Challenge: Progress Button

Published on by Andy Bell

Front-End Challenges Club - Challenge #004

We’re starting the new year with a beauty of a challenge. It might look straightforward from the outset, but as usual with a Front-End Challenges Club challenge, as we dig into the details, there’s a lot to consider.

The brief

Take the design assets and re-create this progress button with whatever front-end technology you want. Consider how state is managed and how the button works when there is no JavaScript available. If you do the legwork upfront, you’ll make the whole process a lot easier with this one.

Make sure that your challenge solution does the following as a minimum:

  • Uses semantic elements
  • Is usable with mouse, touch and keyboard
  • Presents an acceptable focus state (pro-tip: this should be additional to the hover state)
  • Uses aria roles effectively to announce state changes

Bonus points awarded if:

  • You create a solid state management system
  • Your solution is lightweight and performant
  • Your solution is fully accessible
  • You create appropriate transitions and/or animations between states

Assets

I’ve used Figma to design this challenge and you can run it with a completely free account!

Here’s some assets to get you going:

Here are some CSS Custom Properties for your colours:

css
:root {
  --color-primary: #21223e;
  --color-primary-light: #3c3f73;
  --color-success: #0c8d87;
  --color-error: #c01332;
  --color-light: #ffffff;
}
