	<brief_description>
		A container that keeps a margin around its child controls.
	</brief_description>
	<description>
		[MarginContainer] adds an adjustable margin on each side of its child controls. The margins are added around all children, not around each individual one. To control the [MarginContainer]'s margins, use the [code]margin_*[/code] theme properties listed below.
		[b]Note:[/b] The margin sizes are theme overrides, not normal properties. This is an example of how to change them in code:
		[codeblocks]
		[gdscript]
		# This code sample assumes the current script is extending MarginContainer.
		var margin_value = 100
		add_theme_constant_override("margin_top", margin_value)
		add_theme_constant_override("margin_left", margin_value)
		add_theme_constant_override("margin_bottom", margin_value)
		add_theme_constant_override("margin_right", margin_value)
		[/gdscript]
		[csharp]
		// This code sample assumes the current script is extending MarginContainer.
		int marginValue = 100;
		AddThemeConstantOverride("margin_top", marginValue);
		AddThemeConstantOverride("margin_left", marginValue);
		AddThemeConstantOverride("margin_bottom", marginValue);
		AddThemeConstantOverride("margin_right", marginValue);
		[/csharp]
