11. Summary Style Guide1 of 2 General page layout  No browser scrolling is required for any pages. Any scrolling should be programmed on the page itself.  No minimize or maximize options are available Background color is Green  Green represents vegetables Navigation panel is on the left hand side  Navigation panel contains all navigational buttons and in the same size for all pages  Button background color - #FBEAA4  Button font color – #F68225  Font – Arial Narrow  Must contain buttons that link to every major component of the application  Button color changes when the user is on the component the button links to

12. Summary Style Guide2 of 2 Buttons to perform major tasks on homepage  have different colors  Top part of the button contains an image – use of image relating to the task helps associate the action with the button  Bottom part of the button contains a description  Both image and description are clickable  Font for description – Arial Narrow Header  Contains title of the task which is the same as the button name  Title color is in white  Font - Arial Back and Next control button on the footer  background color – #F68225  Button font color – #FBEAA4  Font – Arial Narrow Main content section  Has white background  Uses a border to group all related content

13. Visual Design – Icons/Symbols Checkbox  A checkbox is often used for selecting items, even for non-technical users  The icons clearly shows when an item is selected or not Color  All screen background color is “green” to evoke images of fresh produce which is associated with grocery store.  Color numbers are limited to green, peach, white and such matching neutral colors. User will be pushing cart and looking at the screen. Do not want to overwhelm users with too many color choices. Need to easily identify screen contents.  The two types of navigational buttons use the same color but reverse background color and font color. It indicates the difference on the function of the button without introducing too many new colors. Buttons size  Size of the buttons is the main way users interact (touch) to navigate, therefore they need to be extra big for easy manipulation. Fonts  Fonts are pretty big in general because the screen is small and users may not have very good eyesight. Bigger fonts make it easier to read.

15. Homepage Design Considerations Same background color as is used throughout the application for consistency Contains the same layout as the rest of the application Main content  Contains 3 big buttons for user to navigate to other pages. They show the user what main features are provided for the application  Uses a different background color to help group the main content from the navigation panel  Uses different color for each main feature to distinguish the differences Clear description on the big buttons  Provide clear descriptions on all the main features of the application. So user does not have to guess what the application does. Image driven  Images are used in addition to description to associate the use of the functions  Suitable for standalone application with small screen Navigation panel  Provides links to all other pages.  Contains some repetition of what the main buttons link to so the panel would be uniform among all pages. Company Logo  is on the top left corner so the customer knows this is a tool provided by the grocery store, but not from a particular store brand.
