BoxScroll

Simple implementation of carousel effects for common images. You can control the number list or press the left or right buttons. The logic is very simple. At the end of the process, you have to go back and see the annotations.

The Code is as follows:

HTML

<! Doctype html> <meta http-equiv = "Content-Type" content = "text/html; charset = UTF-8 "/> <meta content =" "name =" keywords "/> <meta content =" "name =" description "/> <meta name =" author "content = "codetker"/> 
CSS
@ Charset "UTF-8";/* CSS Document */body {margin: 0 0; padding: 0 0; height: 100%; width: 100% ;}. wrap {font-family: "", "", Times, "Times New Roman", serif; font-size: 14px; margin: 0 0; padding: 0 0; height: 100%; width: 100%; overflow: hidden ;}. boxStyle {/* photo size */width: 500px; height: 256px ;}. scrollBox {position: relative; width: 500px; margin: 0 auto ;}. picInnerBox {width: pixel PX;/* You can just put it down. If you need to scroll up or down, change height */overflow: hidden ;}. picInnerBox li {cursor: pointer; float: left ;}. picOuterBox {overflow: hidden ;}. arrow {position: absolute; top: 45%; height: 40px; cursor: pointer; z-index: 99 ;}. arrow: hover {color: # fff ;}. arrowLeft {float: left; left: 5% ;}. arrowRight {float: right; right: 5% ;}. picControl {overflow: auto; width: 100px; margin: 0 auto ;}. picControl ul li {cursor: pointer; float: left; width: 20px; height: 20px; text-align: center ;}. picControl ul li: hover {color: red ;}. liSelected {color: red ;}
