        <p>This is by far the biggest deep dive I've seen on CSS Variables posted to the web and it's merely Chapter One of complete e-book on the topic.</p>
        <p>Truth is, I'm still on the thick of reading through this myself, but had to stop somewhere in the middle to write this up and share it because </p>
        <p>it's just that gosh-darned useful. For example, the post goes into great detail on three specific use cases for CSS Variables and breaks the code </p>
        <p>
        down to give a better understanding of what it does, in true tutorial fashion.
        Scoping, inheritance, resolving multiple declarations, little gotchas_there's plenty in here for beginners and advanced developers alike.</p>
        </ReactReadMore>
      </div>
    );
  }

      height: 20px;
      background: linear-gradient(rgba(255, 255, 255, 0.01), #fff); /* transparent keyword is broken in Safari */
      pointer-events: none;
    }
  }

  &[data-expanded=true],
  &[data-actions-visible=false] {
    .react-read-more-wrapper {
