How to remove whitespaces in Bootstrap Carousel?

Question

I have a problem with Bootstrap Carousel - I want it to be 100% width, from edge to edge, but I can't get rid of small whitespaces on the left and right (margins?). I'he already tried everything: borders, margins, paddings, outlines in a different park of code (images, divs, bootstrap.css) - nothing helps. Any clues? Here's what I'm talking about.

Here is part of my code:

<div class="container" style="width: 100%;">
  <div id="myCarousel" class="carousel slide" data-ride="carousel" data-interval="3000" style="">
    <!-- Indicators -->
    <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>

    <!-- Wrapper for slides -->
    <div class="carousel-inner" role="listbox" style="margin: 0px; padding: 0px; border: 0px; margin: none; ">
      <div class="item active">
        <img src="img/back_1.JPG" alt="Chania" style="min-width:100%; margin: none; padding: none;">
      </div>

      <div class="item">
        <img src="img/back_2.jpg" alt="Chania" style="width:100%;">
      </div>

      <div class="item">
        <img src="img/back_3.jpg" alt="Flower" style="width:100%;" >
      </div>

      <div class="item">
        <img src="img/back_4.jpg" alt="Flower" style="width:100%;">
      </div>
    </div>
  </div>
</div>

The white space on either side of your carousel is coming from the container class, which adds padding-left: 15px and padding-right: 15px. While you could overwrite this, it would make more sense to simply remove the class from your main .container <div> element.

Also, note that <div> elements are 100% with by default, so you don't actually need this outer <div> container at all; you can simply start your carousel with <div id="myCarousel">, as is shown in the following example:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />

<div id="myCarousel" class="carousel slide" data-ride="carousel" data-interval="3000" style="">
  <!-- Indicators -->
  <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>
  <!-- Wrapper for slides -->
  <div class="carousel-inner" role="listbox" style="margin: 0px; padding: 0px; border: 0px; margin: none; ">
    <div class="item active">
      <img src="http://placehold.it/100" alt="Chania" style="min-width:100%; margin: none; padding: none;">
    </div>
    <div class="item">
      <img src="http://placehold.it/100" alt="Chania" style="width:100%;">
    </div>
    <div class="item">
      <img src="http://placehold.it/100" alt="Flower" style="width:100%;">
    </div>
    <div class="item">
      <img src="http://placehold.it/100" alt="Flower" style="width:100%;">
    </div>
  </div>
</div>

Hope this helps! :)
