Blinking text in card

Hi everyone! I made a card with text which depends on the state of the entity, here is a code of styles (custom:button-card):

name:
  - justify-self: start
  - font-size: 14px
  - padding-left: 0px
  - font-weight: 550
  - opacity: '0.7'
  - color: |
      [[[
        var state = entity.state;
        if (state == '0') return 'cyan';
        if (state == '64' | state == 'unavailable') return 'yellow';
        if (state == '1' | state == '2' | state == '3') return 'red';
      ]]]

But I want to make the red text to blink, how I am supposed to do this?
