I am unable to find the link to the built-in css of the theme. I am currently using the Oulipo theme but would like to edit/add some css. However, I don't see any link to go and edit it. Is it possible in the first place to edit and if yes where do I go and do some changes to fit my requirement? Basically I want to hide the tags listing from the posts in my blog but would like to keep them hidden and not remove at all.
The blog I need help with is mandeepdeka.wordpress.com.
