css 如何调整页脚容器的大小？

我使用Bootstrap来制作我正在工作的代码（作为新手练习的明智之举）
我得到了一些问题的容器大小的页脚和我已经坚持了几个小时没有找到解决方案在这个..
enter image description here作为照片（在链接中），页脚大小我最初认为是占用屏幕的全部宽度，并且比这要宽得多。
我认为页脚宽度已经缩小（尽管Bootstrap片段中的原始页脚大小看起来合适）只是因为上面的Carousel部分是自定义的大小。所以上面的部分（Carousel）可能会影响页脚的容器大小，然后自动影响其上面（自定义）容器的大小，这是我根本不想要的。
有什么想法如何使页脚不受上部容器尺寸的影响？我真的很感激任何帮助…

原代码：*

<style>
    .brand-logo {

      height: 50px;
      padding: 0;
      margin-bottom: 6px;
    }

    .feature-icon img {
      width: 4rem;
      height: 4rem;
      border-radius: .75rem;
    }

    .divider {
    border-top: 1px solid #ccc;
    margin-top: 30px;
    margin-bottom: 30px;
    }

#carouselExampleCaptions {
  max-width: 800px; /* Set the maximum width of the carousel */
  margin: 0 auto; /* Center the carousel horizontally */
}

.carousel-inner {
  max-height: 700px; /* Set the maximum height of the carousel */
}

img {
  object-fit: cover;
}

  </style>

我试着添加了很多语法，比如max-width，container-fluid等等。可悲的是，没有工作了。

你的页脚似乎在Bootstrap .container类中，它被设计成一个固定宽度的容器。这就是为什么它没有占据整个屏幕的宽度。
一个快速解决方法是将页脚的.container类更改为.container-fluid。这个类提供了一个全宽容器，跨越视口的整个宽度。你可以这样做：

<!-- Footer Section -->
<div class="container-fluid"> <!-- Change here -->
  <footer class="py-5">
   ....

<style>
  /* CSS code */
  footer {
     height: 100px; /* Adjust the height as  your requirements */
     width: 100%; /* Adjust the width as per your requirements */
     background-color: #f1f1f1;
    }
   </style>

<footer>
<!-- Footer content -->

`在上面的代码中，我为footer元素定义了一个CSS规则。通过将height属性设置为100px，可以调整页脚的高度。类似地，width属性被设置为100%，使页脚跨越其容器的整个宽度。

既然你想成为一名程序员，就必须学习两件重要的事情：调试和缩进。
首先，你的代码是非常混乱的，这就是为什么打字错误和小错误可能会发生，这就是缩进的问题。第二，调试，如果你的代码有什么问题，打开Developer Tools并调试问题。
如果你这样做，你会看到以下内容：

名为carouselExampleCaptions的容器接受了其中的所有元素（carousel、divider和footer），而您已经将max-width: 800px;设置为该容器，这就是问题所在。其中的任何元素最大会收缩到800px。
解决方案是将分隔符和页脚从carouselExampleCaptions移动，如下所示：

.brand-logo {
    height: 50px;
    padding: 0;
    margin-bottom: 6px;
}

.feature-icon img {
    width: 4rem;
    height: 4rem;
    border-radius: 0.75rem;
}

.divider {
    border-top: 1px solid #ccc;
    margin-top: 30px;
    margin-bottom: 30px;
}

#carouselExampleCaptions {
    max-width: 800px; /* Set the maximum width of the carousel */
    margin: 0 auto; /* Center the carousel horizontally */
}

.carousel-inner {
    max-height: 700px; /* Set the maximum height of the carousel */
}

img {
    object-fit: cover;
}
