Without additional context, here is a general explanation:
The theme.transitions.create
function is a helpful tool provided by Material-UI for creating custom CSS transitions. It takes two arguments: "props" and "options".
The props argument can be a string or an array of strings that indicate which CSS properties should be transitioned. In the given example, color and transform properties are being transitioned.
The options argument is an optional object with various properties to customize the transition further. The duration property specifies how long the transition will last, set in this case to
theme.transitions.duration.shortest
. This means it will use the shortest duration specified in your theme.
Additional properties in the options object include easing, which defines the easing function for the transition, and delay, which determines the time before the transition begins.
