How to fade a black frame?

I'm trying to fade a black frame where it starts when you load up the game but then fades out, i tried to do this myself and searched on youtube and etc, but couldn't find anything, so can you guys like explain it or even probably give me a code for it? But i'm mainly would like how to do it.

You would use a for loop for this. The for loop is a way of running a set of code for a defined number of times.

This is the syntax for for loop

for variable = StartingNum, FinishingNum, Increment do
end 

##To need to know materials for this piece

For Loop

BackgroundTransparency

This is an example

-- Declaration Section 
local BlackFrame = script.Parent --Where your frame is 

-- Processing Section 

for number = 1, 0, -0.1 do --Declaring a loop
	BlackFrame.BackgroundTransparency = number --Changing BlackFrame's Transparency and decreasing it by 0.1 each millisecond. 
	wait()
end 

wait(5) --Waiting for 5 seconds before reverting back to original transparency

for number = 0, 1, 0.1 do
	BlackFrame.BackgroundTransparency = number
	wait()
end 

And that is how you do it. Comment below if you still don't understand it

Have a lovely day of coding
