Solution retrospective


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

My first frontend mentor JS challenge, implemented using JQuery and Bootstrap. This is my second take on JS library JQuery and Bootstrap language so far but my first time manipulating CSS properties using JQuery UI. I completed this challenge by incorporating numerous cases that I encountered while developing this app with the help of regex.

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

Bootstrap by default has background color property assigned to .btn classes which I had trouble changing the property in :active pseudo selector using JQuery UI. However with the help of mouseleave() function substituting background-color property in active selector using JQuery UI became possible.

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.
