小程序页面在ios出现横向滚动条问题

原因：元素设置了width：100%然后又设置了margin或者padding可以撑大盒子的边距。此时在ios就会出现横向滚动条解决给盒子加box-sizing: border-box全局加

page, view, scroll-view, swiper, movable-area, cover-view, text, icon, rich-text,progress, button, checkbox-group, checkbox, form, input, label, picker,picker-view, radio-group, slider, switch, textarea, navigator, audio, image,video, live-player, live-pusher, open-data, web-view {box-sizing: border-box;}
