		Simple margin container.
	</brief_description>
	<description>
		Adds a top, left, bottom, and right margin to all [Control] nodes that are direct children of the container. To control the [MarginContainer]'s margin, use the [code]margin_*[/code] theme properties listed below.
		[b]Note:[/b] Be careful, [Control] margin values are different from the constant margin values. If you want to change the custom margin values of the [MarginContainer] by code, you should use the following examples:
		[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);
