删除两个部分之间的空白区域

Question

我有两个部分：

<section id="achievements"> ... </section>
<section id="services"> ... </section>

他们之间有一个空白区域。虽然我的其他部分情况并非如此。

我没有为这些部分设置任何显示属性，但是它从css文件继承了block的display属性。 （在Chrome中的开发者工具检查时）

我还检查了两个部分的内容，如果由于某种原因出现这些部分的任何内容。情况似乎并非如此。

导致此空白区域的原因是什么？如何删除它？

PS：如果我应该添加更多信息，请告诉我。

PS2：我在本网站上查看的帖子谈到从inline-block元素中删除空格。

Answer 1

您可以尝试使用margin-(right/left/bottom/top):0px

Answer 2

You need to add margin:0; to h2

.upper {margin:0;}

Answer 3

This is the so called collapsed margins

you need to reset the default margin from child h2

Note:

careful img is a self closing tag

Answer 4

Use this: I tested it with the fiddle and it worked.

#services {
  background-color: #e6e6e6;
  height: 1005px;
  margin: 0px;
  padding: 0px;
  float: left;
  clear: none;
}   

or you can use this with divs:

<div id="first_div">
        ...
    </div><div id="second_div">
        ...
    </div>

By putting the divs inline, it removes the space in between elements, because if there is space in between it becomes space in the layout.

Answer 5

That's the margin of you <h2> in the second <section> that's making the gap between your sections.

You may correct it by adding a class to that <h2> and set margin-top: 0; like this:

html:

<h2 class="fix-gap upper bottom_line">Our services</h2>

css:

.fix-gap {
  margin-top: 0;
}

Answer 6

如果遇到这些问题，找到解决方案的最佳方法是Inspect Element。在这里，当您执行此操作时，您将看到有默认边距。因此，要摆脱这种情况，请转到您的CSS文件并设置空白：0;这应该有帮助。
