如何在ITCSS项目中包含外部库？

问题描述：

//******** ITCSS layers :: https://www.xfive.co/blog/itcss-scalable-maintainable-css-architecture/ 
//** 1. Settings – used with preprocessors and contain font, colors definitions, etc. 
//** 2. Tools – globally used mixins and functions. It’s important not to output any CSS in the first 2 layers. 

//** 3. Generic – reset and/or normalize styles, box-sizing definition, etc. This is the first layer which generates actual CSS. 
//** 4. Elements – styling for bare HTML elements (like H1, A, etc.). These come with default styling from the browser so we can redefine them here. 
//** 5. Objects – class-based selectors which define undecorated design patterns, for example media object known from OOCSS 
//** 6. Components – specific UI components. This is where majority of our work takes place and our UI components are often composed of Objects and Components 
//** 7. Trumps – utilities and helper classes with ability to override anything which goes before in the triangle, eg. hide helper class 
//******** 

// Settings 
@import "settings/settings.global"; 

// Tools 
@import "tools/tools.extend"; 
@import "tools/tools.mixin"; 

// Elements 
@import "elements/elements.page"; 

// Components 
@import "components/components.overlay"; 
@import "components/components.slice"; 
@import "components/components.text"; 

// Trumps 
@import "trumps/trumps.utilities";

里面我的index.html，包括我的main.css并通过凉亭或NPM，其他外部库，如正常化，引导电网或animate.css 。导入其他库的正确方法是什么？在main.scss之前，之后或内部？我有这个疑问，因为重要的是不要在前2层输出任何CSS。此外，通常这个文件是纯CSS，我不能@import在我的* .scss里面。

感谢

<head> 
    <!--build:css css/main.min.css --> 
    <link rel="stylesheet" href="bower_components/normalize-css/normalize.css"> 
    <link rel="stylesheet" href="bower_components/bootstrap-v3-grid/bootstrap-v3-grid.css"> 
    <link rel="stylesheet" href="style/css/main.css"> 
    <!-- endbuild --> 
</head>

答

我想符号链接Normalize.css到萨斯文件（_generic.normalize.scss），并将其导入通用层。

我将符号链接Bootstrap到一个Sass文件（_objects.grid.scss）并将其导入到Objects层。

这将保持ITCSS顺序为真，并将渲染阻塞CSS减少为仅一个HTTP请求。

感谢您的回复，Harry！ –
