Teacher's comments:不错, 代码完整规范
一, 制作一张商品信息表,内容自定,要求用到行与列的合并
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>商品信息表</title> <style> li{ color: lightgreen; } td{ color: red; background-color: lightblue; } </style> </head> <body> <h3>购物车</h3> <ul> <li>1. 美商海盗船 k95 RGB, 1个, 1399元</li> <li>2. 罗技G903无线鼠标, 2个, 1458元</li> <li>3. LEGION Y7000, 1台, 7399元</li> <li>4.海盗船天行者rgb,1个,1199元</li> </ul> <hr> <table border="1" width="500" cellspacing="0" cellpadding="5"> <caption> <h3>购物车</h3> </caption> <thead> <tr bgcolor="lightblue"> <th>编号</th> <th>名称</th> <th>单价</th> <th>数量</th> <th>金额</th> </tr> </thead> <tr> <td>1</td> <td>美商海盗船 k95 RGB</td> <td>1399</td> <td>1</td> <td>1399</td> </tr> <tr> <td>2</td> <td>罗技G903无线鼠标</td> <td>729</td> <td>2</td> <td>1458</td> </tr> <tr> <td>3</td> <td>LEGION Y7000</td> <td>7299</td> <td>1</td> <td>7299</td> </tr> <tr> <td>4</td> <td>海盗船天行者rgb</td> <td>1199</td> <td>1</td> <td>1199</td> </tr> <tr> <td colspan="3" align="center">合计:</td> <td>5</td> <td>11355</td> </tr> </table> </body> </html>

三,使用绝对定位,实现用户登录框在页面中始终居中显示
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>用户登录框</title> <style> .box{ box-sizing: border-box; width: 600px; height: 600px ; text-align: center; position: absolute; left:50%; top:50%; } .box1{ border: 1px solid black; position: relative; left: -50%; top: -50%; } input{ background-color: lightblue; } </style> </head> <body> <div class="box"> <div class="box1"> <p> <label for="username">用户名:</label> <input type="text" id="username" value="" > </p> <p> <label for="password">密码:</label> <input type="password" id="password" value=""> </p> <p> <button>登录</button> </p> </div> </div> </body> </html>

四, 模仿课堂案例, 实现圣杯布局,并写出完整流程与布局思路
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>圣杯布局</title> <style> header{ height: 60px; background-color: lightslategrey; } main{ box-sizing: border-box; border: 2px solid black; padding-left: 200px; padding-right: 200px; overflow: auto; } main > article{ box-sizing: border-box; background-color: cyan; width: 100%; min-height: 500px; } main > aside { box-sizing: border-box; min-height: 500px; width: 200px; } .left{ background-color: purple; } .right{ background-color: pink; } main > article{ float: left; } .left{ float: left; } .right{ float: left; } .left{ margin-left: -100%; position: relative; left: -200px } .right{ margin-left: -200px; position: relative; left: 200px } footer{ height: 60px; background-color: lightblue; } </style> </head> <body> <header>头部</header> <main> <article>内容区</article> <aside class="left">左侧</aside> <aside class="right">右侧</aside> </main> <footer>底部</footer> </body> </html>

五, (选做): 将圣杯布局中的左右二列,使用绝对定位来实现
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>绝对定位实现圣杯布局</title> <style> *{ padding: 0; margin: 0; } header{ height: 60px; background-color: lightslategrey; } main{ box-sizing: border-box; padding-left: 200px; padding-right: 200px; overflow: auto; } main > article{ box-sizing: border-box; background-color: cyan; width: 100%; min-height: 500px; } main > aside { box-sizing: border-box; min-height: 500px; width: 200px; } .left{ background-color: purple; } .right{ background-color: pink; } main > article{ float: left; } .left{ float: left; } .right{ float: left; } .left{ position: absolute; left:0; top:60px; } .right{ position: absolute; right: 0; top:60px; } footer{ height: 60px; background-color: lightblue; } </style> </head> <body> <header>头部</header> <main> <article>内容区</article> <aside class="left">左侧</aside> <aside class="right">右侧</aside> </main> <footer>底部</footer> </body> </html>

六, (选做): 与圣杯类似的"双飞翼"布局如何实现,并实例演示
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>双飞翼</title> <style > * { margin: 0; padding: 0; text-align: center; } .header, .footer { background-color: skyblue; height: 60px; line-height: 60px; } .container { overflow: hidden; } .main { width: 100%; background-color: purple; height: 100px; line-height: 100px; float: left; } .inner-main { margin-left: 100px; margin-right: 100px; } .left { background-color: pink; width: 100px; height: 100px; line-height: 100px; float: left; margin-left: -100%; } .right { background-color: pink; width: 100px; height: 100px; line-height: 100px; float: left; margin-left: -100px; } </style> </head> <body> <div class="header">头部</div> <div class="container"> <div class="main"> <div class="inner-main">内容区</div> </div> <div class="left">左侧</div> <div class="right">右侧</div> </div> <div class="footer">底部</div> </body> </html>

七,手抄作业

八,总结
①了解了常用的表格制作方法;
②学习了元素的浮动与定位;
float 浮动布局 改变BFC的参照方位
相对定位与绝对定位;
相对定位:元素相对它在文档流中的原来位置,发生偏移;
绝对定位:完全从文档流中接管元素的定位权, 既彻底脱离了文档流;
③学习了PC端布局中, 思路与实现非常经典,具有代表性的"圣杯布局"。
