A simplified effect on the Google Homepage

Source: Internet
Author: User

I have always liked the special effects of those seven points on the Google homepage! In my spare time today, I found its originalCodeIt is too difficult to understand. Fortunately, it is relatively easy to find a simple code that imitates the special effects on the Google homepage, but there are still many points that you cannot understand. It seems that my Js + CSS water products are far behind each other. I 'd like to add it to my favorites and study it slowly. I hope I can understand it later ~~~

Run the following code:

<! Doctype HTML public "-// W3C // dtd xhtml 1.0 transitional // en" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<Title> </title>
<Style type = "text/CSS">
