Text chuyển động với css

Để tạo ra một website ấn tượng thì design, hay "bộ mặt" của trang web là cực kỳ quan trọng. Trong design nói chung thì tiêu đề, đầu đề lại là thứ đập vào mắt người dùng đầu tiên, vì vậy gây ấn tượng bằng tiêu đề sẽ đem lại hiệu quả nhiều nhất.

Từ cách đây vài năm designer đã cặm cụi với Photoshop để tạo ra các hiệu ứng chữ đẹp, export ra thành file ảnh để nhúng vào web, hay dùng flash để tạo animation. Tuy nhiên với sự phát triển của HTML5 và CSS3 thì quan niệm và cách làm đã thay đổi hoàn toàn. Giờ đây chỉ với CSS (và một chút JS) thì đã có thể tạo ra rất nhiều hiệu ứng chữ đẹp mắt đến đáng kinh ngạc.

Mình đã xem và thấy có nhiều bài viết rất hay. Hôm nay mình demo lại một bài viết với hiệu ứng chữ đẹp.
