CSS:x轴上的固定位置但不是y？

Question

有没有办法只在x轴上固定一个位置？因此,当用户向上滚动时,div标签会向上滚动,但不能左右滚动？

Answer 1

它也是一种使用脚本的简单技术.您也可以在这里查看演示.

JQuery的

$(window).scroll(function(){
    $('#header').css({
        'left': $(this).scrollLeft() + 15 
         //Why this 15, because in the CSS, we have set left 15, so as we scroll, we would want this to remain at 15px left
    });
});

CSS

#header {
    top: 15px;
    left: 15px;
    position: absolute;
}

更新信用:@ PierredeLESPINAY

如评论所述,使脚本支持css中的更改,而无需在脚本中重新编码它们.您可以使用以下内容.

var leftOffset = parseInt($("#header").css('left')); //Grab the left position left first
$(window).scroll(function(){
    $('#header').css({
        'left': $(this).scrollLeft() + leftOffset //Use it later
    });
});

演示 :)

这是一个旧线程,但CSS3有一个解决方案.

position: sticky;

如果您的块最初定位为静态,则可能需要尝试此操作

$(window).on('scroll', function () {

  var $w = $(window);
  $('.position-fixed-x').css('left', $w.scrollLeft());
  $('.position-fixed-y').css('top', $w.scrollTop());

});

.container {
  width: 1000px;
}

.position-fixed-x {
  position: relative; 
}

.position-fixed-y {
  position: relative;
}

.blue-box {
  background:blue;
  width: 50px;
  height: 50px;
}

.red-box {
  background: red;
  width: 50px;
  height: 50px;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container">

<div class="position-fixed-y red-box">
  
</div>

The pattern of base pairs in the DNA double helix encodes the instructions for building the proteins necessary to construct an entire organism. DNA, or deoxyribonucleic acid, is found within most cells of an organism, and most organisms have their own unique DNA code. One exception to this is cloned organisms, which have the same exact DNA code as their parents do.

<div class="position-fixed-x blue-box">
  
</div>

DNA strands are composed of millions of sub-units, called nucleotides. Each nucleotide contains a 5-carbon sugar, a phosphate group and a nitrogen base. There are four different variations of the nitrogen base group, responsible for all of the variation between two different DNA strands. The four different variations are called adenine, guanine, cytosine and thymine, but they are typically abbreviated and only referred to by their first letter. The sequence of these different nitrogen bases makes up the code of the DNA.

The DNA strand splits in two, and forms two different DNA strands during cell replication. However, sometimes this process is not perfect, and mistakes occur. These mistakes may change the way an organism is constructed or functions. When this happens, it is called a mutation. These mutations can be helpful or harmful, and they are usually passed on to the organism’s offspring.
  
 The traits of a living thing depend on the complex mixture of interacting components inside it. Proteins do much of the chemical work inside cells, so they largely determine what those traits are. But those proteins owe their existence to the DNA (deoxyribonucleic acid), so that is where we must look for the answer.
The easiest way to understand how DNA is organized is to start with its basic building blocks. DNA consists of four different sugars that interact with each other in specific ways. These four sugars are called nucleotide bases and have the names adenine (A), thymine (T), cytosine (C) and guanine (G). Think of these four bases as letters in an alphabet, the alphabet of life!
If we hook up these nucleotides into a sequence--for example, GATCATCCG--we now have a little piece of DNA, or a very short word. A much longer piece of DNA can therefore be the equivalent of different words connected to make a sentence, or gene, that describes how to build a protein. And a still longer piece of DNA could contain information about when that protein should be made. All the DNA in a cell gives us enough words and sentences to serve as a master description or blueprint for a human (or an animal, a plant, or a microorganism).
Of course, the details are a little more complicated than that! In practice, active stretches of DNA must be copied as a similar message molecule called RNA. The words in the RNA then need to be "read" to produce the proteins, which are themselves stretches of words made up of a different alphabet, the amino acid alphabet. Nobel laureates Linus Pauling, who discerned the structure of proteins, and James Watson and Francis Crick, who later deciphered the helical structure of DNA, helped us to understand this "Central Dogma" of heredity--that the DNA code turns into an RNA message that has the ability to organize 20 amino acids into a complex protein: DNA -> RNA -> Protein.
To understand how this all comes together, consider the trait for blue eyes. DNA for a blue-eyes gene is copied as a blue-eyes RNA message. That message is then translated into the blue protein pigments found in the cells of the eye. For every trait we have--eye color, skin color and so on--there is a gene or group of genes that controls the trait by producing first the message and then the protein. Sperm cells and eggs cells are specialized to carry DNA in such a way that, at fertilization, a new individual with traits from both its mother and father is created.

不,纯CSS不可能.这种定位修复了视口中的元素.我建议只需将元素固定到视口的一侧(即顶部,底部,左侧或右侧),这样它就不会干扰其他内容.

现在，移动设备已占互联网市场的70％以上，您可以创建智能且响应迅速的产品。

您可以仅使用CSS来非常轻松地创建此容器，对容器使用overflow-x：scroll，对另一个容器使用overflow-y：scroll。您可以轻松地将容器元素的宽度：100vw和高度：100vh定位。

在示例上单击鼠标中键以对其进行测试。在移动设备上效果最佳，因为您看不到滚动条。

body{max-width:100%}
*{box-sizing:border-box;}
.container{background:#ddd;overflow-y:scroll;width:500px;max-height:100vh;}
.header{background: pink;}
.body{background: teal;padding:20px;min-width: 100%;overflow:scroll;overflow-y:hidden;min-height:300px;}
.body >div{min-width:800px;}

<body>
  <div class="container">
    <div class="header">
       Button 1 > Button 2 > Button 3
    </div>
    <div class="body">
      <div>

听起来您需要使用position:fixed，然后将顶部位置设置为百分比，并将左侧或右侧位置设置为固定单位。
