    <style>
        /*默认的颜色*/
        a{
            text-decoration: none;
            color: black;
        }
        /*鼠标悬浮的状态(只需要记住：hover)*/
        a:hover{
            color: orange;
            font-size: 50px;
        }
        /*鼠标按住未释放的状态*/
        a:active{
            color: green;
        }
        a:visited{
            color: red;
        }
        /*text-shadow:阴影颜色,水平偏移，垂直偏移，阴影半径*/
        #price{
            text-shadow: #5c88c9 10px -10px 2px;
        }
    </style>

2、列表样式练习

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <link rel="stylesheet" href="css/style.css">
</head>
<body>
<div id="nav">
    <h2 class="title">全部商品分类</h2>
    <ul>
        <li><a href="#">图书</a>&nbsp;&nbsp;<a href="#">音响</a>&nbsp;&nbsp;<a href="#">数字商品</a></li>
        <li><a href="#">家用电器</a>&nbsp;&nbsp;<a href="#">手机</a>&nbsp;&nbsp;<a href="#">数码</a></li>
        <li><a href="#">电脑</a>&nbsp;&nbsp;<a href="#">办公</a></li>
        <li><a href="#">家居</a>&nbsp;&nbsp;<a href="#">家装</a>&nbsp;&nbsp;<a href="#">厨具</a></li>
        <li><a href="#">服饰鞋帽</a>&nbsp;&nbsp;<a href="#">个护化妆</a></li>
        <li><a href="#">礼品箱包</a>&nbsp;&nbsp;<a href="#">中标</a>&nbsp;&nbsp;<a href="#">珠宝</a></li>
        <li><a href="#">食品饮料</a>&nbsp;&nbsp;<a href="#">保健食品</a></li>
        <li><a href="#">彩票</a>&nbsp;&nbsp;<a href="#">旅行</a>&nbsp;&nbsp;<a href="#">充值</a>&nbsp;&nbsp;<a href="#">票务</a></li>
    </ul>
</div>
</body>
</html>

#nav{
    width: 225px;
    background:chocolate ;
}


.title{
    font-size: 18px;
    font-weight: bold;
    text-indent: 1em;
    line-height: 35px;
    background: #cb2c2c;
}
/*ul li
list-style:
none 去掉圆点
circle 空心圆
decimal 数字
square 正方形
*/

/*ul{*/
/*    background: chocolate;*/
/*}*/

ul li{
    height: 30px;
    list-style: none;
    text-indent: 1em;
}

a{
    text-decoration: none;
    font-size: 14px;
    color: black;
}

a:hover{
color: orange;
    text-decoration: underline;
}

3、背景图像应用及渐变

<style>
div{
    width: 1000px;
    height: 700px;
    border: 1px solid red;
    background-image: url("images/1.jpg");
    /*默认是全部平铺的 repeat*/
}
.div1{
    background-repeat: repeat-x;
}
.div2{
    background-repeat: repeat-y;
}
.div3{
    background-repeat: no-repeat;
}
</style>

渐变

background-color: #4158D0;
background-image: linear-gradient(43deg, #4158D0 0%, #C850C0 46%, #FFCC70 100%);

4、盒子模型及边框使用

Java自学-CSS(3)_盒子模型_03

<style>
/*body总有一个默认的外边距margin: 0  常见操作*/
/*h1,ul,li,a,body{*/
/*     margin: 0;*/
/*    padding: 0;*/
/*    text-decoration: none;*/
/* }*/
/*border:.粗细，样式，颜色*/
#box{
    width: 300px;
    border: 1px solid red ;
    line-height: 30px;
}

h2{
    font-size: 16px;
    background: orange;
    margin: 0;
    line-height: 30px;
    color: white;
}

form{
    background: green;
}

div:nth-of-type(1) input{
    border: 3px solid black;
}
div:nth-of-type(2) input{
    border: 3px dashed red;
}
div:nth-of-type(3) input{
    border: 2px dashed rgba(56, 220, 60, 0.46);
}
</style>

5、内外边距及div居中

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>

    <!--外边距的妙用:居中元素
     margin: 0 auto;-->
    <style>
        /*body总有一个默认的外边距margin: 0  常见操作*/
        /*h1,ul,li,a,body{*/
        /*     margin: 0;*/
        /*    padding: 0;*/
        /*    text-decoration: none;*/
        /* }*/
        /*border:.粗细，样式，颜色*/
        #box{
            width: 300px;
            border: 1px solid red ;
            margin: 0 auto;
        }

        /*顺时针旋转
        margin: 0
        margin:0 1px
        margin:0 1px 2px 3px
        */

        h2{
            font-size: 16px;
            background-color: orange;
            line-height: 30px;
            color: white;
            margin:0 1px 2px 3px
        }

        form{
            background: green;
        }

       input{
           border: 1px solid black;
       }

       div:nth-of-type(1){
           padding: 10px 5px;
       }
    </style>
</head>
<body>

<div id="box">
    <h2>会员登录</h2>
    <form action="#">
        <div>
            <span>用户名：</span>
            <input type="text">
        </div>
        <div>
            <span>密码：</span>
            <input type="text">
        </div>
        <div>
            <span>邮箱：</span>
            <input type="text">
        </div>
    </form>
</div>

</body>
</html>
