我将 Susy span-column()mixin 设置为的元素，不服从它。它们错位得非常轻微。如何实现 HTML 元素的完美对齐？
整个网站错位的屏幕截图
细节：<header>和<nav>错位
细节：<section class="main">错位
这是我的 Sass 代码
@import compass
@import susy
@import normalize

Vertical grids are a compas feature. See the compass docs for baseline grid background. You won't be able to show both grids at once on the same element without a bit more work. Maybe we should integrate that somehow in Susy 2.0? Vertical grids are a compas feature. See the compass docs for baseline grid background.
