the beginning and holds your hand as you build the application. It seems like it would have been beneficial to read all 8 workshops before starting so that we didn't bumble our way through setting up an application.
