jQuery WeUI 是專(zhuān)為微信公眾賬號(hào)開(kāi)發(fā)而設(shè)計(jì)的一個(gè)簡(jiǎn)潔而強(qiáng)大的UI庫(kù)，包含全部WeUI官方的CSS組件，并且額外提供了大量的拓展組件，豐富的組件庫(kù)可以極大減少前端開(kāi)發(fā)時(shí)間。
jQuery WeUI 的最大特點(diǎn)是它只提供UI組件，并不會(huì)對(duì)項(xiàng)目所使用的框架和其他庫(kù)有任何的限制，幾乎可以在任何環(huán)境下使用。無(wú)論你的項(xiàng)目是基于jQuery，還是 React, Angular, Vue， 你都會(huì)發(fā)現(xiàn) jQuery WeUI 能非常方便的和他們結(jié)合使用。既是你的項(xiàng)目是一個(gè)有很悠久歷史的老項(xiàng)目，也幾乎可以做到拿來(lái)即用。
weui框架暫時(shí)只有css文件，并沒(méi)有js文件實(shí)現(xiàn)其功能，我在其html+css后面增加了js實(shí)現(xiàn)其功能，為大家提供方便，也為自己保存記錄。
