# You may have used before

- transfrom: translateX()
- transfrom: translateY()
- transform: rotate(45deg)
- transform: skew()
- transform: scale()
- etc.

# You may have seen or used (or copy pasted)

{ transfrom: matrix(a, b, c, d, e, f); }

# What the actual.... f***

Why should I even bother...

# What is a transformation?

Think of it as a map() method which applies a given matrix to each vector

# So... what is the matrix?

The matrix represents the future position of our vectors that define our space

Let that sink in for a moment

# Questions?

{ transform: matrix(a, b, c, d, dx, dy) }

# Knowing this we can control the matrix

# Questions?

# na... just kidding
