How to install a CERN overwrite theme and where can I get it from?
I am developing a website on Drupal, and I need to change the footer (to merge two footer blocks into one). That's what I heard from CERN tech support: "If you want to modify the default CERN theme, you must install the CERN overwrite theme locally and then modify the css within that theme."
What is meant by "locally", on the website that I am working on, or I should create a copy on my machine (localhost) and then upload the changes to the website?
Thank you in advance!
