Solution retrospective


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

I'm proud that I completed the entire project from HTML and CSS to JavaScript, including the discount logic and slider functionality. It really helped me solidify how to connect user input to dynamic UI updates. Next time, I'd like to improve the visual feedback of the slider.

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

One challenge was making sure the price updates correctly both when the slider moves and when the billing toggle is switched. At first, the price only updated on slider input. I fixed it by extracting the update logic into a separate function and calling it from both event listeners. Another tricky part was styling the slider itself, especially changing the fill color dynamically. That required a bit of research and some custom CSS with background gradients.

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

I’d love feedback on how I handled the JavaScript logic for the pricing plans. Are there cleaner or more scalable ways to structure the plan data and event handling? Also, if anyone has tips on making sliders more accessible or improving the slider UX visually, I’d really appreciate it.

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.
