flex-stylus-class v0.1.6

flex-stylus-class

🍓classes of flex-stylus

使用stylus预处理器封装的flex布局类~ 只提供源码 业务项目自行构建

目标

• 简化常用布局✂️

• 解决一次又一次的布局兼容性问题😤ios >= 8 android >= 4.3

  

安装

    npm i flex-stylus-class --save-dev

or

    yarn add flex-stylus-class

使用

    // @file index.styl
    @import '~flex-stylus-class'

or

    // @file index.js
    import 'flex-stylus-class'

建议配置环境

• 建议使用webpack4构建工具
• 建议使用postcss-loader + autoprefixer + cssnano进行样式的兼容性、代码压缩处理

安装环境依赖

// install
yarn add postcss-loader autoprefixer cssnano

配置文件

// @file postcss.config.js
module.exports = {
    plugins: [
        require('autoprefixer'),
        require('cssnano')({
            preset: 'default'
        }),
    ]
};

// @file package.json browserslist
...,
"browserslist": [
    "iOS >= 8",
    "Android >= 4.3"
  ]

特别注意：browserslist中一定要写ios >= 8, 否则iphone5s (ios8.3）会出现布局错乱的兼容性问题。

普通flex布局

<section class=" c__flex">
<div class="item"></div>
<div class="item"></div>
<div class="item"></div>
<div class="item"></div>
<div class="item"></div>
</section>

等分flex

<div class="item"></div>
<div class="item"></div>
<div class="item"></div>
<div class="item"></div>
<div class="item"></div>

自动折行

<section class=" c__flex c__wrap">

    <div class="item"></div>
    <div class="item"></div>
    <div class="item"></div>

</section>

content居中

<section class=" c__flex c__center">
    <div class="item"></div>
    <div class="item"></div>
</section>

cbetween / caround 内容散列

// space-between 写法
<section class=" c__flex c__wrap c__between">
// space-around 写法
//  <section class=" c__flex c__wrap c__around">
    <div class="item"></div>
    <div class="item"></div>
    <div class="item"></div>
    <div class="item"></div>
    <div class="item"></div>
</section>

父元素和子元素配合

<section class="section-200 c__flex c__around">
    <div class="item"></div>
    <div class="item i__middle"></div>
    <div class="item i__bottom"></div>
</section>

垂直居中

<section class="c__vertical c__flex c__middle">
    <div class="item"></div>
    <div class="item"></div>
    <div class="item"></div>
    <div class="item"></div>
</section>

水平垂直居中

<section class="section-200 c__flex c__center c__middle">
    <div class="item"></div>
</section>

水平flex中嵌入垂直flex布局 水平方向等分

<section class="c__flex  c__flex-equal">
    <section class="c__flex c__vertical c__middle">
        <div class="item"></div>
        <div class="item"></div>
    </section>
    <div class="item"></div>
    <div class="item"></div>
</section>

垂直flex布局中嵌入水平flex布局

特别注意：ios10-已知的flex-direction:columnbug, 父元素为垂直flex布局时，子元素必须为display:block元素，所以要像下面这样，在水平flex元素外套一层block元素。

<section class="c__flex c__vertical c__middle">
    <div class="item"></div>
    <div class="item"></div>
    <div class="item"></div>
    <section>
        <div class="c__flex">
            <div class="item"></div>
            <div class="item"></div>
        </div>
    </section>
</section>
