通过html和css仿制静态页面：采用盒子模型的布局模式
涉及到的标签有：a p div form input img
涉及到的CSS属性组：字体、背景、颜色、外边距、内边距、高宽、定位、浮动、显示等；
盒子模式：主要借助position、float、display实现，控制好content、padding、border、outline、margin
CSS端代码如下：

/* ---------------通用------------------ */
*{
    margin: 0;  /* 消除默认的margin */
    padding: 0;  /* 消除默认的padding */
    position: relative; /* 所有标签的子标签都相对自己定位*/
} 


/* ------------------顶部---------------- */

    /* background-color: limegreen; */

    height: 100px;

    width:292px;

    margin-top:-30px; 
    line-height: 60px;
