【问题标题】:How to make my div(a relative one) in center of a page and another div go below it, not under it(without make it fixed)如何让我的 div(一个相对的)在页面的中心,另一个 div 在它下面,而不是在它下面(没有让它固定)
【发布时间】:2020-08-18 01:34:15
【问题描述】:

这里我有一个 Div(图中的 div1),我希望它在页面中居中(现在我使用 margin-left 将它强制在我自己电脑的中心位置,但是当其他人打开不同分辨率的屏幕时它,它不在中心。)我已经尝试制作每个relative/fixed/absolute/padding/margin,并在网上搜索了两天,但是div1中的每个部分都崩溃了,或者它不起作用。

同时,我添加了一个文本 div(div2) 并希望它在当前 div(div1) 的下方,它没有在它下方,它隐藏在 div 1 下。我在网上搜索并知道如果在它之前有一个相对/固定位置的 div,它将执行此操作,它将被忽略。所以我也只能对 div 2 使用固定位置。我不希望它出现。而且我还希望它转到页面的中心。

这里的主要问题是我的页面没有固定每个屏幕和中心。

http://circleofallnations.ca/查看示例页面 大圆圈是 div1,其中 5 个部分组成了那个圆圈,这就是为什么 div1 必须是一个相对 div

大圆圈下的文字是div 2。(你可以看到它是短信页面的图片,我在下面的代码中将其更改为文本div。)

Here is the example figure

}
function left2(){
  document.getElementById("left").src = "pictures/left2.png";
}
function left1(){
  document.getElementById("left").src = "pictures/left.png";
}

请帮忙,提前谢谢。

【问题讨论】:

  • 如果您简单地说 margin-left: 15%,您希望容器如何居中? 15% 在不同的屏幕宽度上会有所不同
  • 我尝试过其他方法,例如 text-aligned:center, position: auto...但它们也没有使其居中,所以我将其改回 15% 以使其至少居中我的屏幕。
  • 但这不会使它居中 - 看看使用 flexbox 来居中它。谷歌 flexbox 居中

【解决方案1】:

你好!我认为您应该尝试 margin: auto 属性。首先,从容器中删除 position:relative 和 margin left 属性。然后为您的容器添加宽度或高度(根据您的需要),并为其添加 margin:auto 。这是一个示例代码:

.container {
    display: block;
    width: 500px;
    height: auto;
    margin: auto;
    background-color: black;
}

这肯定会居中对齐。 如果你想让你的 div 转到下一行,只需添加 display: block;财产给它。如果它隐藏在 div1 下,添加 z-index: +1 属性。尝试所有这些修改,如果它解决了您的问题,请告诉我。
