    ActivereportsJS是纯前端的报表控件，可以跟任何web项目项目进行集成，集成的时候就会存在样式主题UI不一致的情况，这时候就需要通过调整CSS或者其他方式实现样式统一。ActivereportsJS提供一个主题编辑器的能力，可以轻松实现UI样式的匹配。

    下面我就带大家一起动手操作下

    1、首先，打开主题编辑器：Theme Generator

    2、进行主题颜色的设置，可以自定义设置主题颜色，字体大小、字体类型

    3、预览看是不期待的结果，然后点击下载对应的CSS文件

    4、下载后的CSS文件直接集成到报表项目中

    <link

      rel="stylesheet"

  type="text/css"

  href="styles/ar-js-theme/ar-js-ui.css"

/>

<link

  rel="stylesheet"

  type="text/css"

  href="styles/ar-js-theme/ar-js-viewer.css"

/>

<link

  rel="stylesheet"

  type="text/css"

  href="styles/ar-js-theme/ar-js-designer.css"

/>
