My questions are:

  1. How do I round the result correctly? For example, if you add 0.1 and 0.2 you get 0.3000000000000000004. How do I get 0.3?
  2. When switching the theme on a mobile device, the radio buttons and pseudo elements on the switch are highlighted for a moment. How can this be fixed?

    Hi Oleg,

    to round the number you can use the toFixed method.

    0.3000000000000000004.toFixed(1)

    Will round it to 0.3

    I hope this helps.

    Here's the MDN docs for toFixed:
