        </div>
        <div class="slide__slide-buttons">
          <a href="#">Explore</a>
          <a href="#">Learn more</a>
        </div>
      </div>
      <!--slide-end-->
    </div>
  </div>
</section>

There is such a class

.slider__slide

but in further layout, you can reach this class a few more times when you add more sliders. Where am I making a mistake in class naming?

Answer 1

First, check the layout against the html tree until you make mistakes.
Secondly, if your slides are slightly different, then you can add a modifier, for example, to set different classes differently. <div class="slider__slide slider__slide--big">
