What are you most proud of, and what would you do differently next time?

https://github.com/LivexTwin/tip-calculator-app?tab=readme-ov-file#what-i-learned

What challenges did you encounter, and how did you overcome them?

This was my first time building any type of calculator app, so of course, it came with a lot of bumps and bruises. But online resources and a lot of guides helped me understand exactly what goes into building out the business logic of these things.

What specific areas of your project would you like help with?

How could I have been more creative? For example, should I include a smooth calculation animation to make the app feel even more intuitive? Feel free to leave any feedback.

    Good work on the visuals and interactions! The app is true to the design and works well on responsive screens.

    From an accessibility perspective, the use of radio buttons is a bit confusing for keyboard-only users, as there's a lack of focus indicators and it's not readily apparent that a selection needs to be made by using the arrow keys, as opposed to using the Tab key. Additionally, the selected radio isn't indicated as active if it's selected with the keyboard. I'd advocate for using a set of HTML buttons, but that's ultimately up to you.

    Good idea on leveraging the IMask library. It sure beats having to manually restrict the character inputs like I did!

How does the accessibility report work?

When a solution is submitted, we use axe-core to run an automated audit of your code.

This picks out common accessibility issues like not using semantic HTML and not having proper heading hierarchies, among others.

This automated audit is fairly surface level, so we encourage to you review the project and code in more detail with accessibility best practices in mind.

How does the CSS report work?

When a solution is submitted, we use stylelint to run an automated check on the CSS code.

We've added some of our own linting rules based on recommended best practices. These rules are prefixed with frontend-mentor/ which you'll see at the top of each issue in the report.

The report will audit all CSS, SCSS and Less files in your repository.

How does the HTML validation report work?

When a solution is submitted, we use html-validate to run an automated check on the HTML code.

The report picks out common HTML issues such as not using headings within section elements and incorrect nesting of elements, among others.

Note that the report can pick up “invalid” attributes, which some frameworks automatically add to the HTML. These attributes are crucial for how the frameworks function, although they’re technically not valid HTML. As such, some projects can show up with many HTML validation errors, which are benign and are a necessary part of the framework.

How does the JavaScript validation report work?

When a solution is submitted, we use eslint to run an automated check on the JavaScript code.

The report picks out common JavaScript issues such as not using semicolons and using var instead of let or const, among others.

The report will audit all JS and JSX files in your repository. We currently do not support Typescript or other frontend frameworks.
