写在前,定义文档类型,大小写均可。html标签:其作用是告知浏览器其自身是一个 HTML 文档。


还没有写完,后续持续更新

首先来熟悉一下html的基本结构

<!DOCTYPE HTML>  <html> <head> <meta charset="utf-8"> <title>标题</title> </head> <body> 这里是文档的主体 <!--这是一行注释,注释不会在浏览器中显示!--> </body> </html> 

<!DOCTYPE HTML>

写在前,定义文档类型,大小写均可。

<html></html>

html标签:其作用是告知浏览器其自身是一个 HTML 文档。

<head></head>

Head标签:其作用是定义关于文档的信息。其中的元素可以引用脚本、指示浏览器在哪里找到样式表、提供元信息

<meta charset= "utf-8" />

页面编码
常用的编码格式有utf-8和gb2312(中文), 在标签内定义
其目的是告知浏览器此页面属于什么字符编码格式

<title></title>

Title标签:通常放在浏览器窗口的标题栏或状态栏上

<body></body>

Body标签:定义文档的主体,我们所敲得代码主要在这里面

<!-- -->

注释
例:

<!--这是一行注释--> 

<br />

用于换行

特殊字符

&gt;		大于号 (>) &lt;		小于号 (<) &quot;		引号 (") &#8220;		左引号 (") &#8221;		右引号 (") &reg;		注册商标(®)	 &#8482;		注册商标(™) &reg;		版权(©)	 &amp;		and(&) &#8212;		破折线(—) &#8211;		短破折线(–) &pound;		英镑(£) &#8364;		欧元(€) &yen;		日元(¥) &nbsp;		占位符,表示1个空格,直接敲空格无论连续敲多少个,都只显示一个空格,用&nbsp;敲几次就有几个空格 

<!doctype html> <html> <head> <meta charset="utf-8"> <title>特殊符号</title> </head>  <body> <p>大于号&gt;</p> <p>小于号&lt;</p> <p>引号&quot;</p> <p>左引号&8220;</p> <p>右引号&8221;</p> <p>版权&reg;</p> <p>注册商标&8482;</p> <p>and&amp;</p> <p>破折线&#8212;</p> <p>短破折线&#8211;</p> <p>英镑&pound;</p> <p>欧元&#8364;</p> <p>日元&yen;</p> <p>十个个空格          直接敲得</p> <p>十个空格&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;用占位符表示</p> </body> </html> 

<p></p>

段落标签
可以利用align来对段落进行左中右对齐。align的值为left, center, right, justify
其中justify是对行进行伸展,这样每行都可以有相等的长度

<!doctype html> <html> <head> <meta charset="utf-8"> <title>段落</title> </head>  <body> <P>这是一个最基本的段落</p> <P align="left">这是一个左对齐的段落</p> <P align="right">这是一个右对齐的段落</p> <P align="center">这是一个居中的段落</p> <center><P>这是一个用&lt;center&gt;居中的段落</p></center> <P align="justify">每行都可以有相等的长度</p> <!--感觉justify好像没有什么用,那位大佬可以指点一下--> </body> </html>  

标题。

标题一共有6级,分别为<h1>~<h6>
从一级至六级,字体依次减小
例:

<!doctype html> <html> <head> <meta charset="utf-8"> <title>标题</title> </head>  <body> <h1>这是一级标题</h1> <h2>这是二级标题</h2> <h3>这是三级标题</h3> <h4>这是四级标题</h4> <h5>这是五级标题</h5> <h6>这是六级标题</h6> <!-zhi--> <p>&nbsp;</p> </body> </html> 

文本格式

<strong>	粗体 <em>		斜体 <sup>		字的上标 <sub>		字的下标 

例:

<!doctype html> <html> <head> <meta charset="utf-8"> <title>标题</title> </head>  <body> <p> 正常<br/> <strong>粗体</strong><br/> <em>斜体</em><br/> x<sup>2</sup><br/> x<sub>1</sub> </p> </body> </html> 

有序列表

<ul><li></li></ul> type= disc/circle/square disc				实心圆点    circle				为空心圆 square				正方形 

无序列表

Type=1/a/A/i/I 

例:

<!doctype html> <html> <head> <meta charset="utf-8"> <title>视频</title> </head>  <body> <ul type="circle">   <li>pubg</li>   <li>Ring of Elysium</li>   <li>Cyberpunk 2077</li>   <li>lol</li>   <li>gta</li> </ul> <ul type="disc">   <li>pubg</li>   <li>Ring of Elysium</li>   <li>Cyberpunk 2077</li>   <li>lol</li>   <li>gta</li> </ul> <ul type="square">   <li>pubg</li>   <li>Ring of Elysium</li>   <li>Cyberpunk 2077</li>   <li>lol</li>   <li>gta</li> </ul> <ol type="1">   <li>pubg</li>   <li>Ring of Elysium</li>   <li>Cyberpunk 2077</li>   <li>lol</li>   <li>gta</li> </ol> <ol type="a">   <li>pubg</li>   <li>Ring of Elysium</li>   <li>Cyberpunk 2077</li>   <li>lol</li>   <li>gta</li> </ol> <ol type="A">   <li>pubg</li>   <li>Ring of Elysium</li>   <li>Cyberpunk 2077</li>   <li>lol</li>   <li>gta</li> </ol> <ol type="i">   <li>pubg</li>   <li>Ring of Elysium</li>   <li>Cyberpunk 2077</li>   <li>lol</li>   <li>gta</li> </ol> <ol type="I">   <li>pubg</li>   <li>Ring of Elysium</li>   <li>Cyberpunk 2077</li>   <li>lol</li>   <li>gta</li> </ol> </body> </html> 

超链接

超链接可以是一个字,一个词,或者一组词,一幅图,通过点击这些内容来跳转到指定的界面,当鼠标移动到超链接上时,箭头会变为一只小手

<a href=”tel:电话号码”>拨打指定电话</a> <a href="sms: 电话号码">发送短信到指定号码</a> <a href = "mailto:邮件地址">向指定邮箱发送电子邮件</a> <a href = "ftp://服务器IP地址或域名">访问指定服务器</a> <a href = "telnet://服务器IP地址或域名">访问指定服务器</a> 

例:

<!doctype html> <html> <head> <meta charset="utf-8"> <title>超链接</title> </head>  <body> <p> <a href="https://www.cnblogs.com/yphnb/">欢迎访问我的博客</a><br/> <a href="https://www.cnblogs.com/yphnb/" target="_blank">欢迎访问我的博客</a><br/> <!-- target="_blank"表示在新的窗口打开这个链接--> <a href="tel:110">报警电话</a> <a href="sms: 110">发送短信到指定号码</a> <!--信息电脑好像不能用--> <a href = "mailto:yupengsmail@gmail.com">给我发电子邮件</a> <a href = "ftp://服务器IP地址或域名">访问指定服务器</a> <a href = "telnet://服务器IP地址或域名">访问指定服务器</a> </p> <!-zhi--> <p>&nbsp;</p> </body> </html> 

锚点

<a href="#所取名字"> </a>		#号不能省略! <a name="所取名字"> </a>  

例:

<!doctype html> <html> <head> <meta charset="utf-8"> <title>锚点</title> </head>  <body> <center>  <p>点击以下按钮,直达歌词目录</p> <a href="#maodian0">My Heart Will Go On</a><br /> <!--指向指定位置的锚点--> <a href="#maodian1">Bohemian Rhapsody</a><br /> <a href="#maodian2">Call Me Maybe</a><br />  <a name="maodian0"><h3>My Heart Will Go On</h3></a> <!--<a name="maodian0"></a>,这是一个锚点,用于定位--> <p>Every night in my dreams<br>   I see you<br>   I feel you<br>   That is how I know you go on<br>   Far across the distance<br>   And spaces between us.<br>   You have come to show you go on<br>   Near far,<br>   wherever you are<br>   I believe that the heart does go on<br>   Once more,<br>   you open the door,<br>   And you're here in my heart.<br>   And my heart will go on and on<br>   Love can touch us one time.<br>   And last for a lifetime<br>   And never let go till we're gone,<br>   Love was when I loved you<br>   One true time I hold to.<br>   In my life we'll always go on.<br>   Near far,<br>   wherever you are<br>   I believe that the heart does go on<br>   Once more,<br>   you open the door,<br>   And you're here in my heart,<br>   And my heart will go on and on<br>   You're here,<br>   You're here,<br>   there's nothing I fear.<br>   And I know that my heart will go on<br>   we'll stay forever this way.<br>   You are safe in my heart,<br> and my heart will go on and on</p> <p>&nbsp;</p> <p>&nbsp;</p>  <a name="maodian1"><h3>Bohemian Rhapsody </h3></a> <p>Is this the real life</p> <p>Is this just fantasy</p> <p>Caught in a landslide</p> <p>No escape from reality</p> <p>Open your eyes, look up to the skies and see</p> <p>I'm just a poor boy, (oooh, poor boy)</p> <p>I need no sympathy</p> <p>Because I'm easy come, easy go</p> <p>Little high, little low</p> <p>Anyway the wind blows, doesn't really matter to me</p> <p>To me</p> <p>Mama, just killed a man</p> <p>Put a gun against his head</p> <p>Pulled my trigger now he's dead</p> <p>Mama, life had just begun</p> <p>But now I've gone and thrown it all away</p> <p>Mama, oooh, ooh, ooh, ooh</p> <p>Didn't mean to make you cry</p> <p>If I'm not back again this time tomorrow</p> <p>Carry on, carry on, as if nothing really matters</p> <p>Too late, my time has come</p> <p>Sends shivers down my spine</p> <p>Body's aching all the time</p> <p>Goodbye everybody, I've got to go</p> <p>Gotta leave you all behind and face the truth</p> <p>Mama, oooh, ooh, ooh, ooh</p> <p>(Anyway the wind blows)</p> <p>I don't wanna die</p> <p>I sometimes wish I'd never been born at all</p> <p>I see a little silhouetto of a man</p> <p>Scaramouche, Scaramouche will you do the fandango?</p> <p>Thunderbolts and lightning</p> <p>Very, very frightening me</p> <p>Galileo, galileo</p> <p>Galileo, galileo</p> <p>Galileo, figaro</p> <p>Magnifico-o-o-o-oh</p> <p>I'm just a poor boy, nobody loves me</p> <p>He's just a poor boy from a poor family</p> <p>Spare him his life from this monstrosity</p> <p>Easy come, easy go, will you let me go</p> <p>Bismillah!
