Solution retrospective


This has been my favorite challenge from Frontend Mentor so far. I learned how to read and use API docs with this one. Feedback or tips on how to make my code more efficient is much appreciated.

    Really nice job on your solution. Looking spot on with the design. Your sass and javascript is looking well structured. Nice job on using mixins for breakpoints and using css variables.

    A couple things that i noticed in your javascript:

    1. I don't think you need to declare lat and lng variable in the global scope. You only set it once in the function, and pass is on to other functions as arguments. No need to declare it global i think.
    2. I see one 'var' variable which you might wanna change into a const.

    Another thing i noticed here in the accessibility report is that the submit button is missing a text label for screen readers. You might wanna add a screenreader only text element or add an aria-label to fix that issue.

    I agree with you that it was a fun challenge to work on, had a great time working on it as well.

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.
