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-1280px) { /*在宽度小于等于1280时的样式*/ div { background-color: #FFFF00; } } @media (max-800px) { div { background-color: aqua; width: calc((100% - 30px) / 3); } } @media (max-500px) { div { background-color: blueviolet; width: calc((100% - 20px) / 2); } } @media (max-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///

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> Copyright W3School.com.cn </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;
100px;
float:left;
padding:5px;
}
section {
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>
