Overview

The challenge

Users should be able to:

• View the optimal layout for the app depending on their device's screen size
• See hover states for all interactive elements on the page
• Add new todos to the list
• Mark todos as complete
• Delete todos from the list
• Filter by all/active/complete todos
• Clear all completed todos
• Toggle light and dark mode
• Drag and drop to reorder items on the list

• CSS Grid
• SASS
• JavaScript

What I learned

Adding border with gradient and radius:

.task:hover .check-box {
  border-radius: 50px;
  border: 2px solid transparent;
  background: var(--bg-gradient) border-box;
  -webkit-mask: linear-gradient(var(--Very-Light-Gray) 0 0) padding-box, linear-gradient(
      var(--Very-Light-Gray) 0 0
    );
  -webkit-mask-composite: xor;
  mask-composite: exclude;
}

Adjust background-image to stretch but not shrink:

.app {
  background-repeat: no-repeat;
  background-size: 100% 30rem;
}
@media (max-width: 1440px) {
  .app {
    background-size: auto 30rem;
    background-position-x: center;
  }
}

Swap items in an array using array destructuring

[this.tasksArr[draggedElIndex], this.tasksArr[targetElIndex]] = [
  this.tasksArr[targetElIndex],
  this.tasksArr[draggedElIndex],
];

Continued development

• I guess the CSS implementation of dark mode need to be refactored.
• The application should have a reset button to remove data in local storage.

Useful resources

• DEV Community - This helped me figure out how to implement the gradient circular border.
