Adding drop shadow to outline button text

I’m able to add a drop shadow to the button box itself, but I’m trying to add a drop shadow to the button text (i.e. LEARN MORE)  since it is a transparent outline style button. The buttons are white against full page images and I’d like them to be more legible.

Thanks!

Try this in your custom CSS.

.sqs-block-button-element {
  text-shadow:2px 2px gray;
}

Can you share link to page in screenshot?
