Challenge #003 - Duotone Card

- Takes about 3 minutes to complete

Duotone is a lovely effect which we can finally achieve with CSS. Popularised by Spotify: it’s become a very common design treatment on the web, so let’s have some fun and make a set of duotone cards.

This third challenge is free to participate, but the solution to the challenge will be for paying members only, so subscribe to see the upcoming solution.

What you’re building

Demo shows the collection of three cards, headed with "Meet the team". The hover state on the first card shows the duotone effect being removed and a caret revealing itself.

The brief

Take the design assets and re-create these duotone cards whatever front-end technology you want. Consider how the cards work responsively, too. How do they stack, or do they even stack at all? 🤔

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)

Bonus points awarded if:

  • You use modern CSS
  • Your solution is lightweight and performant
  • Your solution is fully accessible
  • You create appropriate transitions and/or animations between states

  --color-navy-opaque: rgba(6, 0, 79, 0.77);
  --color-light: #ffffff;
  --color-dark: #252525;
