Desktop and mobile responsive to-do list, using HTML, CSS and JS.

Hey there.

Just finished this challenge. I have a few features that I didn't finish completely:

1. the checkbox - I couldn't use gradient on a circle so it appeared a square.
2. At the beginning I thought I need to create a light theme and a dark theme for operation system "prefers-color-scheme". Only later I realized I need to create a toggle with the "sun/moon" images. So I didn't create one, but the site is theme responsive.
3. I didn't create a drag and drop feature in the mobile version so its not working.

Other than that I think I did a pretty good job. I learned a lot.
