CSS：
语法：–选择器{样式名:样式值；样式名:样式值; }–p {color:red; font-size:12px;}
行内样式：<pstyle="color:red;font-size:30px"></p>这种方式编写简单，定位准确。但是由直接将css代码写到了html标签的内部，导致结构与表现耦合，同时导致样式不能够复用，所以这种方式我们不使用。
内部样式表：
<style>
p{color:red; font-size :30px;}
<style>
这样使css独立于html代码，而且可以同时 多个元素设置样式，这是我们使用的比较多的一种方式。但是这种方式，样式只能在一个页面中使用，不能在多个页面中重复使用。
外部样式表:
<linkrel="stylesheet"type="text/css"
href="style.css">
这种方式将样式表放入到了页面的外部， 可以在多个页面中引入，同时浏览器加载文件时可以使用缓存，这是我们开发中使用的最多的方式

It's been a long day without you my friend
And I'll tell you all about it when I see you again
We've come a long way from where we began
Oh I'll tell you all about it when I see you again
When I see you again

cc'>Damn, who knew all the planes we flew
Good things we've been through
That I'll be standing right here
Talking to you about another path
I know we loved to hit the road and laugh
But something told me that it wouldn't last
Had to switch up look at things different see the bigger picture
Those were the days hard work forever pays
Now I see you win the better place
How could we not talk about family when family's all that we got?
Everything I went through you were standing there by my side
And now you gonna be with me for the last ride

First you both go out your way
And the vibe is feeling strong and what's small turn to a friendship
Turn into a bond and that bond will never be broken and the love will never get lost
And when brotherhood come first then the line
Will never be crossed established it on our own
When that line had to be drawn and that line is what
We reach so remember me when I'm gone
How could we not talk about family when family's all that we got?
Everything I went through you were standing there by my side
And now you gonna be with me for the last ride

So let the light guide your way
Hold every memory as you go
And every road you take will always lead you home
Hoo~
It's been a long day without you my friend
And I'll tell you all about it when I see you again
We've come a long way from where we began
Oh I'll tell you all about it when I see you again
When I see you again
When I see you again, see you again
When I see you again
