Notice some of the labels and components are not completely visible in the design
window. This shouldn't be a concern since they will be displayed properly in the
rendered page.
Notice how now each error message matches the label of the appropriate

label corresponding to a component that failed validation, vertical alignment is
temporarily lost whenever there are validation errors.
