最近在看HeadFirstHTML与CSS，虽然是小白书，但是我对于前端并没有系统的学习过，都是用到了再看，所以掌握的不是很好。
因此想补充自己前端的知识。
关于这本书的学习笔记我只写这一篇(接下来继续看HTML5及JS的相关知识)
代码素材地址:https://github.com/youaresherlock/headfirstHtmlAndCSS
HTML5 DOM 为 <audio> 和 <video> 元素提供了方法、属性和事件。
这些方法、属性和事件允许您使用 JavaScript 来操作 <audio> 和 <video> 元素。

<h1>Starbuzz meets social media</h1>
<time datatime="2012-03-12">3/12/2012</time>
</header>
<p>
Here at Starbuzz we're embracing the social media craze.
In fact, we're going further than any of our competitors and
we're very close to announcing a revolutionary new product that
links your coffee drinking directly to your social
network. Forget "checking in"; we're going way beyond that, and
with this new product every sip of smooth, aromatic, hot Starbuzz
blend is going to to be shared with your social network.
</p>
<p>
Sound like science fiction? It's not; I'm already
testing our final prototype social network cup as I write this,
which links you, the drinker, right to your favorite social
networks. We've made a huge investment to make this happen
and we've created a reusable coffee cup complete with RFID,
NFC, Bluetooth, and Wifi (not to mention a few more things the tech
folks know about, because hey, I'm just the coffee guy).
</p>
<p>
So, keep your eyes out for this amazing new cup. And I'll
be releasing a video teaser soon to tell you all about this
new invention, straight from Starbuzz Coffee.

<h1>Starbuzz uses computer science</h1>
<time datetime="2012-03-10">3/10/2012</time>
</header>
<p>
Have you ever noticed how efficient a Starbuzz Coffee
house is? The lines alway move fast, and despite the
astronomical number of different drinks any customer can
order, we have your drink up, hot (or cold if that's the
way you want it) and ready in seconds. How do we do it?
</p>
<p>
To pull this off, we take advantage of the latest and
greatest in computer science. In fact, we train
our staff to be one big distributed computer. The cashiers
create the orders for the distributed computer, complete
with your name and the drinks special instructions. Then
our specialized drink makers grab the next cup
and go about working on your order until it's finished.
</p>
<p>
With this design, we are able to horizontally scale our operation
any time we want. All we need to do is add more cashiers
and drink makers (not to mention a fair amount of support
staff you never see) as the customer flow grows.

<h1>Most unique patron of the month</h1>
<time datetime="2012-02-18">2/18/2012</time>
</header>
<p>
Our most unique patron of the month award goes to a
customer in Poulsbo, Washington, whose daily morning order
is a "six-splenda, no-foam, 130-degree non-fat-soy latte,
with the splenda stirred in before the milk is added." Do we
have unique customers or what?

Why wait? You can order all our fine coffees right from the Internet with our new,

enter your order, and behind the scenes, your coffee is roasted, ground
(if you want), packaged, and shipped to your door.
