行高
行高的构成
- 是lineBox的高度
- lineBox的高度是由其内部inlineBox的高度而决定的
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>inline</title> <style> span{ background:red; } .c1{ line-height: 20px; } .c2{ line-height: 8px; } .c3{ line-height: 30px; } .c5{ line-height: 28px; } </style> </head> <body> <div> <span class="c1">inline box xfg中文</span> <span class="c2">inline box</span> <span class="c3">inline box</span> inline box <span class="c5">inline box</span> </div> </body> </html>上面的例子中，每个line-height都不一样，但是用浏览器打开之后，发现显示的行高都是一样的。这是由于其外部的形成的lineBox统一决定的，lineBox的行高是由其内部最大的行高决定的。30px
行高相关的现象和方案
- 不同的字体大小在一行中，是根据baseline来对齐的。
- 可以使用vertical-align来设置对齐方式
- 经典问题：文字和图片在一行中，会发现图片出现与下底线之间存在空隙的问题，就是因为图片同文字使用默认的baseline对齐导致的，可以通过设置图片的vertical-align:bottom来解决
背景
- 背景颜色
- 渐变色背景
- 多背景叠加

- 图片直接使用base64格式，只适用于小图标
- 多分辨率适配
