# 标题 Header 不光是 Header。你知道 UI 一般很喜欢在 Header 旁边弄一个带颜色的竖条(确实,光有文字太单调了)。所以这它可以有个条。 ```html <div style="padding-left: 24px; position: relative;"> <div style=" position: absolute; left: 0; top: 0; bottom: 0; width: 24px; background-color: rgba(128, 128, 128, .5); "></div> <n-h1><n-text type="primary">sin(x)</n-text></n-h1> <n-h1 prefix="bar"><n-text type="primary">sin(x)</n-text></n-h1> <n-h1 prefix="bar" align-text><n-text type="primary">sin(x)</n-text></n-h1> <n-h1 prefix="bar" align-text type="success"><n-text type="success">sin(x)</n-text></n-h1> <n-h1 prefix="bar" align-text type="info"><n-text type="info">sin(x)</n-text></n-h1> <n-h1 prefix="bar" align-text type="warning"><n-text type="warning">sin(x)</n-text></n-h1> <n-h1 prefix="bar" align-text type="error"><n-text type="error">sin(x)</n-text></n-h1> <n-h2>cos(x)</n-h2> <n-h2 prefix="bar">cos(x)</n-h2> <n-h2 prefix="bar" align-text>cos(x)</n-h2> <n-h3>-sin(x)</n-h3> <n-h3 prefix="bar">-sin(x)</n-h3> <n-h3 prefix="bar" align-text>-sin(x)</n-h3> <n-h4>-cos(x)</n-h4> <n-h4 prefix="bar">-cos(x)</n-h4> <n-h4 prefix="bar" align-text>-cos(x)</n-h4> <n-h5>sin(x)</n-h5> <n-h5 prefix="bar">sin(x)</n-h5> <n-h5 prefix="bar" align-text>sin(x)</n-h5> <n-h6>循环啊!</n-h6> <n-h6 prefix="bar">循环啊!</n-h6> <n-h6 prefix="bar" align-text>循环啊!</n-h6> </div> ```
