The p utility give padding to an element.
You can choose which kind of padding you will add, for example if you set `px="3"` your element will receive an horizontal padding of 3.
You can use the following p attributes :
I'm a div with p="2"
I'm a div with px="2"
I'm a div with py="2"
I'm a div with pb="2"
I'm a div with pt="2"
I'm a div with pl="2"
