It keeps track of pricing per item and total price. You can reset the whole list and modify items in the list. It uses the CSS Flex/Flexbox for positioning certain elements on the page. To modify an item's price, enter a price in the price field, check the checkbox to the right of the item (or items, can modify multiple items at the same time), then click the Modify Item Price button. All items checked off will have their price in the list updated. I should note that its only the list itself that'll get the price updated.

The server calculates what the total cost (before any tax for taxable items) of the list would be and sends that back along side the actual list itself for the client to display the list and total price. Users can reset the entire list + +- **Tech Achievement Two**: Users can modify the price of any item added to their grocery list ### Design/Evaluation Achievements - **Design Achievement 1**: +1. Heineman +2. He thought it was hard to tell when the list was resetting because of my sample item being similarly styled from a font perspective. He also said that it was unclear what the middle checkbox was and that I should add a label for it. +3. I was surprised with his raving about the total price calculation. That felt like such a basic feature. He liked the simplicity of my design which kinda surprised me also because I thought it was a little too simple in its current state. I was going for simplicity but I thought the current design is a little too simple. Most of ym styling was positioning, not actual design styling from the colors and other things +4. I added a label to identify what the middle checkbox does due to his feedback. I also would like to add more distinction between different elements based on his feedback. They all look too similar and some design distinctions could be beneficial. diff --git a/public/css/main.css b/public/css/main.css index 9f8412e0..cbe92885 100644 --- a/public/css/main.css +++ b/public/css/main.css @@ -14,12 +14,20 @@ h1{ justify-content: flex-start; padding-left:7rem } - +.groceryItem{ + font-weight: 300; +} +label{ + font-family: "Oswald", serif; +} #groceryList{ display: flex; flex-direction:column; list-style: none; } +#groceryList #modbox-label{ + padding-left: 1.5rem; +} #cartList{ display: flex; flex-direction:column; diff --git a/public/index.html b/public/index.html index 142c1f02..f6743779 100644 --- a/public/index.html +++ b/public/index.html @@ -19,6 +19,7 @@

Define a specific task for them to complete (ideally something short that takes <10 minutes), and then use the [think-aloud protocol](https://en.wikipedia.org/wiki/Think_aloud_protocol) to obtain feedback on your design (talk-aloud is also fine). Important considerations when designing your study: - -1. Make sure you start the study by clearly stating the task that you expect your user to accomplish. -2. You shouldn't provide any verbal instructions on how to use your interface / accomplish the task you give them. Make sure that your interface is clear enough that users can figure it out without any instruction, or provide text instructions from within the interface itself. -3. If users get stuck to the point where they give up, you can then provde instruction so that the study can continue, but make sure to discuss this in your README. You won't lose any points for this... all feedback is good feedback! - -You'll need to use sometype of collaborative software that will enable you both to see the test subject's screen and listen to their voice as they describe their thoughts, or conduct the studies in person. After completing each study, briefly (one to two sentences for each question) address the following in your README: - -1. Provide the last name of each student you conduct the evaluation with. -2. What problems did the user have with your design? -3. What comments did they make that surprised you? -4. What would you change about the interface based on their feedback? - -*You do not need to actually make changes based on their feedback*.
