How do I set custom CSS for my IPython/IHaskell/Jupyter Notebook?

To add custom CSS to a particular notebook you can use HTML. Add and execute a regular Python code cell with the following content: from IPython.core.display import HTML HTML(“”” <style> // add your CSS styling here </style> “””) Alternatively (thanks @abalter) use the %%html cell magic: %%html <style> // add your CSS styling here </style>
