Question

css

There is a heading on the left and two paragraphs on the right, leading to the section code:

<section id="our_history">
    <div class="container">
      <div class="row">
        <div class="col">
          <h2 class="history d-flex justify-content-center">
            our<br>interesting<br> history
          </h2>
        </div>
        <div class="col">
          <p class="p_history d-flex justify-content-end">
            Science in the media always seems to be very one-sided.

          </p>
        </div>
      </div>
    </div>
  </section>

here is the css code for the section:

#our_history {
  border-bottom: 1px solid #f1f1f1;
  padding: 100px 0;
}

.history {
  align-items: center;
  font-size: 48px;
  line-height: 60px;
  font-weight: 700;
  text-transform: uppercase;
  color: #464646;
  margin: 0;

}
.p_history {
  margin-bottom: 50px;
}

The bottom line is that align-items: center does not work, I went into developer mode and saw this... (on the screen)

Help)) I'm tired of this specifically))
