CSS：

      /* Sticky footer styles
  -------------------------------------------------- */

  html,
  body {
    height: 100%;
    /* The html and body elements cannot have any padding or margin. */
  }

  /* Wrapper for page content to push down footer */
  #wrap {
    min-height: 100%;
    height: auto !important;
    height: 100%;
    /* Negative indent footer by it's height */
    margin: 0 auto -100px;
  }

  /* Set the fixed height of the footer here */
  #push,
  #footer {
    height: 100px;
  }
  #footer {
    background-color: black;
  }

  /* Lastly, apply responsive CSS fixes as necessary */
  @media (max-width: 767px) {
    #footer {
      margin-left: -20px;
      margin-right: -20px;
      padding-left: 20px;
      padding-right: 20px;
    }
  }

Answer 1

也許您終於找到了ID，但這是我使用的

#footer {
position: absolute;
bottom: 0;
width: 100%;
height: 60px;
}

Answer 2

將此添加到CSS ：

#footer {
  position: fixed;
}

Answer 3

/* Negative indent footer by it's height */
    margin: 0 auto -100px;

您能解釋一下您要達到的目標嗎？
