我正在尝试复制BBC新闻网站，我有这个奇怪的样式问题。 Here is the image.
我总是在两个div之间得到这个差距。 这是我使用的代码。不知道我应该如何摆脱那个空间。尝试将边距和填充设置为0，但这没有用。
以下是代码：
body{
margin: 0;
padding: 0;
font-family: Helvetica, Arial, sans-serif;
}
#topbar{
height: 40px;
width: 1000px;
margin: 0 auto;
background-color: #FFFFFF;
}
#logo{
float: left;
margin-top: 8px;
margin-right: 8px;
}
.topbarsections{
float:left;
border-left: 1px #CCCCCC solid;
height: 100%;
}
#signin-image{
float: left;
width: 30px;
margin-top: 7px;
margin-left: 8px;
}
#signin-text{
float: left;
font-weight: bold;
font-size: 90%;

position: relative;
top: 13px;
padding-right: 80px;
}
.topbar-menu{

答案 0 :(得分：1)
如果通过＆＃34; gap＆＃34;你的意思是标题上方的空格＆＃34;技术＆＃34;，@ Olivier Krull是对的：它是h2标题的默认边距。
您只需添加此CSS规则即可将其设置为零：
#main-article > h2:first-child {
margin-top: 0;
}
