二.行内元素与块级元素有什么不同？</strong></p> <p><strong>1.</strong><strong>尺寸-块级元素和行内元素之间的一个重要的不同点</strong></p> <p><strong>行内元素和width</strong></p> <p>W3C CSS2 标准规定行内元素、非置换元素不会应用width属性。</p> <p>以下例子中，对行内元素应用了width:200px,你可以看到，根本就没有什么效果。</p> <p></p> <p><strong>行内元素和height</strong></p> <p>W3C CSS2 标准规定行内元素、非置换元素不会应用height属性，但是盒子高度可以通过line-height来指定。</p> <p>以下例子，对行内元素应用了height:50px,你可以看到什么效果都没。</p> <p></p> <p><strong>行内元素和padding</strong></p> <p>你可以给行内元素设置padding，但只有padding-left和padding-right生效。</p> <p>以下例子，行内元素应用了padding:50px。你可以看到对左右的内容有影响，但是对上下没影响。</p> <p></p> <p><strong>行内元素和marging</strong></p> <p>margin属性也是和padding属性一样，对行内元素左右有效，上下无效。</p> <p>下面的例子,对应用了margin:50px，你可以看到左右边缘是生效了但是内容上下却没有。</p> <p></p> <p>记住对行内元素</p> <p>设置宽度width 无效。<br />设置高度height 无效，可以通过line-height来设置。<br />设置margin 只有左右margin有效，上下无效。<br />设置padding 只有左右padding有效，上下则无效。注意元素范围是增大了，但是对元素周围的内容是没影响的，看图上效果就知道了</p> <p>上文部分翻译自：http://www.maxdesign.com.au/presentation/inline/</p> <p> </p> <p><strong>2.text-align属性是两者表现的又以不同之处</strong></p> <p> 在W3C CSS2.1规范第16.2节对text-align 有详细地描述：<br />------------------------------------------<br />值： left \| right \| center \| justify \| inherit<br />初始值：匿名值，由'direction'的值而定，如果'direction'为'ltr'则为'left'，如果'direction'为'rtl'则为'right'。<br />应用于: 块级元素，表格单元格，行内块元素<br />继承性: 是<br />计算后的值：初始值或指定值<br />------------------------------------------<br /><br /> 这个特性描述了如何使一个块元素的<strong>行内内容</strong>对齐。<br /> 注意一点，标准里说这个属性是用来对齐<strong>行内内容</strong>的，所以，<strong>不</strong>应该对块级内容起作用。<br /> 解释一下，<strong>行内内容</strong>是说由<strong>行内元素</strong>组成的内容，行内元素大家都知道吧，比如 SPAN 元素，IFRAME元素和元素样式的　‘display : inline’ 的都是行内元素；<strong>块级内容</strong>跟则是由块级元素构成，DIV 是最常用的块级元素。块级元素和行内元素的区别是，块级元素会占一行显示，而行内元素可以在一行并排显示。<br /> 这样，我们对这个特性的认识应该就清楚了。但是，问题来了，虽然标准里这么规定，那么是不是所有浏览器都遵守呢？答案是否定的。猜猜是哪个浏览器这么特立独行啊？ IE！！<br /> <strong>IE6/7及IE8混杂模式中，text- align:center可以使块级元素也居中对齐。其他浏览器中，text-align:center仅作用于行内内容上。</strong><br /> 解决这个问题比较好的方式，就是为所有需要相对父容器居中对齐的块级元素设置“margin-left:auto; margin-right:auto”。但这个方式 IE6/IE7/IE8的混杂模式中不支持，所以还要设置父容器的 "text-align:center;"。</p> <p> 若居中对齐的子元素内的行内内容不需要居中对齐，则还需要为其设置“text-align:left”： </div> <div class=""> <ul class="m-news-opt fix"> <li class="opt-item"> <a
