2. Variables in the CSS

Declaring variable in the CSS, use double dash at the begining of the variable names

:root { 
  --primaryColor: #fff; 
  --navColor1: #21292c; 
  --navColor2: #aa3e39; 
  --navColor3: #aa6e39; 
  --navColor4: #236267; 
  --navColor5: #2c8437; 
}

The :root CSS pseudo-class matches the root element of a tree representing the document. In HTML, :root represents the element and is identical to the selector html, except that its specificity is higher.

Using variable in the context

nav li:nth-of-type(1) { 
	background-color: var(--navColor1); 
} 

Note on the :nth-of-type, the :nth-of-type(n) selector matches every element that is the nth child, of a particular type, of its parent.

3. Slide animation for the overlay

.overlay {
  position: fixed;
  z-index: 9;
  left: 0;
  top: 0;
  width: 100vw;
  height: 100vh;
  background-color: rgba(0, 0, 0, 0.7);
  transform: translateX(-100vw);
}

.overlay-slide-right {
  transition: all 0.4s ease-in-out;
  transform: translateX(0);
}

.overlay-slide-left {
  transition: all 0.8s ease-in-out;
  transform: translateX(-100vw);
}

4. Slide in animation with delay for each navigation item

.slide-in-1 {
  animation: slide-in 0.4s linear 0.2s both;
}

.slide-in-2 {
  animation: slide-in 0.4s linear 0.4s both;
}

@keyframes slide-in {
  from {
    transform: translateX(-100%);
  }

  to{
    transform: translateX(0);
  }
}
