To do this challenge, you need a good understanding of HTML, CSS and JavaScript.

The challenge

Your challenge is to build out this calculator app and get it looking as close to the design as possible.

Your users should be able to:

  • See the size of the elements adjust based on their device's screen size
  • Perform mathematical operations like addition, subtraction, multiplication, and division
  • Adjust the color theme based on their preference
  • Bonus: Have their initial theme preference checked using prefers-color-scheme and have any additional changes saved in the browser

Where to find everything

Your task is to build out the project to the designs inside the /design folder. You will find both a mobile and a desktop version of the design.

There is also a style-guide.md file containing the information you'll need, such as color palette and fonts.
