🔰 How to Use Jupyter Notebook

The Jupyter Notebook is an incredibly powerful tool for interactively developing and presenting data science projects.

This article will walk you through how to use Jupyter Notebooks for data science projects and how to set it up on your local machine.

1. CSS isn’t broken — your div just gave up on life.
Try: min-height: 100vh; 🚑

== is for loose relationships.
Use === if you want commitment. 💍

Want faster sites?
Replace PNGs with webp. Smaller, sharper, sexier. 📸


2. Centering in CSS used to be sorcery. 🧙‍♂️
Now it’s just:

display: grid;
place-items: center;

3. Bored of boring bullets?
Spice up your list with:

list-style-type: '🔥';

4.

z-index

not working?
Make sure the element isn’t a ghost.

position: relative;
