变色.html

<!DOCTYPE html>

<html>

    <head>

        <meta charset="UTF-8">

        <title>media</title>

        <style type="text/css">

            body {

                /*取消默认的外间距*/

                margin: 0px;

            }

            main {

                margin: 5px;

                /*对子元素开启弹性布局*/

                display: flex;

                /*换行*/

                flex-wrap: wrap;

            }

            div {

                /*将每个div默认4个一行四列*/

                width: calc((100% - 40px) / 4);

                height: 200px;

                background-color: pink;

                margin: 5px;

            }

            /*媒体查询：检索不同视口宽度*/

            @media (max-width:1280px) {

                /*在宽度小于等于1280时的样式*/

                div {

                    background-color: #FFFF00;

                }

            }

            @media (max-width:800px) {

                div {

                    background-color: aqua;

                    width: calc((100% - 30px) / 3);

                }

            }

            @media (max-width:500px) {

                div {

                    background-color: blueviolet;

                    width: calc((100% - 20px) / 2);

                }

            }

            @media (max-width:350px) {

                div {

                    background-color: chartreuse;

                    width: calc((100% - 10px) / 1);

                }

            }

        </style>

    </head>

    <body>

        <!--main>div{??}*20-->

        <main>

            <div>1</div>

            <div>2</div>

            <div>3</div>

            <div>4</div>

            <div>5</div>

            <div>6</div>

            <div>7</div>

            <div>8</div>

            <div>9</div>

            <div>10</div>

            <div>11</div>

            <div>12</div>

            <div>13</div>

            <div>14</div>

            <div>15</div>

            <div>16</div>

            <div>17</div>

            <div>18</div>

            <div>19</div>

            <div>20</div>

        </main>

    </body>

</html>

后来基本就打酱油了///

下周也不计划去了。。。。

稍微了解了一下html基本结构就好了。。。

网上资源。http://www.w3school.com.cn

没style的：

<!DOCTYPE html>

<html>

    <head>

        <meta charset="UTF-8">

        <title></title>

    </head>

    <body>

        <header>

            <h1>City Gallery</h1>

        </header>

        <nav>

            London<br>

            Paris<br>

            Tokyo<br>

        </nav>

        <section>

            <h1>London</h1>

            <p>London is the capital city of England. It is the most populous city in the United Kingdom,

with a metropolitan area of over 13 million inhabitants.</p>

            <p>Standing on the River Thames, London has been a major settlement for two millennia,

its history going back to its founding by the Romans, who named it Londinium.

</p>

        </section>

        <footer>

        </footer>

    </body>

</html>

通过添加style就可以变成各种样子：

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
<style type="text/css">
header {
background-color:black;
color:white;
text-align:center;
padding:5px;
}

nav {
line-height:30px;
background-color:#eeeeee;
height:300px;
width:100px;
float:left;
padding:5px;
}

section {
width:350px;
float:left;
padding:10px;
}
footer {
background-color:black;
color:white;
clear:both;
text-align:center;
padding:5px;
}
</style>
</head>
<body>
<header>
<h1>City Gallery</h1>
</header>

<nav>
London<br>
Paris<br>
Tokyo<br>
</nav>

<section>
<h1>London</h1>
<p>London is the capital city of England. It is the most populous city in the United Kingdom,
with a metropolitan area of over 13 million inhabitants.</p>
<p>Standing on the River Thames, London has been a major settlement for two millennia,
