阅读更多关于 How to handle responsive images with vertical rhythm?

问题 I'm developing an HTML page using Compass/SCSS and a vertical rhythm approach. I've set up a baseline and specified heights for paragraphs and headings in rem units. It works great and lays on a vertical rhythm grid nicely. However, I have a central image that takes 100% width of the column (I want it to be responsive and scale with the browser window).

阅读更多关于 Sass 3.4 Removing forward slash on a string
