Styling bootstrap carousel indicators

I'm trying to get the default bootstrap carousel indicators to be very thin yellow lines stuck at the bottom as shown below.

I got them to be at the bottom of the page but I can't seem to change them into rectangles or change their color.

HTML

<ol class="carousel-indicators">
    <li data-target="#myCarousel" data-slide-to="0" class="active"></li>
    <li data-target="#myCarousel" data-slide-to="1"></li>
    <li data-target="#myCarousel" data-slide-to="2"></li>
    <li data-target="#myCarousel" data-slide-to="3"></li>
</ol>

CSS

.carousel-indicators {
    margin: 0px;
    height: 0px;
}

.carousel-indicators ol {
    width: 100%;
}

.carousel-indicators li {
    height: 3px !important;
    border-radius: 0px !important;
    width: 25%;
}

This snippet changes prev and next Carousel icon controls for library react-bootstrap :

& span.carousel-control-prev-icon, & span.carousel-control-next-icon{
        background-color: black;
    }

Yeah, only the background. The icon itself is an xml image so couldn't find a way to change the colors. :/

Great css! I played with it to come up with ball indicators in half-white and the active indicator in yellow.

ol.carousel-indicators {
     position: absolute;
     bottom: 5px;
     margin: 0;
     left: 0;
     right: 0;
     width: auto;
}

ol.carousel-indicators li, ol.carousel-indicators li.active {
     width: 1rem;
     height: 1rem;
     margin: 0;
     border-radius: 50%;
     border: 0;
     background: transparent;
}

ol.carousel-indicators li {
     background: rgba(255,255,255,0.39);
     margin-left: .5rem;
     margin-right: .5rem;
}

ol.carousel-indicators li.active {
     background: yellow;
}

i have just wrote similar code for myself, i think it will help you a little bit more. by using Flex layout you can similarly stretch indicators without worrying about their width flex-grow:1; makes this job

https://codepen.io/ophiuch/pen/Jzowbo

.carousel  /*slider */
{
	position: relative;
}
.carousel .carousel-indicators	/* indicator wrapper*/
{
	position: absolute;
	bottom: 0;
	left:0px;
	width: 100%;
  	margin: 0;
  	left: 0;
 	right: 0;
 	width: 100%;
 	display: flex;	/* this is for indicators  */
}
#headcarousel_container .carousel-indicators li /* indicators*/
{
	flex-grow: 1;  /* make all indicator li similarly stretched */
	height: 40px;
	border-radius: 2px;	
}

#headcarousel_container .carousel-indicators li.active
{
	background-color:rgba(251,222,87,0.5) ;/* changes indicators color when it is active*/ 
}
.carousel .carousel-inner .item img
{
	width: 100%;
	height: 100vh;
	object-fit: cover; 
}

Something like this? Note that the width is not totally accurate because I just made it 33%.

.item img {
  width: 100%;
  height: auto
}

.carousel {
  position: relative;
  width: 200px;
  height: 100px;
}

ol.carousel-indicators {
  position: absolute;
  bottom: 0;
  margin: 0;
  left: 0;
  right: 0;
  width: auto;
}

ol.carousel-indicators li,
ol.carousel-indicators li.active {
  float: left;
  width: 33%;
  height: 10px;
  margin: 0;
  border-radius: 0;
  border: 0;
  background: transparent;
}

ol.carousel-indicators li.active {
  background: yellow;
}
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />

<div id="carousel" class="carousel slide" data-ride="carousel">
  <ol class="carousel-indicators">
    <li data-target="#carousel" data-slide-to="0" class="active"></li>
    <li data-target="#carousel" data-slide-to="1"></li>
    <li data-target="#carousel" data-slide-to="2"></li>
  </ol>
  <div class="carousel-inner" role="listbox">
    <div class="item active">
      <img src="http://placehold.it/200x100" alt="Slide 1">
      <div class="carousel-caption">
        Slide 1
      </div>
    </div>
    <div class="item">
      <img src="http://placehold.it/200x100" alt="Slide 2">
      <div class="carousel-caption">
        Slide 2
      </div>
    </div>
    <div class="item">
      <img src="http://placehold.it/200x100" alt="Slide 3">
      <div class="carousel-caption">
        Slide 3
      </div>
    </div>
  </div>
  <a class="left carousel-control" href="#carousel" role="button" data-slide="prev">
    <span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>
