[b]Note:[/b] If using a font with [member FontFile.multichannel_signed_distance_field] enabled, its [member FontFile.msdf_pixel_range] must be set to at least [i]twice[/i] the value of [theme_item outline_size] for outline rendering to look correct.

</theme_item>

[StyleBox] used when the [OptionButton] is focused. The [code]focus[/code] [StyleBox] is displayed [i]over[/i] the base [StyleBox], so a partially transparent [StyleBox] should be used to ensure the base [StyleBox] remains visible. A [StyleBox] that represents an outline or an underline works well for this purpose. To disable the focus visual effect, assign a [StyleBoxEmpty] resource. Note that disabling the focus visual effect will harm keyboard/controller navigation usability, so this is not recommended for accessibility reasons.
