css 实现可调风速的少女系风扇

我正在参加「初夏创意投稿大赛」详情请看：初夏创意投稿大赛

前言

大家好，我是zz,太久没和大家见面啦。

思路

在淘宝找了个电风扇，本来想原封不动的按图片写,用代码实现可太难啦，后来实现了一个简化版的电风扇。

html结构

起初设计一个基本的框架结构

<div id="fan">
    <input type="radio" name="switch" class="switch_0"/>
    <div class="switch_btn_0">0</div>
    <input type="radio" checked name="switch" class="switch_1"/>
    <div class="switch_btn_1">1</div>
    <input type="radio" name="switch" class="switch_2"/>
    <div class="switch_btn_2">2</div>
	<input type="radio" name="switch" class="switch_3"/>
	<div class="switch_btn_3">3</div>
	<div class="mask">
            <div class="logo">CSS3 Fan</div>
            <div class="line_1"></div>
            <div class="line_2"></div>
            <div class="line_3"></div>
            <div class="line_4"></div>
            <div class="line_5"></div>
            <div class="line_6"></div>
            <div class="leafs">
                <div class="leaf_1"></div>
                <div class="leaf_2"></div>
                <div class="leaf_3"></div>
            </div>
	</div>
       <div class="header"></div>
	<div class="neck"></div>
	<div class="neck_footer"></div>
<div class="bottom"></div>
<div class="bottom_footer_1"></div>
<div class="bottom_footer_2"></div>
</div>

css结构

淘宝上找了很多的电风扇图片一点点修改，可花费工夫啦
