Code interpretation

Define dom, define the text of the button in a container, each letter has a span, each span has a data-text attribute, its value is the same as the letter in the span:

 B U T T O N 

The button is centered:

html, body { height: 100%; display: flex; align-items: center; justify-content: center; }

Set the size and text style of the button:

.box { width: 200px; height: 60px; border: 2px solid black; text-align: center; font-size: 30px; line-height: 60px; font-family: sans-serif; }

Each letter of the button is set as an inline block element so that the animation can be set individually:

.box span { display: inline-block; color: blue; }

Stagger the letters Displayed outside the button container, the odd-numbered elements are displayed on top, and the even-numbered elements are displayed below:

.box span:nth-child(odd) { transform: translateY(-100%); } .box span:nth-child(even) { transform: translateY(100%); }

Use pseudo elements to add a copy for each letter:

.box span::before { content: attr(data-text); position: absolute; color: red; }

Let the pseudo elements The letters of the element are also staggered and positioned relative to their original elements:

.box span:nth-child(odd)::before { transform: translateY(100%); } .box span:nth-child(even)::before { transform: translateY(-100%); }
