如何将 div 按钮固定在屏幕右侧？

Question

我有一个 div 按钮，由两块 div 和一个 parent div 组成。该按钮必须位于屏幕的右侧。但它不会在更改屏幕分辨率时保持静止（例如；100%，%75）

parent div css:

.help-parent{
    position: "absolute";
    top:"0px";
}

帮助图标 css :

.help {
    position: absolute;
    color: rgb(243, 77, 0);
     display:inline-block;
    text-align: right;
    top: 50px;
    left: 1490px;
    height: 30px;
    z-index: 11;
    padding-top: 5px;
}

秒 div :

.help-button {
    position: absolute;
    text-align:left;
    top:50px;
    background-color:rgb(243, 77, 0);
    display:inline-block;
    width:200px;
    height:31px;
    z-index: 10;
    left:1500px;
}

将屏幕分辨率 %100 更改为 %75 时向左滑动；

我希望按钮保持在固定位置。我怎样才能做到这一点？

我根据@greg_的回答修改了。我从 child divs 中删除了 absolute 并且我添加了 vw 95 和 absolute position 到 parent div。 div 固定为右。在我从 child 中删除 absoulute 之后，divs 彼此分开。我如何合并 child divs ?

Answer 1

我相信，left你要多考虑一下。

Answer 2

child div 应与 parent 一起移动，因此删除 child div 的任何位置 css。对于 parent，请尝试使用视口单位 (vh, vw)。这将确保位置始终相对于视口。 Parent div css:

.help-parent {
position: absolute;
top:0;
left:95vw;
}

1vw = 视口宽度的 1%，因此 95vw 将使您的按钮保持在视口宽度的 95%（最右侧）。更多信息：https://developer.mozilla.org/en-US/docs/Web/CSS/length

Answer 3

您添加了一个固定的 left 值。使用 right 或 left: 90xw

Answer 4

您忘记了 position 的重要性以及它与父元素相关的作用。

如果父级 position 也设置为 relative 或 fixed 等，则绝对仅适用于父级

我在下面举了一个例子来说明它是如何工作的。

/* container to set a base line */
.menu-bar {
  position: fixed; /* fixed to the viewport */
  height: 50px;
  width: 100vw;
  top: 0; /* set to top of viewport */
  overflow: hidden;
  /* not question related styling */
  background: #fff;
}

/* set elements to stick within it's parent element */

.stick {
  position: absolute; /* stick to current parent */
  height: 50px;
  width: 100px;
  top: 0; /* stick to top of parent */
  /* not question related styling */
  background: red;
}

.left {
  left: 0;
  margin-left: -50px; /* negative to go beyond the viewport */
  /* not question related styling */
  text-align: right;
}

.right {
  right: 0;
  margin-right: -50px; /* negative to go beyond the viewport */
}

.left:hover {
 margin-left: 0;
}

.right:hover {
 margin-right: 0;
}
