＆＃13;

其余代码在codepen链接上。在我的div上面似乎有一些填充或某些东西。在我使用display: inline-block之前，没有一个。我可以适应每个div的标题，但必须通过设置足够的余量来完成。但是我不想移动灰色区域，我希望它能够存在，因为我试图尽可能地将它居中。 （有更有效的方法吗？我通过计算边距和分割来做到这一点。基本上我希望所有边距都相同（底部，顶部，右边，左边））我想要标题，以及列表稍微有点完美地适应灰色区域。我该怎么办？

Answer 1

h2元素有一个默认的边距。

当您从h2元素中删除上边距时，您将获得所需的结果。

CSS

h2 {
  margin-top: 0;
}

Codepen link

Answer 2

您遇到的问题不是由 padding 引起的，而是 {{1}中的 margin-top } 默认存在的元素。您可以使用以下CSS代码来缓解它：

h2

Codepen：→here。

<强>段：

.content {
  margin-top: 0;
}

h1 {
  color: white;
  font-size: 90px;
  text-align: center;
  width: 950px;
  height: 100px;
  margin: auto;
  margin-top: 20px;
  border-radius: 5px;
  background-color: darkblue;
}

#slogan {
  font-size: 40px;
  text-align: center;
  margin: auto;
  margin-top: -3px;
  font-family: Agency FB;
  width: 940px;
  height: 50px;
  background-color: white;
  border: 5px solid darkblue;
}

#table {
  display: inline-block;
  width: 225px;
  height: 170px;
  margin-top: 59.25px;
  margin-left: 59.25px;
  text-align: left;
  background-color: #c0c0c0;
  color: white;
  border-radius: 5px;
}

.content {
  margin-top:0;
  text-align: center;
  border-radius: 5px;
  background-color: darkblue;
}

ul {
  font-family: Georgia;
  text-decoration: none;
  list-style-type: none;
  padding: 0px;
  margin: 0px;
  margin-top: -10px;
  margin-left: 10px;
}

a {
  text-decoration: none;
  color: white;
}

.div {
  width: 940px;
  height: 525px;
  margin: auto;
  border-radius: 5px;
  background-color: white;
  border: 5px solid darkblue;
  border-top-left-radius: 0px;
  border-top-right-radius: 0px;
}

img {
  width: 25px;
  height: 25px;
  padding-right: 10px;
}

Answer 3

您只需要从内容标题中删除边距即可。您可以使用顶部，左侧，右侧或底部来定位特定边距。在这种情况下，您需要定位h2标签的margin-top。

.content {
    text-align:center;
    border-radius:5px;
    background-color:darkblue;
    margin-top:0; /*This is the added property*/
}
