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

getting the form to pass validations smoothly

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

I'm proud of how well I integrated accessibility, with keyboard navigation, screen reader support, and responsive design. Next time, I'd focus on refining the visual design, exploring advanced validation patterns, and optimizing the success message. I'd also consider using a testing library to automate accessibility checks.

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

Are there any specific areas of your project you'd like help with, such as optimizing accessibility, improving validation logic, or enhancing the design with Tailwind CSS? Or maybe you're looking for feedback on performance, code organization, or handling state management more efficiently? Let me know!

    I'm afraid this has some quite serious accessibility problems caused mostly by the HTML in the form.

    • Inputs must always be labelled.
    • Inputs that collect personal data must have appropriate autocomplete attributes.
    • Required fields must use the required attribute.
    • The fieldsets under each input must be removed.
    • Error messages must be announced to screen readers and be programmatically linked to their input. The best way to do this is have an element wrapping each error that is always present in the DOM (not display none or visibility hidden etc). This needs a unique id and an aria-live attribute. Then the input needs aria-describedby pointing to that error wrapper ID. When an error is present you either unhide the inner contents of that error or dynamically populate it's inner content.
    • The query type must be correctly structured with a fieldset, legend and labelled inputs.

    This is also missing the success notification that's in the design, which will have its own accessibility requirements.

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.
