A brief discussion on VUE uni-app conditional coding and page layout

Conditional compilation

Conditional compilation uses special comments as markers. During compilation, the code in the comments is compiled to different platforms based on these special comments.

Writing method: Start with #ifdef or #ifndef plus %PLATFORM% and end with #endif.

#ifdef : if defined only exists on certain platforms

#ifndef ：if not defined exists on all platforms except certain ones

%PLATFORM% : Platform name

Page Layout

scss specification, rpx width in iPhone6/7/8 is 750, 2rpx = 1px

<style lang="scss">
	@import "./news.css"; // Load other css files .f1{
		font-size: 50rpx;
		.c3{
			background-color: red;
		}
	}
</style>
