h5开发中安卓和ios的问题

请问我在h5开发中发现，代码在安卓里能够很好运行，但是一旦到ios的safari里就会出现排版混乱（几排文字全部挤到顶部去了），检查代码很久没有发现问题，所以求助大家

#page1 > .p1_title p{right: 10%;left: 10%;}
.p1_title_1{bottom: 48%;}
.p1_title_2{bottom: 44%;}
.p1_title_3{bottom: 40%;}
.p1_title_4{bottom: 36%;}
.p1_title_5{bottom: 32%;}
.p1_title_6{bottom: 28%;}

把html贴出来，还有就是去看看，top,right,bottom,left这些元素什么情况下生效，你是不是得给设置这些属性的元素定位啊
