如何使 Bootstrap 轮播标题拉伸轮播的整个宽度?

How can I make a Bootstrap carousel caption stretch the full width of the carousel?

我有一个轮播,它是整个页面的宽度。现在我需要使 carousel-caption 成为页面的全宽以及黄色背景。背景应为页面的全宽,但实际标题文本应居中。

它应该是这样的:

这是现在的样子:

HTML:

<!--START CAROUSEL-->
<div id="carousel-example-generic" class="carousel slide" data-ride="carousel" data-interval="false">
  <!-- Wrapper for slides -->
  <div class="carousel-inner" role="listbox">
    <div class="item active">
      <img src="../../images/LD/desktop_hero1.png" alt="...">
      <div class="carousel-caption">
        Text for caption 1 here.
      </div>
    </div>
    <div class="item">
      <img src="../../images/LD/desktop_hero2.png" alt="...">
      <div class="carousel-caption">
        Text for caption 2 here.
      </div>
    </div>
    <div class="item">
      <img src="../../images/LD/desktop_hero3.png" alt="...">
      <div class="carousel-caption">
        Text for caption 3 here.
      </div>
    </div>
  </div>

  <!-- Controls -->
  <a class="left carousel-control" href="#carousel-example-generic" role="button" data-slide="prev">
    <span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>
    <span class="sr-only">Previous</span>
  </a>
  <a class="right carousel-control" href="#carousel-example-generic" role="button" data-slide="next">
    <span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span>
    <span class="sr-only">Next</span>
  </a>
</div>       
<!--END CAROUSEL-->

CSS:

<style type="text/css">
    .carousel-caption {
     max-width: 100%;
     width:100%;
     background-color: #ffb81c;
    }
</style>

你只需要添加 text-align: center 因为它实际上已经使用了整个宽度

如果有东西漂浮,你可以使用 clearfix 来解决它,检查这个 jsfidlle

title example

<div class="carousel-caption">
    <h1>
    Text for caption 1 here.
    </h1>
  </div>


.carousel-caption h1 {
 max-width: 100%;
 background-color: #ffb81c;
 text-align:center;
}

PD。我添加了 h1 标签以获得更好的语义结构。

carousel-caption class 声明 div 具有绝对定位,其位置距左侧 15%。

因此您可以尝试覆盖它。这是 css:

.carousel-caption {
    max-width: 100%;
    width:100%;
    background-color: #ffb81c;
    left: 0;
}
