Looks pretty good. For the bubble you can see what I did:

        <div class="pop-up">
          <p>
            <span>185</span>
            GB Left
          </p>
          <div class="triangle">
          </div>
        </div>

.pop-up{
  display: flex;
  flex-direction: column;
  justify-content: center;
  align-items: center;

  position: absolute;
  z-index: 10000;

  right: 0px;
  top: -70px;

  width: 150px;
  height: 65px;

  border-style: none;
  border-radius: 10px 10px 0px 10px;

  background-color: white;
}

.triangle{
  width: 0;
  height: 0;
  border-left: 20px solid transparent;
  border-right: 0px solid transparent;
  border-top: 25px solid white;
  position: absolute;
  top: 100%;
  right

I had difficulty with this as well when I did the challenge, but once I got it it seemed pretty simple.
