Giới thiệu 1 số Animation CSS hay trên CodePen
Bài đăng này đã không được cập nhật trong 5 năm
Giới thiệu:
CSS3 animations cho phép bạn thực hiện những hiệu ứng động với hầu hết các đối tượng HTML trên trang web.
Một animation cho phép một đối tượng chuyển đổi từ style này sang một style khác. Trong một animation, bạn có thể thay đổi style nhiều lần với nhiều thuộc tính CSS khác nhau.
Dưới đây là 1 số những animation CSS hay và đẹp mắt.
1. Dodecahedron
Một hình chữ nhật tinh tế, đẹp, tạo ra một hình ảnh động hoàn toàn với CSS.

MANY THANKS TO @tadywankenobi for the following JS to handle the text in the byline:
The following JS takes in the byline and splits it into letters, each one wrapped in a span. We need to create the spans as nodes, we can't just add them to the HTML using innerHTML, as to do so would mean the CSS won't affect the span because it doesn't recognise the tag as existing. It's an old problem we run into time and again.
*/
var byline = document.getElementById('byline'); // Find the H2
bylineText = byline.innerHTML; // Get the content of the H2
bylineArr = bylineText.split(''); // Split content into array
byline.innerHTML = ''; // Empty current content
var span; // Create variables to create elements
var letter;
for(i=0;i<bylineArr.length;i++){ // Loop for every letter
span = document.createElement("span"); // Create a <span> element
letter = document.createTextNode(bylineArr[i]); // Create the letter
if(bylineArr[i] == ' ') { // If the letter is a space...
byline.appendChild(letter); // ...Add the space without a span
} else {

Kết luận:
Để hiểu rõ hơn về Animation, cách tốt nhất là bạn hãy thực hành các ví dụ đơn giản. Có rất nhiều tài liệu hướng dẫn cũng như ví dụ mà bạn có thể dễ dàng tìm thấy trên mạng. Hai link mà tôi khuyên bạn nên đọc là:
