The CSS renders well for these browsers, though margins, font sizes, and form
element rendering are inconsistent. Table support is present, and basic HTML
elements render very well. The error message at the top has the most complicated
CSS, but it shows up perfectly! Overall, we are good! We can now plan the back end
for POTR.
Creating the Database and Code
Architecture for POTR
We have learned the basics of graphic design and layout for mobile web applications.
Now, we will build the back end for Pizza On The Run. We want to allow easy
ordering of pizzas from mobile devices. We don't need to make the back end much
different from what it would have been for a website, so we will quickly go through
the common parts and look at the differences in detail.
Classes for POTR
We need to retrieve menu data from the database and save order information. We
also need to provide user authentication.
