本文介绍了移动端Web开发中遇到的挑战，包括空间转换导航栏的实现，小兔仙确认订单页面的文字定位问题，以及游乐园页面的设计与布局。在导航栏部分，提到了li元素高100%导致的a元素定位问题，以及空间转换的技巧。在小兔仙页面，讨论了文字定位的难题。在游乐园页面，重点是标准像素选择、CSS样式应用及底部功能栏的修正。
1.空间转换导航栏-pc
遇到的问题：
li设置高100%导致a定位li把所有a定到一起。
空间观察角度推荐：x-20deg，y30deg。
图片空间旋转以后，这个图片坐标轴也会随之旋转。

2.小兔仙确认订单-sj
遇到的问题，文字不能较好使用行高定位，而是用边距定位，导致位置不够精确。有大佬的话求一下解决办法。

3.游乐园-sj
html设计稿选择到标准像素375
head 引入网页标题图标 favicon.ico
引入css样式表
引入iconfont
body最后引入js
遇到的问题：
1.底部功能栏忘记fixed导致最后一个item和fotter有很大间距
2.a字体图标使用width改的大小，导致280像素下字体乱排，改用fontsize修复。
