(编辑:jimmy 日期: 2024/11/28 浏览:3 次 )
在web项目中我们经常要使用时间轴(timeline)控件。本文提供一种基于CSS3的可逐项展开的timeline,在各展开项中可以嵌入文本、图片、视频等元素。运行效果如下:
实现
该控件的实现过程较为简单,主要由test.html
文件和timeline.css
文件组成。具体代码如下:
1、test.html文件
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <link rel="stylesheet" href="timeline.css"/> <title>Timeline</title> </head> <body> <div id='timeDiv'> <ul id='timeline'> <li class='work'> <input class='radio' id='work1' name='works' type='radio' checked> <div class="relative"> <label for='work1'>1、标题一</label> <span class='date'>T1</span> <span class='circle'></span> </div> <div class='content'> <p> 长安元年(701年),李白,字太白。其生地今一般认为是唐剑南道绵州(巴西郡)昌隆(后避玄宗讳改为昌明)青莲乡。祖籍为甘肃天水。 其家世、家族皆不详。据《新唐书》记载,李白为兴圣皇帝(凉武昭王李暠)九世孙,按照这个说法李白与李唐诸王同宗,是唐太宗李世民的同辈族弟。 亦有说其祖是李建成或李元吉。 </p> <p><img src="http://i.qulishi.com/UploadFile/2014-7/2014725171362.jpg" /></p> </div> </li> <li class='work'> <input class='radio' id='work2' name='works' type='radio'> <div class="relative"> <label for='work2'>2、标题二</label> <span class='date'>T2</span> <span class='circle'></span> </div> <div class='content'> <p> 神龙元年(705年), 十一月,武则天去世。李白五岁。发蒙读书始于是年。 《上安州裴长史书》云:“五岁诵六甲。”六甲,唐代的小学识字课本,长史,州之次官。 </p> </div> </li> <li class='work'> <input class='radio' id='work3' name='works' type='radio'> <div class="relative"> <label for='work3'>3、标题三</label> <span class='date'>T3</span> <span class='circle'></span> </div> <div class='content'> <p> 开元三年(715年),李白十五岁。 已有诗赋多首,并得到一些社会名流的推崇与奖掖,开始从事社会干谒活动。 亦开始接受道家思想的影响,好剑术,喜任侠。是年岑参生。 </p> </div> </li> <li class='work'> <input class='radio' id='work4' name='works' type='radio'> <div class="relative"> <label for='work4'>4、标题四</label> <span class='date'>T4</span> <span class='circle'></span> </div> <div class='content'> <p> 开元六年(718年),李白十八岁。 隐居戴天大匡山(在今四川省江油市内)读书。 往来于旁郡,先后出游江油、剑阁、梓州(州治在今四川省境内)等地,增长了不少阅历与见识。 </p> </div> </li> </ul> </div> </body> </html>
2、timeline.css文件
