WeUI 是一套同微信原生视觉体验一致的基础样式库，由微信官方设计团队为微信内网页和微信小程序量身设计，令用户的使用感知更加统一。
WeUI是微信Web服务开发的UI套件, 目前包含12个模块 (Button, Cell, Toast, Dialog, Progress, Msg, Article, ActionSheet, Icons, Panel, Tab, SearchBar)。
按钮（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。

单元格（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 headerweui_cells_title以及cellsweui_cells。
cell由thumbnailweui_cell_hd、bodyweui_cell_bd、accessoryweui_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classweui_cell_primary即可。
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：
<link rel="stylesheet" href="//res.wx.qq.com/open/libs/weui/0.4.3/weui.min.css"> <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> <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="javascript:;"> <div class="weui_cell_hd"> <img src="" alt="icon" style="width: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="javascript:;"> <div class="weui_cell_hd"> <img src="" alt="icon" style="width: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>
对话框（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。
<link rel="stylesheet" href="//res.wx.qq.com/open/libs/weui/0.4.3/weui.min.css"> <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<br>...</div> <div class="weui_dialog_ft"> <a href="javascript:;" class="weui_btn_dialog default">取消</a> <a href="javascript:;" 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="javascript:;" class="weui_btn_dialog primary">确定</a> </div> </div></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。
<link rel="stylesheet" href="//res.wx.qq.com/open/libs/weui/0.4.3/weui.min.css"> <div id="toast"> <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>
<link rel="stylesheet" href="//res.wx.qq.com/open/libs/weui/0.4.3/weui.min.css"> <div id="loadingToast" class="weui_loading_toast"> <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>
结果页(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。
<link rel="stylesheet" href="//res.wx.qq.com/open/libs/weui/0.4.3/weui.min.css"> <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="javascript:;" class="weui_btn weui_btn_primary">确定</a> <a href="javascript:;" 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>
文章内容详情页
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。
<link rel="stylesheet" href="//res.wx.qq.com/open/libs/weui/0.4.3/weui.min.css"> <article class="weui_article"> <h1>大标题</h1> <section> <h2 class="title">章标题</h2> <section> <h3>1.1 节标题</h3> <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
