Problem with font size style for alert dialog and ion-options dialog?


Hi, I have a problem that I can not change font size for dialog wih radio box, or check box and ion-option dialog.
which is I set override value in


like this

$alert-button-font-size: 18px;
$alert-md-title-font-size: 30px;
// $alert-md-sub-title-font-size:50px;
$alert-md-message-font-size :23px;
// $alert-md-radio-label-padding-top:55px;

and it did change only title and button but message in the radio box did not. I find many way but not luck.
so if anyone knew please help , thank you
