Responsive UIGridLayout

[JKurczak]

1. What do you want to achieve?
   Change CellSize on resize view port.

2. What solutions have you tried so far?
   Did you look for solutions on the Developer Hub?
   I wrote a small script that detects changes in ViewportSize when inventory is open. Will this solution affect the performance?

local player = game.Players.LocalPlayer
local InventoryGui = player.PlayerGui.InventoryGui

script.Parent.MouseButton1Click:Connect(function()
	if not InventoryGui.Enabled then
		InventoryGui.Enabled = true

		workspace.CurrentCamera:GetPropertyChangedSignal("ViewportSize"):Connect(function()
			local width = workspace.CurrentCamera.ViewportSize.X

			if(width < 900) then
				for i, v in pairs(InventoryGui:GetDescendants()) do
					if v:IsA("UIGridLayout") then
						v.CellSize = UDim2.new(0.24, 0, 0.085, 0)
					end
				end
			else
				for i, v in pairs(InventoryGui:GetDescendants()) do
					if v:IsA("UIGridLayout") then
						v.CellSize = UDim2.new(0.18, 0, 0.08, 0)
					end
				end
			end
		end)
		
	else
		InventoryGui.Enabled = false
	end
end)

Thanks
