Can anyone help me figure out why this code is not changing the title text color?

I am trying to implement this custom CSS to move the summary content titles over the images with a dimming effect. It all works except the text color does not change to white, but rather stays as the site wide color that I use for when it is below the image. This is the code block I am using. 

 

#block-yui_3_17_2_1_1554844439456_8066 {

  @media screen and (min-width:800px){

  .summary-item {

    position: relative;

 

    img {

      transition: all .5s ease!important;

    }

 

    .summary-content {

      position: absolute;

      color: #fff!important;

      top: 50%;

      left: 50%;

      opacity: 0;

      pointer-events: none;

      transition: all .5s ease;

      transform: translate(-50%, -50%);

      -webkit-transform: translate(-50%, -50%);

      -ms-transform: translate(-50%, -50%);

      -moz-transform: translate(-50%, -50%);

    }

    .summary-title, .summary-metadata--primary, .summary-metadata--secondary, .summary-excerpt   {

      color: #fff!important;

    }

  }

  .summary-item:hover {

    img {

      -webkit-filter: brightness(50%);

      filter: brightness(50%);

    }

 

    .summary-content {

      opacity: 1;

    }

  }

}

}
