使用方法
安装
方法一：使用bower进行安装
bower install --save weui
方法二：使用npm进行安装
npm install --save weui
任选一种方法安装后，只需要在页面中引入 dist/style/weui.css 或者 dist/style/weui.min.css 其中之一即可。例如:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width,initial-scale=1,user-scalable=0">
<title>WeUI</title>
<link rel="stylesheet" href="path/to/weui/dist/style/weui.min.css"/>
</head>
<body>
</body>
</html>开发
git clone https://github.com/weui/weui.git cd weui npm install -g gulp npm install gulp -ws
运行 gulp -ws 命令，会监听 src 目录下所有文件的变更，并且默认会在8080端口启动服务器，然后在浏览器打开
http://localhost:8080/example。
元素类型
Button
按钮可以使用 a 或者 button 标签。wap 上要触发按钮的 active 态，必须触发 ontouchstart 事件，可以在
body 上加上 ontouchstart="" 全局触发。
按钮常见的操作场景：确定、取消、警示，分别对应 class：weui_btn_primary、weui_btn_default、weui_btn_warn，每种场景都有自己的置灰态
weui_btn_disabled，除此外还有一种镂空按钮 weui_btn_plain_xxx，客户端 webview 里的按钮尺寸有两类，默认宽度100%，小型按钮宽度自适应，两边边框与文本间距0.75em：
<a href="#" class="weui_btn weui_btn_primary">按钮</a>
<a href="#" class="weui_btn weui_btn_disabled weui_btn_primary">按钮</a>
<a href="#" class="weui_btn weui_btn_warn">确认</a>
<a href="#" class="weui_btn weui_btn_disabled weui_btn_warn">确认</a>
<a href="#" class="weui_btn weui_btn_default">按钮</a>
<a href="#" class="weui_btn weui_btn_disabled weui_btn_default">按钮</a>
<div class="button_sp_area">
<a href="#" class="weui_btn weui_btn_plain_default">按钮</a>
<a href="#" class="weui_btn weui_btn_plain_primary">按钮</a>
<a href="#" class="weui_btn weui_btn_mini weui_btn_primary">按钮</a>
<a href="#" class="weui_btn weui_btn_mini weui_btn_default">按钮</a>
</div>Cell
Cell，列表视图，用于将信息以列表的结构显示在页面上，是 wap 上最常用的内容结构。Cell 由多个 section 组成，每个 section 包括 section header
weui_cells_title以及 cells weui_cells。
Cell 由 thumbnail weui_cell_hd、body weui_cell_bd、accessory
weui_cell_ft 三部分组成，cell 采用自适应布局，在需要自适应的部分加上 class
weui_cell_primary即可：
带说明的列表项
<div class="weui_cells_title">带说明的列表项</div>
<div class="weui_cells">
<div class="weui_cell">
<div class="weui_cell_bd weui_cell_primary">
<p>标题文字</p>
</div>
<div class="weui_cell_ft">
说明文字
</div>
</div>
</div>
Cell 可根据需要进行各种自定义扩展，包括辅助说明、跳转、单选、复选等。下面以带图标、说明、跳转的列表项，其他情况可以直接参考
example 下的代码：
<div class="weui_cells_title">带图标、说明、跳转的列表项</div>
<div class="weui_cells weui_cells_access">
<a class="weui_cell" href="#">
<div class="weui_cell_hd">
<img src="" alt="icon" style="20px;margin-right:5px;display:block">
</div>
<div class="weui_cell_bd weui_cell_primary">
<p>cell standard</p>
</div>
<div class="weui_cell_ft">
说明文字
</div>
</a>
<a class="weui_cell" href="#">
<div class="weui_cell_hd">
<img src="" alt="icon" style="20px;margin-right:5px;display:block">
</div>
<div class="weui_cell_bd weui_cell_primary">
<p>cell standard</p>
</div>
<div class="weui_cell_ft">
说明文字
</div>
</a>
</div>
Dialog
若系统的 alert 窗体无法满足网页的临时视图内容需求，则可以自定义实现与 alert 形式相似的 dialog，并且在
dialog 中可以自定义地使用各种控件，来满足需求。
<div class="weui_dialog_confirm">
<div class="weui_mask"></div>
<div class="weui_dialog">
<div class="weui_dialog_hd"><strong class="weui_dialog_title">弹窗标题</strong></div>
<div class="weui_dialog_bd">自定义弹窗内容，居左对齐显示，告知需要确认的信息等</div>
<div class="weui_dialog_ft">
<a href="#" class="weui_btn_dialog default">取消</a>
<a href="#" class="weui_btn_dialog primary">确定</a>
</div>
</div>
</div>
<div class="weui_dialog_alert">
<div class="weui_mask"></div>
<div class="weui_dialog">
<div class="weui_dialog_hd"><strong class="weui_dialog_title">弹窗标题</strong></div>
<div class="weui_dialog_bd">弹窗内容，告知当前页面信息等</div>
<div class="weui_dialog_ft">
<a href="#" class="weui_btn_dialog primary">确定</a>
</div>
</div>
</div>
Progress
Progress 用于上传、下载等耗时并且需要显示进度的场景，用户可以随时中断该操作。
<div class="weui_progress">
<div class="weui_progress_bar">
<div class="weui_progress_inner_bar" style=" 50%;"></div>
</div>
<a href="#" class="weui_progress_opr">
<i class="weui_icon_cancel"></i>
</a>
</div>
Toast
Toast 用于临时显示某些信息，并且会在数秒后自动消失。这些信息通常是轻量级操作的成功、失败或等待状态信息。
<div id="toast" style="display: none;">
<div class="weui_mask_transparent"></div>
<div class="weui_toast">
<i class="weui_icon_toast"></i>
<p class="weui_toast_content">已完成</p>
</div>
</div>
<div id="loadingToast" class="weui_loading_toast" style="display:none;">
<div class="weui_mask_transparent"></div>
<div class="weui_toast">
<div class="weui_loading">
<!-- :) -->
<div class="weui_loading_leaf weui_loading_leaf_0"></div>
<div class="weui_loading_leaf weui_loading_leaf_1"></div>
<div class="weui_loading_leaf weui_loading_leaf_2"></div>
<div class="weui_loading_leaf weui_loading_leaf_3"></div>
<div class="weui_loading_leaf weui_loading_leaf_4"></div>
<div class="weui_loading_leaf weui_loading_leaf_5"></div>
<div class="weui_loading_leaf weui_loading_leaf_6"></div>
<div class="weui_loading_leaf weui_loading_leaf_7"></div>
<div class="weui_loading_leaf weui_loading_leaf_8"></div>
<div class="weui_loading_leaf weui_loading_leaf_9"></div>
<div class="weui_loading_leaf weui_loading_leaf_10"></div>
<div class="weui_loading_leaf weui_loading_leaf_11"></div>
</div>
<p class="weui_toast_content">数据加载中</p>
</div>
</div>
Msg Page
结果页通常来说可以认为进行一系列操作步骤后，作为流程结束的总结性页面。结果页的作用主要是告知用户操作处理结果以及必要的相关细节（可用于确认之前的操作是否有误）等信息；若该流程用于开启或关闭某些重要功能，可在结果页增加与该功能相关的描述性内容；除此之外，结果页也可以承载一些附加价值操作，例如提供抽奖、关注公众号等功能入口。
<div class="weui_msg">
<div class="weui_icon_area"><i class="weui_icon_success weui_icon_msg"></i></div>
<div class="weui_text_area">
<h2 class="weui_msg_title">操作成功</h2>
<p class="weui_msg_desc">内容详情，可根据实际需要安排</p>
</div>
<div class="weui_opr_area">
<p class="weui_btn_area">
<a href="#" class="weui_btn weui_btn_primary">确定</a>
<a href="#" class="weui_btn weui_btn_default">取消</a>
</p>
</div>
<div class="weui_extra_area">
<a href="">查看详情</a>
</div>
</div>
Article
文字视图显示大段文字，这些文字通常是页面上的主体内容。Article 支持分段、多层标题、引用、内嵌图片、有/无序列表等富文本样式，并可响应用户的选择操作。
在微信客户端 webview 中使用 Article，必须保证文字有足够的可读性和可辨识性、使用规范字体、保证足够的段间距、段首无缩进。
<article class="weui_article">
