奇怪:HTML顶部的空白

标签: html css html5

我遇到了一个我正在处理的网站的问题,因为显然没有理由,文件顶部会出现空白(右边1 px)。我已将margin: 0; padding:0;添加到<body><html>,但无济于事。

当我在Chrome DevTools中检查过它时,我似乎找不到任何导致它的元素。如果我没记错的话,当没有CSS存在时也会出现。 HTML和CSS如下所示。

4 个答案:

答案 0 :(得分:1)

之前发生在我身上。我老实说我正在寻找一个更好的解决方案,但它让我非常烦恼我最终在html上使用绝对定位(或者可能是正文)并将顶部设置为0.我知道这是一个快速修复,可能不是你的意思寻找。

所以你可以尝试以下方法:

html, body {
    position: absolute;
    top: 0;
}

至少应该解决这个问题。

答案 1 :(得分:0)

一位朋友联系我并说这是WebKit的错。如果您检查标题中的H1,它会添加我认为0.83em与

的h1
:-webkit-any(article,aside,nav,section) :-webkit-any(article,aside,nav,section) h1

它也与H2和其他元素相同。我不知道为什么他们会这样做。他们的假设是什么?对我来说似乎很愚蠢,但我不是专家。无论如何,这是h1s的修复:

:-webkit-any(article,aside,nav,section) :-webkit-any(article,aside,nav,section) h1 {
        margin: 0;
}

您是否考虑过使用CSS重置表?我发现它消除了大部分这些挫折,并给你一个空白的状态来工作。

我倾向于使用:

答案 3 :(得分:0)

当我浮动元素并且没有正确使用clearfix时,我遇到了完全相同的问题。检查是否对包含带有float:left或float:right属性的子元素的每个元素使用clearfix。

例如:

<header class="clearfix">
   <nav class="flo-l">
      <a href="#services" class="ed">Services</a>
      <a href="#contact" class="ed">Email</a>
   </nav>
   <h1 class="lava">Hillside Insurance Agency</h1> 
   <nav class="flo-r">
      <a href="#contact" class="ed">Phone</a>
      <a href="#about" class="ed">About</a>
   </nav>
</header>

检查整个文档中的所有元素。我为我工作。
