1.制作一个个性表格（较源代码添加了表头阴影text-shadow和表格标题caption）
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>菜鸟教程(runoob.com)</title> <style> #customers { font-family:"Trebuchet MS", Arial, Helvetica, sans-serif; width:100%; border-collapse:collapse; } #customers td, #customers th { font-size:1em; border:1px solid #98bf21; padding:3px 7px 2px 7px; } #customers th { font-size:1.1em; text-align:left; padding-top:5px; padding-bottom:4px; background-color:#A7C942; color:#ffffff; text-shadow:2px 2px #a08fa0; } #customers tr.alt td { color:#000000; background-color:#EAF2D3; } caption {caption-side:bottom;} </style> </head> <body> <table id="customers"> <caption>Table 1.1</caption> <tr> <th>Company</th> <th>Contact</th> <th>Country</th> </tr> <tr> <td>Alfreds Futterkiste</td> <td>Maria Anders</td> <td>Germany</td> </tr> <tr class="alt"> <td>Berglunds snabbköp</td> <td>Christina Berglund</td> <td>Sweden</td> </tr> <tr> <td>Centro comercial Moctezuma</td> <td>Francisco Chang</td> <td>Mexico</td> </tr> <tr class="alt"> <td>Ernst Handel</td> <td>Roland Mendel</td> <td>Austria</td> </tr> <tr> <td>Island Trading</td> <td>Helen Bennett</td> <td>UK</td> </tr> <tr class="alt"> <td>Königlich Essen</td> <td>Philip Cramer</td> <td>Germany</td> </tr> <tr> <td>Laughing Bacchus Winecellars</td> <td>Yoshi Tannamuri</td> <td>Canada</td> </tr> <tr class="alt"> <td>Magazzini Alimentari Riuniti</td> <td>Giovanni Rovelli</td> <td>Italy</td> </tr> <tr> <td>North/South</td> <td>Simon Crowther</td> <td>UK</td> </tr> <tr class="alt"> <td>Paris spécialités</td> <td>Marie Bertrand</td> <td>France</td> </tr> </table> </body> </html>
注意区分：id选择器#，class选择器.，分组选择器（其中逗号表示并列关系）
