深入理解 vertical-align
关于vertical-align属性的值
- inherit： 继承
- 线类： 可选baseline （默认属性值），top，middle，bottom
- 文本类： text-top，text-bottom （文本上下边缘）
- 上标下标类： sub，super
- 数值百分比类： 20px，2em，20% …（支持负值）
vertical-align的数值百分比类型的值
- 数值的含义：在baseline对齐基础上上下偏移对应的数值大小，比如值为1px就是在默认（baseline）基础上上移1像素，1em就是上移一个字体大小。
- 然而对于百分比来说，它是相对于line-height来计算的。
比如指定line-height：30px；vertical-align：-10%；那么实际上vertical-align的值就是-3px，也就是在基线对齐的基础上，下移3px。
适用情况
只适用于inline，inline-block，table-cell （td标签）元素
所以对p标签或是div等元素设置此属性，不会有任何作用。 （当然，除非你修改了display属性）
既然如此，我们就可以利用这种情况处理一些特殊情况。比如一个块级元素中有一个img元素，img元素会因为其默认vertical-align属性以及隐匿元素的存在而导致下方有空隙，那么解决的办法之一就是将img元素块状化。
*（上面谈到的情况，除了块状化之外，还有方法如下：
1. 将img元素的vertical-align属性变为bottom，即img元素与隐匿元素的底边对齐，或是middle，即中线对齐，或是top。
2. 改变line-height
关于vertical-align的middle值
定义：inline/inline-block元素：元素的垂直中心点和父元素基线上1/2x-height处 （就是说元素和后面隐匿的x字符中心点对齐）
这么来说的话，当对图片设置middle属性时，其与后面的隐匿x中心线对齐了，又因为容器的高度是line-height撑开的，如果将lin-height设置为0，那么line-height将作为一条线横亘在x所占内容区域的中间；所以当line-height不为0的时候，其中心线也在x所占内容区域的中间。然而x字符的中间，与其所在内容区域的中间，并不是重叠的！（要看字体类型）所以，设置middle的图片的中线并没有精确的与容器的中线重叠！ （内容区域可理解为鼠标滑动选中该字符的蓝色背景区域）
关于vertical-align的文本类值
text-top：盒子的顶部和父级content area的顶部对齐
text-bottom：盒子的底部和父级content area的底部对齐
还有两点需要注意：
1. 使用该属性后，vertical-align的效果与元素前后的其他元素没有任何关系
2. 此属性作用时候与line-height没有任何关系，只与font-size相关
综上：至少两个可以使用vertical-align的地方：
1. 小图标和文字对齐（使用负的数值）
2. 使图片或是多行文字居中
视频中说使图片居中的方式：
1. 使图片或是多行文字inline-block化
2. 在元素后跟一个height为100%空i标签元素
3. 元素和i元素都使用vertical-align:middle
本次问题
- 行高会改变基线的位置吗？

<p>看到上面这个奇怪的现象了吗，之所以会这样是因为：<span style="color: #f00">一个inline-block元素，如果里面没有内容，那么其基线就是其底边缘；否则其基线就是最后一个元素的基线。span>第一个方块的基线是底边，第二个方块的基线则是内部元素的基线，也就是x字母的底部，两者对齐！！p>

<p>当我们把第二个元素的行高设置为0后，出现了这样的情况！<span style="color: #f00;"> 是因为行高为0后，该内容区域的高度就变成了0，实际高度即为0。又因为行高能让字符居中，其为0后也就出现在了内容区域的中间。span>这样一来，字符出现在框外也就不足为奇了！又因为上面的解释，这第二个框的基线仍然是内其中字符的基线，所以整体情况变成如此。p>

<p>vertical-align的值为text-top时，可以发现图片的顶线和父级元素内容区域（学习line-height时了解到，内容区域的高度只与font-size相关），所以由于我们给div设置了32像素大小的字体，那么其必然是和32像素的字体的内容区域的顶部对齐！p>
