css code

td{
    padding-left: 100px;
    padding-bottom: 100px;
    padding-right: 50px;
    padding-top: 50px;
}
/*padding控制着内容距离边距的距离，如果只是padding后面接一个值，就是上下左右都是这个值
这是分开对上下左右进行设置*/

#p1{
    border-top-style: groove;
    border-top-width: 5px;
    border-top-color: deepskyblue;
}
/*控制着主体内容外面一点的边框，同上面一样可以分别控制四个部分border-top-style控制上边框，
如果上面的属性，就是控制上面左右的边框效果是相同的,border-width,border-top-color同上*/

#p2{
    border-radius: 15px;
    width: 400px;
    text-align: center;
    background-color: deepskyblue;
    border: 4px solid fuchsia;
}
/*border-radius增加边框边角的效果 ,border-image是添加边框图片*/

#p3{
    width: 100px;
    height: 100px;
    text-align: center;
    color: red;
    background-color: aqua;
    box-shadow: 10px 10px 5px cornflowerblue;

/*box-shadow是边框阴影效果,第一个属性是向右偏移多少，
第二个是向下，第三个是程度，第四个就是阴影的颜色*/
