Question

我用bootstrap开发我的网站。我有一个导航栏，图像滑块，产品部分和一个关于+页脚部分。出于某种原因，我的产品部分正在推动关于页面的部分，我似乎无法找出原因？另外：当我缩小屏幕时，这些部分是正确的距离，这个问题似乎只在全屏时出现。

html：

      <!-- Products section -->
  <section id="products">
    <div class="col-sm-3 text-center">

  </section>

  <!-- Footer -->
  <footer id="footer" class="navbar-inverse">

      <p class="navbar-text"><a href="#">Terms and Conditions</a> | <a data-toggle="modal"href="#creditations">Creditations</a></p>
    </div>
  </footer>

的CSS：

li {
  list-style-type: none; }

section {
  min-height: 500px; }

h1 {
  font-size: 25px; }

u {
  border-bottom: 1px dotted #000;
  text-decoration: none; }

footer p {
  position: absolute; }

#logo {
  height: 60px;
  width: 140px;
  position: relative;
  bottom: 20px;
  right: 10px;
  padding-left: 20px; }

.nav {
  padding-left: 6px; }

.navbar-right {
  padding-right: 30px; }

.navbar-header {
  padding-right: 20px; }

#footer {
  min-height: 0px;
  line-height: 25px;
  height: 50px;
  padding-top: 0;
  padding-right: 100px; }

#footer > .container > p > a {
  color: white; }

.glyphicon-home {
  padding-right: 5px; }

.carousel-control .icon-prev,
.carousel-control .icon-next {
  font-size: 50px; }

#myCarousel {
  padding-top: 50px; }

.text-justify {
  text-align: justify; }

.text-center {
  text-align: center; }

@media only screen and (max-width: 400px) {
  .text-center {
    padding-right: 40px;
    /*require padding */
    padding-left: 40px;
    /*require padding */ } }
#about {
  border: 1px solid black;
  background-color: red; }

#learnMoreButton:hover {
  transition: background-color 200ms ease-out 50ms; }

li > a {
  transition: background-color 200ms ease-out 50ms; }

/*# sourceMappingURL=stylesheet.css.map */

Answer 1

这是因为您在section元素上设置了{{1}}。因此，您的部分将始终具有最小500px高度（在桌面屏幕上，您会看到此部分与我们之间的差距，因为您的产品高度约为150px，在小屏幕上，此部分大约有500px，因此您看不到这个差距）。
