第二个主题页面的布局,涉及了背景图,商店,门,灯等几个元素。为了方便静态页面布局,可以用个小技巧,修改下代码通过scrollTo直接定位到当前页面
//用来临时调整页面,1个页面宽,也就是第二个页面 swipe.scrollTo(container.width(),0)
新建一个pageB.css的样式文件,我们把与第二个页面相关的css样式都写入这个文件中,这个布局挺简单,自适应的关系采用的是百分比布局,可以按照UI设计的尺寸计算百分比
稍微注意下的就是商店的灯的亮度切换采用的是切换背景图片,背景图如果是没有预加载的话就有一个闪屏的问题,所以特意做了一个b_background_preload的节点让图片先加载,设置一个坐标不可见
商店的门是可以开关的所以在布局上会有个一左一右的处理
最后我们会用一个background-size:100% 100%的属性处理图片,不管分辨率怎么变化,图片始终都是填充整个尺寸
看看右边就是布局后的效果
