HTML零基础,快速学习/复习
还没有写完哈,后续持续更新,喜欢就加一个关注哈!
首先来熟悉一下html的基本结构
代码实例 <--可以直接打开
<!DOCTYPE HTML>
<html>
<head>
<meta charset=\"utf-8\">
<title>标题</title>
</head>
<body>
这里是文档的主体<br />
这里是文档的主体<br />
这里是文档的主体<br />
这里是文档的主体<br />
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>
HTML规范
<!DOCTYPE HTML>
写在<html>前,定义文档类型,大小写均可。
html标签
<html></html>
其作用是告知浏览器其自身是一个 HTML 文档。
Head标签
<head></head>
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 、
页面编码
<meta charset= \"utf-8\" />
常用的编码格式有utf-8和gb2312(中文), 在<head></head>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标签
<title></title>
通常放在浏览器窗口的标题栏或状态栏上
Body标签:
<body></body>
定义文档的主体,我们所敲得代码主要在这里面
注释
<!-- 这里填注释内容 -->
换行
<br />
用于换行
特殊字符
> | 大于号 (>) |
< | 小于号 (<) |
" | 引号 (\") |
“ | 左引号 (\") |
” | 右引号 (\") |
® | 注册商标(®) |
™ | 注册商标(™) |

— | 破折线(—) |
– | 短破折线(–) |
£ | 英镑(£) |
€ | 欧元(€) |
¥ | 日元(¥) |
| 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 敲几次就有几个空格 |

<p>十个空格 用占位符表示</p>
</body>
</html>
段落标签
<p></p>
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
代码实例 <--可以直接打开
<!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<center>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:
代码实例 <--可以直接打开
<!DOCTYPE HTML>
<html>
<head>
<meta charset=\"utf-8\">
<title>标题</title>
</head>

<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>

<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> </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! No, we will not let you go, let him go</p>
<p>Bismillah! We will not let you go, let him go</p>
<p>Bismillah! We will not let you go, let me go</p>
<p>Will not let you go, let me go</p>
<p>Never, never, never, never let me go-o-o-o-oh (Never let you go)</p>
<p>No, no, no, no, no, no, no</p>
<p>Oh, mama mia, mama mia</p>
<p>Mama mia let me go</p>
<p>Beelzebub has a devil put aside for me, for me, for me</p>
<p>So you think you can stone me and spit in my eye?</p>
<p>So you think you can love me and leave me to die?</p>
<p>Oh, baby, can\'t do this to me baby</p>
<p>Just gotta get out, just gotta get right outta here</p>
<p>Ooooh, ooooh, ooooh</p>
<p>Oooh yeah, oooh yeah</p>
<p>Nothing really matters</p>

图片进阶——热区的设置
目的:点击图像的不同位置,跳转至不同的界面
原理:坐标(以图片的右上角为坐标原点,向右为x轴,向下y轴,单位为像素,可以用ps测量)
shape=react/circle/poly/
circle | 圆形(需要圆心的横坐标,纵坐标和圆的半径) |
react | 矩形(需要对角顶点的横坐标,纵坐标) |
poly | 多边形(可以有任意多个顶点,依次输入每个顶点的横纵坐标即可) |
