如何使背景无限地沿X方向扩展



我现在有一个标头，其灰色背景的宽度为100％，最大宽度为1000px。我有一个单独的DIV，在实际的标头div后面具有绝对位置，该部门当前是灰色背景，因此灰色可以超过1000px的限制。我希望这种灰色背景扩展到屏幕上的大小，目前正在这样做，但是我遇到的问题是，如果用户必须在所有灰色背景上滚动，则宽度为100％浏览器，所以我在其他地方留下了白色背景。我可以做什么，即使水平滚动也是屏幕的完整宽度？

这是一个jsfiddle：https：//jsfiddle.net/mb1brnma/1/

小提琴中的内容有点混乱，但是它确实代表了问题，如果您向右滚动，则背景不会完全扩展到右边。

好吧，所以，在您的小提琴中努力，我们可以看到问题不是背景颜色不扩展到页面宽度的100％页脚中的元素总计高达100％！因此，获得背景颜色真正占用整个页面的唯一方法是要么a。或，B。(设置具有背景颜色的任何内容，要大于页面宽度的100％(或至少伸出页面的正确界限(。

下面的第一个选项可在方法a上使用；第二种选择是基于方法B；第三种选择只是奖励积分。确保调整两个屏幕的大小，以查看它们在较宽的屏幕尺寸上的比较。

开始，这是我们的问题风格：

footer {
  min-width: 770px;
}
footer #mid {
  min-width: 720px;
}
footer #bottom {
  min-width: 720px;
}

此外，除了<head>之外，您不应在<body>标签之外包含任何元素。那不是有效的HTML。但是在这种情况下，我们实际上不需要<div id="footerTopBG">或<div id="footerBG">，因此我只是在以下示例中对它们进行了评论(除了删除您拥有的body和html标签之外，这是在小提琴中不需要的，或者在堆栈snippet中不需要的(。

选项1：父元素卷轴

第一种方法是在包装元素上设置背景颜色，并确保元素的min-width足够宽以真正包含所有内容。

#footer-container {
  background-color: #9b9b9b;
  min-width: 900px;
  overflow-x: auto;
}

您基本上希望使min-width值尽可能小，以防止在小屏幕上滚动过多。精确值将由您的字体大小和字体面确定，以及子元素的宽度和边距以及其他。

选项一：

footer {
  width: 100%;
  max-width: 900px;
  min-width: 770px;
  float: left;
  height: 310px;

选项2：伪元素

我们可以解决问题的第二种方法是找到内容的实际宽度，并制作一个伪元素，以坐在页脚后面，向右延伸，经过典型的权利，因此背景基本上是超过100％宽。

如果将伪元素添加到最大的容器中，这将是最简单的，因此我将其添加到#footer-container中。

#footer-container {
  background-color: #9b9b9b;
}
#footer-container::after {
  content: '';
  display: block;
  background-color: #9b9b9b;
  width: 793px;
  height: 492px;
  position: absolute;
  top: 0;
  left: 0;
  z-index: -1;
}

就是这样。就像选项One一样，伪元素的精确宽度将取决于您所使用的字体和字体大小，其他元素的宽度和边距/填充物以及其他所有内容。

我们要做的其他事情是要清除fearfix #footer-holder，以便它足够高以包含所有孩子，然后删除footer的明确高度。

选项两个：

footer {
  width: 100%;
  max-width: 900px;
  min-width: 770px;
  float: left;
  /* height: 310px; */
}

选项3：响应式设计

正如我所看到的，症状是您的背景颜色不会一直向右扩展，但是基本的问题是页脚是't响应迅速 - 它不适合浏览器窗口。

要解决此问题，您必须基本上调整样式，以摆脱许多最小宽度，并删除许多不必要的定位和溢出规则，以便在小空间中一切正常流动。然后，您只给页脚颜色，您就可以了，因为您不需要向右滚动。

我会把它留给您，以决定这是否真的是您想做的，但认为我会选择它。

这种方法基本上等于删除与定位和溢出相关的许多样式，然后添加媒体查询以调整某些样式。这是要点：

footer {
  width: 100%;
  max-width: 900px;
  /* min-width: 770px; */
  /* float: left; */
  /* height: 310px; */
}
footer #mid {
  width: 96%;
  margin: 2%;
  max-width: 900px;
  /* float: left; */
  /* position: relative; */
  /* display: inline; */
  /* min-width: 720px; */
}
footer #mid .box {
  /* width: 25%; */
  /* overflow: visible; */
  float: left;
  width: 25%;
}
#footer-container {
  background-color: #9b9b9b;
}
@media all and (max-width: 620px) {
  footer #mid .box:nth-child(odd) {
    clear: left;
  }  
  footer #mid .box {
    width: 48%; /* 96% width of #mid, divided by 2 */
  }
}

请注意，您可能还可以删除其他样式来进一步简化事物，而这些并不是我在下面的摘要中评论的唯一样式，但这应该说明该概念。

结果仍然有些丑陋，随机子弹在周围浮动，但我认为您会在实际网站上纠正这些问题。

由于我在这篇文章上没有字符，这是一个小提琴链接，供您查看。
