carousel resizing

I have a working carousel but I am looking to resize the whole thing. I am able to resize the images but the next and previous buttons and the image indicator don't change and i can't figure out how to change these to match what ever the size of the images are.

<div id="homeCarousel" class="carousel slide" data-ride="carousel">
  <ol class="carousel-indicators">
    <li data-target="#homeCarousel" data-slide-to="0" class="active"></li>
    <li data-target="#homeCarousel" data-slide-to="1"></li>
    <li data-target="#homeCarousel" data-slide-to="2"></li>
  </ol>
  <div class="carousel-inner">
    <div class="carousel-item active">
      <img class="d-block w-100" src="images/Makita.png" alt="First slide">
    </div>
    <div class="carousel-item">
      <img class="d-block w-100" src="images/Metabo.png" alt="Second slide">
    </div>
    <div class="carousel-item">
      <img class="d-block w-100" src="images/Bosch.png" alt="Third slide">
    </div>
  </div>
  <a class="carousel-control-prev" href="#homeCarousel" role="button" data-slide="prev">
    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
    <span class="sr-only">Previous</span>
  </a>
  <a class="carousel-control-next" href="#homeCarousel" role="button" data-slide="next">
    <span class="carousel-control-next-icon" aria-hidden="true"></span>
    <span class="sr-only">Next</span>
  </a>
</div>
