CSS changes not reflicting inside the Modal

[GhitaB]

i'm trying to style one message inside a modal pop up in the service scriptbut seems like the changes are not reflicting

CUSTOM_MESSAGE:"<p class='custom-msg' please use this <a href='google.com'>Link</a></p>",

and in the controller this is what i have:

	var modalParam = {
			message: $sce.trustAsHtml($scope.data.i18n.CUSTOM_MESSAGE_ISOLV),
			
		};

.custom-msg {
color: red !important;
}

how can i let the changes to be visible on the modal.
