<p>由于要照顾到不同的浏览器下保持完美的显示效果，经常用到 CSS Hack，<span class='wp_keywordlink_affiliate'><a href="http://www.yzznl.cn/about" title="园子" rel="nofollow">园子</a></span>把常用的一些做了一下汇总，希望能够帮助到朋友们。<br />
<span id="more-40126"></span></p>
<h4>区别于IE6、IE7、Firefox 的 CSS Hack</h4>

<div class="wp_syntax"><table><tr><td class="line_numbers"><pre>1
2
3
</pre></td><td class="code"><pre class="css" style="font-family:Microsoft YaHei,Arial;"><span style="color: #6666ff;">.box</span> <span style="color: #00AA00;">&#123;</span><span style="color: #000000; font-weight: bold;">margin-top</span><span style="color: #00AA00;">:</span><span style="color: #933;">5px</span><span style="color: #00AA00;">;</span><span style="color: #00AA00;">&#125;</span> <span style="color: #808080; font-style: italic;">/*Firefox */</span>
<span style="color: #00AA00;">*</span> html <span style="color: #6666ff;">.box</span> <span style="color: #00AA00;">&#123;</span><span style="color: #000000; font-weight: bold;">margin-top</span><span style="color: #00AA00;">:</span><span style="color: #933;">10px</span><span style="color: #00AA00;">;</span><span style="color: #00AA00;">&#125;</span> <span style="color: #808080; font-style: italic;">/*IE6*/</span>
<span style="color: #00AA00;">*+</span>html <span style="color: #6666ff;">.box</span> <span style="color: #00AA00;">&#123;</span><span style="color: #000000; font-weight: bold;">margin-top</span><span style="color: #00AA00;">:</span><span style="color: #933;">15px</span><span style="color: #00AA00;">;</span><span style="color: #00AA00;">&#125;</span> <span style="color: #808080; font-style: italic;">/*IE7*/</span></pre></td></tr></table></div>

<p>通过上述 CSS Hack 可以实现在 Firefox 中上边距为5px, IE6 中上边距为10px, IE7 上边距为15px。</p>
<h4>屏蔽IE浏览器（也就是IE下不显示）</h4>

<div class="wp_syntax"><table><tr><td class="line_numbers"><pre>1
2
</pre></td><td class="code"><pre class="css" style="font-family:Microsoft YaHei,Arial;"><span style="color: #00AA00;">*:</span>lang<span style="color: #00AA00;">&#40;</span>zh<span style="color: #00AA00;">&#41;</span> select <span style="color: #00AA00;">&#123;</span><span style="color: #000000; font-weight: bold;">font</span><span style="color: #00AA00;">:</span><span style="color: #933;">12px</span>  !important<span style="color: #00AA00;">;</span><span style="color: #00AA00;">&#125;</span> <span style="color: #808080; font-style: italic;">/*FF可见*/</span>
select<span style="color: #3333ff;">:empty </span><span style="color: #00AA00;">&#123;</span><span style="color: #000000; font-weight: bold;">font</span><span style="color: #00AA00;">:</span><span style="color: #933;">12px</span>  !important<span style="color: #00AA00;">;</span><span style="color: #00AA00;">&#125;</span> <span style="color: #808080; font-style: italic;">/*safari可见*/</span></pre></td></tr></table></div>

<p>这里select是选择符，根据情况更换。第二句是MAC上safari浏览器独有的。</p>
<h4>IE6及IE6以下识别</h4>

<div class="wp_syntax"><table><tr><td class="line_numbers"><pre>1
</pre></td><td class="code"><pre class="css" style="font-family:Microsoft YaHei,Arial;"><span style="color: #00AA00;">*</span> html  select <span style="color: #00AA00;">&#123;</span>…<span style="color: #00AA00;">&#125;</span></pre></td></tr></table></div>

<p>这个地方要特别注意很多博客都写成了是IE6的HACK其实IE5.x同样可以识别这个HACK。其它浏览器不识别。</p>

<div class="wp_syntax"><table><tr><td class="line_numbers"><pre>1
</pre></td><td class="code"><pre class="css" style="font-family:Microsoft YaHei,Arial;">html<span style="color: #808080; font-style: italic;">/**/</span> <span style="color: #00AA00;">&gt;</span>body  select <span style="color: #00AA00;">&#123;</span>…<span style="color: #00AA00;">&#125;</span></pre></td></tr></table></div>

<p>这句与上一句的作用相同。</p>
<h4>仅IE6不识别，屏蔽IE6</h4>

<div class="wp_syntax"><table><tr><td class="line_numbers"><pre>1
</pre></td><td class="code"><pre class="css" style="font-family:Microsoft YaHei,Arial;">select <span style="color: #00AA00;">&#123;</span> <span style="color: #000000; font-weight: bold;">display</span> <span style="color: #00AA00;">:</span><span style="color: #993333;">none</span><span style="color: #00AA00;">;</span> <span style="color: #808080; font-style: italic;">/*屏蔽IE6*/</span><span style="color: #00AA00;">&#125;</span></pre></td></tr></table></div>

<p>这里主要是通过CSS注释分开一个属性与值，注释在冒号前。</p>
<h4>仅IE7与IE5.0可以识别</h4>

<div class="wp_syntax"><table><tr><td class="line_numbers"><pre>1
</pre></td><td class="code"><pre class="css" style="font-family:Microsoft YaHei,Arial;"><span style="color: #00AA00;">*+</span>html  select <span style="color: #00AA00;">&#123;</span>…<span style="color: #00AA00;">&#125;</span></pre></td></tr></table></div>

<p>当面临需要只针对IE7与IE5.0做样式的时候就可以采用这个HACK。</p>
<h4>仅IE7可以识别</h4>

<div class="wp_syntax"><table><tr><td class="line_numbers"><pre>1
</pre></td><td class="code"><pre class="css" style="font-family:Microsoft YaHei,Arial;"><span style="color: #00AA00;">*+</span>html  select <span style="color: #00AA00;">&#123;</span>…!important<span style="color: #00AA00;">;</span><span style="color: #00AA00;">&#125;</span></pre></td></tr></table></div>

<p>当面临需要只针对IE7做样式的时候就可以采用这个HACK。</p>
<h4>仅IE6与IE5不识别，屏蔽IE6与IE5</h4>

<div class="wp_syntax"><table><tr><td class="line_numbers"><pre>1
</pre></td><td class="code"><pre class="css" style="font-family:Microsoft YaHei,Arial;">select<span style="color: #808080; font-style: italic;">/**/</span> <span style="color: #00AA00;">&#123;</span><span style="color: #000000; font-weight: bold;">display</span> <span style="color: #00AA00;">:</span><span style="color: #993333;">none</span><span style="color: #00AA00;">;</span><span style="color: #00AA00;">&#125;</span> <span style="color: #808080; font-style: italic;">/*IE6,IE5不识别*/</span></pre></td></tr></table></div>

<p>这里与上面一句不同的是在选择符与花括号之间多了一个CSS注释。<strong>不屏蔽IE5.5 。</strong></p>
<h4>仅IE5不识别，屏蔽IE5</h4>

<div class="wp_syntax"><table><tr><td class="line_numbers"><pre>1
</pre></td><td class="code"><pre class="css" style="font-family:Microsoft YaHei,Arial;">select <span style="color: #00AA00;">&#123;</span>…<span style="color: #00AA00;">&#125;</span> <span style="color: #808080; font-style: italic;">/*IE5不识别*/</span></pre></td></tr></table></div>

<p>这一句是在上一句中去掉了属性区的注释。只有IE5不识别，IE5.5可以识别。	</p>
<h4>盒模型解决方法</h4>

<div class="wp_syntax"><table><tr><td class="line_numbers"><pre>1
</pre></td><td class="code"><pre class="css" style="font-family:Microsoft YaHei,Arial;">selct <span style="color: #00AA00;">&#123;</span><span style="color: #000000; font-weight: bold;">width</span><span style="color: #3333ff;">:IE5</span>.x宽度<span style="color: #00AA00;">;</span> <span style="color: #000000; font-weight: bold;">voice-family</span> <span style="color: #00AA00;">:</span>”\”<span style="color: #00AA00;">&#125;</span>\”<span style="color: #ff0000;">&quot;; voice-family:inherit; width:正确宽度;}</span></pre></td></tr></table></div>

<p>盒模型的清除方法不是通过!important来处理的。这点要明确。	</p>
<h4>只有Opera识别</h4>

<div class="wp_syntax"><table><tr><td class="line_numbers"><pre>1
</pre></td><td class="code"><pre class="css" style="font-family:Microsoft YaHei,Arial;"><span style="color: #a1a100;">@media all and (min-width: 0px){ select {……} }</span></pre></td></tr></table></div>

<p>针对Opera浏览器做单独的设定。	</p>
<h4>IE的if条件Hack</h4>
<pre>
<!–[if IE]> Only IE <![endif]–>
所有的IE可识别
<!–[if IE 5.0]> Only IE 5.0 <![endif]–>
只有IE5.0可以识别
<!–[if gt IE 5.0]> Only IE 5.0+ <![endif]–>
IE5.0包换IE5.5都可以识别
<!–[if lt IE 6]> Only IE 6- <![endif]–>
仅IE6可识别
<!–[if gte IE 6]> Only IE 6/+ <![endif]–>
IE6以及IE6以下的IE5.x都可识别
<!–[if lte IE 7]> Only IE 7/- <![endif]–>
仅IE7可识别
</pre>
<h4>清除浮动</h4>

<div class="wp_syntax"><table><tr><td class="line_numbers"><pre>1
</pre></td><td class="code"><pre class="css" style="font-family:Microsoft YaHei,Arial;">select<span style="color: #3333ff;">:after </span><span style="color: #00AA00;">&#123;</span><span style="color: #000000; font-weight: bold;">content</span><span style="color: #00AA00;">:</span>”.”<span style="color: #00AA00;">;</span> <span style="color: #000000; font-weight: bold;">display</span><span style="color: #00AA00;">:</span><span style="color: #993333;">block</span><span style="color: #00AA00;">;</span> <span style="color: #000000; font-weight: bold;">height</span><span style="color: #00AA00;">:</span><span style="color: #cc66cc;">0</span><span style="color: #00AA00;">;</span> <span style="color: #000000; font-weight: bold;">clear</span><span style="color: #00AA00;">:</span><span style="color: #993333;">both</span><span style="color: #00AA00;">;</span> <span style="color: #000000; font-weight: bold;">visibility</span><span style="color: #00AA00;">:</span><span style="color: #993333;">hidden</span><span style="color: #00AA00;">;</span><span style="color: #00AA00;">&#125;</span></pre></td></tr></table></div>

<p>在Firefox中，当子级都为浮动时，那么父级的高度就无法完全的包住整个子级，那么这时用这个清除浮动的HACK来对父级做一次定义，那么就可以解决这个问题。	</p>
<h4>截字省略号</h4>

<div class="wp_syntax"><table><tr><td class="line_numbers"><pre>1
</pre></td><td class="code"><pre class="css" style="font-family:Microsoft YaHei,Arial;">select <span style="color: #00AA00;">&#123;</span> -o-text-<span style="color: #000000; font-weight: bold;">overflow</span><span style="color: #00AA00;">:</span>ellipsis<span style="color: #00AA00;">;</span> text-<span style="color: #000000; font-weight: bold;">overflow</span><span style="color: #00AA00;">:</span>ellipsis<span style="color: #00AA00;">;</span> <span style="color: #000000; font-weight: bold;">white-space</span><span style="color: #00AA00;">:</span><span style="color: #993333;">nowrap</span><span style="color: #00AA00;">;</span> <span style="color: #000000; font-weight: bold;">overflow</span><span style="color: #00AA00;">:</span><span style="color: #993333;">hidden</span><span style="color: #00AA00;">;</span> <span style="color: #00AA00;">&#125;</span></pre></td></tr></table></div>

<p>这个是在越出长度后会自行的截掉多出部分的文字，并以省略号结尾，很好的一个技术。只是目前Firefox并不支持。</p>

<span id="more-36918"></span></p>
<p><strong>id的使用原则</strong></p>
<p>先来说说id，id具有<strong>唯一性</strong>，其使用原则也是依据这一特性建立的。id是不能重复的，所以在<span class='wp_keywordlink_affiliate'><a href="http://www.yzznl.cn/category/xhtml" title="xhtml">xhtml</a></span>的结构中，大结构一定是用id。比如标志、导航、主体内容、版权。这些根据制定的规范命名为#logo , #nav , #content , #copyright 等等，本着其唯一性的原则园子建议定义id尽量在外围使用。</p>
<p><strong>class的使用原则<br />
</strong>class在CSS的定义中具有<strong>普遍性</strong>。说白一点就是class具有可重复无限制的使用多次，园子建议大家尽量在结构内部使用。这样做的好处是有利于网站代码的后期维护与修改，这样的做法就会让所有的class都成为id的子级或是孙级。在我们写CSS的时候可以写成这样 #father .child  {…}，另外需要注意的是尽量不要让class包含id，比如.father #child  {…}如果写成这样很显然就非常不可取。当然这也只是相对于良好书写习惯的一些建议，仅供大家参考。</p>
<p>综上所述，归总起来一句话：<strong>id是唯一的并且是父级的，class是可以重复的并且是子级的</strong>。保持一个良好的代码书写习惯对于以后的代码维护会有很大的帮助，如果您有更好的建议，欢迎给我留言探讨。</p>

<p>尽管上图显得有点复杂，不过它展示了每个HTML元素是如何被盒子所围绕的。我们可以通过CSS来调整这些盒子。通过这些图例相信你对CSS盒模型会有个大致的理解，在后续的文章中<span class='wp_keywordlink_affiliate'><a href="http://www.yzznl.cn/about" title="园子" rel="nofollow">园子</a></span>将会介绍更多关于CSS方面的知识。</p>

			<content:encoded><![CDATA[<p>尽管现在的网络质量日新月异的发展着，但做为网页设计者还是非常在意网站的交互速度。我们都知道，Web网站可用性的关键指标是速度，更确切地说，是页面能以多快的速度出现在访问者的浏览器窗口里。我们力求努力做到让自己的网站速度更快一些，常常要做的是去优化站点里每一个图像文件，但是你知道吗，<span class='wp_keywordlink_affiliate'><a href="http://www.yzznl.cn/category/css" title="css">css</a></span>文件也是需要优化的。<span class='wp_keywordlink_affiliate'><a href="http://www.yzznl.cn/about" title="园子" rel="nofollow">园子</a></span>在做一个企业站点时把优化过的CSS和之前用Dreamweaver自动生成的CSS做了下对比，结果竟然发现文件大小缩减了35%！</p>
<p>其实优化CSS文件非常简单，只要我们在网站完成之后把CSS文件做下规整，注意下一些比较常用的缩写方法，你也可以让你的CSS文件做到真正的优化。<br />
<span id="more-35673"></span></p>
<p><strong>当属性值为0时</strong><br />
书写原则是如果CSS属性值为0，那么你不必为其添加单位(如:px/em)，你可能会这样写:<br />
<span style="color: #0099cc;">padding: 10px 5px 0px 0px;</span></p>
<p>试试这样吧:<br />
<span style="color: #0099cc;">padding: 10px 5px 0 0;</span></p>
<p><strong>移除选择器</strong><br />
选择器是你在为一些元素应用CSS样式时的基本方法，比如h1, h2, h2, div, strong, pre, ul, ol等等…如果你使用了class(.类名)或ID(#id名),那么就不用再在声明CSS时包含选择器了。</p>
<p><span style="color: #0099cc;">div#logowrap</span></p>
<p>尝试扔掉多余的选择器吧:<br />
<span style="color: #0099cc;">#logowrap</span></p>
<p>在这个例子中所谓的那个选择器就是div</p>
<p><strong>学会使用万能通配符*<br />
</strong>要明智的使用*而避免它在整个CSS样式表中乱开玩笑，*是个通配符，你可以使用它来为你的设计部分或全部进行一系列CSS声明。例如:</p>
<p><span style="color: #0099cc;">* {<br />
margin: 0;<br />
}</span></p>
<p>这个声明会将所有元素的margin值设置为0，同样的，为了严谨起见，你可以尝试这样设置:<br />
<span style="color: #0099cc;">#menu * {<br />
margin: 0;<br />
}</span></p>
<p>这样的声明是指将#menu下的所有元素的margin设为0。</p>
<p><strong>背景的缩写方法</strong><br />
背景(background)属性可能会包含设置背景色、背景图、背景图的位置和背景图重复方式的参数，你可能会写成:<br />
<span style="color: #0099cc;">background-image: url(”logo.png”);<br />
background-position: top center;<br />
background-repeat: no-repeat;</span></p>
<p>其实可以缩写成:<br />
<span style="color: #0099cc;">background: url(logo.png) no-repeat top center;</span></p>
<p><strong>颜色</strong><br />
颜色(color)属性在CSS通常指定为一个十六进制的值,一个#加6位数字，他的简写方式是如果颜色值由成对儿出现的三对而数字组成，你可以省略掉没对中的一个数字。</p>
<p><span style="color: #0099cc;">#000000 可以写成 #000, #336699 可以写成 #369</span></p>
<p>这种简写技巧只适用于成对出现的颜色值（即奇数位色值和偶数位色值相同时），其它颜色值不适用这种技巧，比如:<br />
<span style="color: #0099cc;">#010101, #223345, #FFF000</span></p>
<p><strong>Margin(外边距/空白边)的缩写</strong><br />
声明CSS magin值得时候通常会写成这样:<br />
<span style="color: #0099cc;">margin-top:0px;<br />
margin-right:10px;<br />
margin-bottom:0px;<br />
margin-left:10px;</span></p>
<p>让我们试试把值为0的单位去掉，并把4条声明合并成一条声明:<br />
<span style="color: #0099cc;">margin:0 10px 0 10px;</span></p>
<p>当你声名padding、margin、border(还有一些其他属性)时，记得要把按照顺时针的方向来声明属性值，也就是按照上-右-下-左的方向。关于这些属性还有另一个更加简单的写法，看看属性中上和下、左和右是否值是相等的，如果是那么就可以进一步优化了，你可以省略掉后两个值，剩下的两个值前者指上下，后者指左右:<br />
<span style="color: #0099cc;">margin:0 10px;</span></p>
<p>它是指左右的值为10px，上下的值为0；Padding(内边距)padding的简写技巧等同于margin:</p>
<p><span style="color: #0099cc;">padding-top:0px;<br />
padding-right:10px;<br />
padding-bottom:0px;<br />
padding-left:10px;</span></p>
<p>可以写成:<br />
<span style="color: #0099cc;">padding: 0 10px;</span></p>
<p><strong>Border(边框)边框的缩写</strong><br />
border缩写的方式相比其它声明来说会比较复杂，很多CSSer一开始都容易记混它的简写顺序，如果你想声明一个1像素宽的实线黑色边框，可能会写成:<br />
<span style="color: #0099cc;">border-width:1px;<br />
border-style:solid;<br />
border-color:#000;</span></p>
<p>其实可以写成:<br />
<span style="color: #0099cc;">border:1px solid #000;</span></p>
<p>注意:这里的颜色值已经使用了上面讲过的颜色简写方法了哦。我们还可以为四个边设置不同的宽度:<br />
<span style="color: #0099cc;">border-top-width:1px;<br />
border-right-width:2px;<br />
border-bottom-width:3px;<br />
border-left-width:4px;</span></p>
<p>可以简写成:<br />
<span style="color: #0099cc;">border-width:1px 2px 3px 4px;</span></p>
<p>最后，我们还可以只设置右和下边框的样式:<br />
<span style="color: #0099cc;">border-right:1px solid #000;<br />
border-bottom:1px solid #000;</span></p>
<p>虽然并没减少多少代码,但园子建议写成这样:<br />
<span style="color: #0099cc;">border:1px solid #000;<br />
border-width:0 1px 1px 0;</span></p>
<p>先设置四个边的默认风格，然后声明具体的哪个边要显示。</p>
<p>文字属性的缩写<br />
文字属性也有很多可能会用到的属性值，像背景一样，你可能会声明这种复杂的文字样式:<br />
<span style="color: #0099cc;">font-style:italic;<br />
font-variant:small-caps;<br />
font-weight:bold;<br />
font-size:1em;<br />
line-height:150%;<br />
font-family:宋体, Arial, sans-serif;</span></p>
<p>其实可以优化成一行:<br />
<span style="color: #0099cc;">font:italic small-caps bold 1em/150% 宋体, Arial, sans-serif;</span></p>
<p>列表的缩写<br />
<span style="color: #0099cc;">list-style-type:square;<br />
list-style-position:inside;<br />
list-style-image:url(filename.gif);</span></p>
<p>可以写成:<br />
<span style="color: #0099cc;">list-style:square inside url(filename.gif);</span></p>
<p>再给大家举个综合的例子，请看下面的CSS代码：<br />
<span style="color: #0099cc;">.sample1 {<br />
margin-top: 15px;<br />
margin-right: 20px;<br />
margin-bottom: 12px;<br />
margin-left: 24px;<br />
padding-top: 5px;<br />
padding-right: 10px;<br />
padding-bottom: 4px;<br />
padding-left: 8px;<br />
border-top-width: thin;<br />
border-top-style: solid;<br />
border-top-color: #000000;<br />
}</span></p>
<p>将它用一些缩写性质来替代就能够把代码减少为下面这样，两者的实际效果是完全一样的：<br />
<span style="color: #0099cc;">.sample1 {<br />
margin: 15px 20px 12px 24px;<br />
padding: 5px 10px 4px 8px;<br />
border-top: thin solid #000;<br />
}</span></p>
<p><strong>下面是CSS缩写性质的列表以及它们所表示的常规性质。</strong></p>
<ul>
<li>Background（背景）：背景附件、背景颜色、背景图像、背景位置、背景重复</li>
<li>Border（边框）：边框颜色、边框风格、边框宽度</li>
<li>border-bottom（底部边框）：底部边框颜色、底部边框样式、底部边框宽度</li>
<li>border-left（左侧边框）：左侧边框颜色、左侧边框样式、左侧边框宽度</li>
<li>border-right（右侧边框）：右侧边框颜色、右侧边框样式、右侧边框宽度</li>
<li>border-top（顶部边框）：顶部边框颜色、顶部边框样式、顶部边框宽度</li>
<li>cue（声音提示）：前提示、后提示</li>
<li>font（字体）：字体、字号、字体样式、字体粗细、字体变体、线高度、字体大小调整、字体拉伸</li>
<li>list-style（列表样式）：列表样式图像、列表样式位置、列表样式类型</li>
<li>margin（空白）：顶部空白、右侧空白、底部空白、左侧空白</li>
<li>outline（大纲）：大纲颜色、大纲样式、大纲宽度</li>
<li>padding（间隙）：顶部间隙、右侧间隙、底部间隙、左侧间隙</li>
<li>pause（暂停）：后暂停、前暂停</li>
</ul>
<p>总结了这么多，园子相信只要你留意正确的缩写方法，你也可以在最短的时间内把你的CSS优化好。赶快尝试一下吧。</p>
