Was wondering if their is an etiquette on the order of things following a declaration?

Question

for example: p {
font-size: .....
font-family:.......
font-weight:.......
color:...........
height:........
width:..........
background-image:....
}
and so on.. would it matter the order of these and other css properties? Or is it just how the person feels like doing it?

Answer 1

order will matter if you use the same attribute

the last one will override the one before it

div{
color:red;
color:green;
}

green will be the one that applied
