I have a website which is using a child theme of Twenty Twelve.
As part of the design process, I had to edit /twentytwelve/css/ie.css
.
Is it possible to save this file in my child theme, and keep twentytwelve's version as it was by default? This would ensure if Twenty Twelve is ever updated, I won't lose the changes I made to /twentytwelve/css/ie.css
.
