很明显，我对html和CSS很新。我最近接受了它们（与django一起），并且一直在使用我自己的代码并从各种教程中借用片段。让你看到下面看到的弗兰肯斯坦的一个缺点是，神秘的异常往往会在清澈的蓝天中形成。最新和令人困惑的是我的一些div（顶部的两个）之间的一个微小的空白区域。我一直在寻找罪魁祸首，但却没有取得什么成功。如果有人可以看一看并提供建议，那就太棒了。
这是我的Html：

具有属性inline-block的元素的行为就像它们是内联的（因此是名称），因此遇到的任何空格都将被视为空格。例如：
<div></div><div></div>
将以不同的方式呈现
<div></div>
<div></div>
您可以使用HTML解决此问题，如下所示：
将所有元素放在同一行，即
<div>
// CONTENT
</div><div>
// CONTENT
</div><div>
// CONTENT
</div>
或使用HTML注释删除空格
<div>
//CONTENT
</div><!--
--><div>
//CONTENT
</div>
您可以使用CSS解决此问题，如下所示：
在父项上设置属性font-size: 0，即
parent {
display: inline-block;
font-size: 0
}
parent * {
font-size: 12px
}
或在父项上设置属性zoom: 1，即
parent {
display: inline-block;
zoom: 1
}

那么你好，
我在早期作为网络开发者也遇到过这个问题。问题是有一个字符（空格，每行上有很多空格 - 标记缩进），它被渲染。您可以通过设置：
来摆脱这个问题body {
font-size: 0px;
}
* {
font-size: inherit;
}
然后为显示文本所需的每个元素设置font-size css属性。
希望它有所帮助;）
