Solution retrospective


Hello everyone.

I had a really good time w/ this project but the complexity was the JavaScript rather than the design itself.

I also added the possibility to use only the keyboard.

  • Arrow (left & right) to switch the theme
  • Numbers from 1 to 9, Operations & "." Dot)
  • Backspace to undo the last action
  • "=" Equal Sign to get the result
  • Delete to clear the calculator

I also chose to use SSR for the theming because i was annoyed by the flashing screen on previous projects on load before having access to the theme settings in local storage.

You can find the logic in the README of the solution.

Feel free to share your thoughts on my code/design and thank you for your time.

Have a good day/night. Peace.

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 1st-party linked stylesheets, and styles within <style> tags.

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.
