I added three images by bootstrap. but these images display in left side of page, while I want them display in center of page.

How can I do it?

<div id="carouselExampleInterval" class="carousel slide" data-ride="carousel" root="teal">
  <div class="carousel-inner">
    <div class="carousel-item active" data-interval="10000">
      <img src="img/pic1.jpg" class="d-block w-100" alt="..."width="1010"height="600px">
    </div>
    <div class="carousel-item" data-interval="2000">
