Code Interpretation

Define dom, the container is an unordered list, and the list items represent buttons:


        
  • home

Centered display:

body {
  margin: 0;
  height: 100vh;
  display: flex;
  align-items: center;
  justify-content: center;
  background: linear-gradient(deepskyblue, navy);
}

Remove the symbol in front of the list item:

ul {
  padding: 0;
  list-style-type: none;
}

Set the text style of the button:

ul li {
  color: #ddd;
  font-size: 25px;
  font-family: sans-serif;
  text-transform: uppercase;
}

Use pseudo elements to add a box to the left of the button:

ul li {
  position: relative;
}

ul li::before {
  content: '';
  position: absolute;
  width: 100%;
  height: 100%;
  background: tomato;
  left: -100%;
}

Use pseudo elements Add an underline to the right of the button:

ul li::after {
  content: '';
  position: absolute;
  width: 100%;
  height: 0.2em;
  background: tomato;
  bottom: 0;
  left: 100%;
}

Next set the mouseover effect.
When the mouse is hovering, the box on the left moves to the position of the text:

ul li::before {
  transition: 0.4s ease-out;
}

ul li:hover::before {
  left: 100%;
}

The underline on the right moves to the position of the text, and its animation time is delayed until the animation of the box is about to end before starting. :

ul li::after {
  transition: 0.3s 0.3s ease-out;
}

ul li:hover::after {
  left: 0%;
}

At the same time, increase the brightness of the text:

ul li {
  transition: 0.3s;
  cursor: pointer;
}

ul li:hover {
  color: #fff;
}

Hide the part outside the button so that the squares and underlines are invisible by default. They only change from both sides when the mouse is hovered. Side entry:

ul li {
  overflow: hidden;
}

Finally, add a few more buttons to the dom:


        
  • home
  •     
  • products
  •     
  • services
  •     
  • contact

Lay out multiple buttons:

ul {
  display: flex;
  flex-direction: column;
  align-items: center;
}

ul li {
  margin: 0.5em;
}

You’re done!
