Question

Three div panels:-
1) (div-B) one div with max-width = 500px and min-width=400px should always on 
    the center of all browsers.
2) (div-A) one div should show and hide on the left of (div-B) having min-width 
   = 200px and max-width= 300px;
3) (div-C) one div should show and hide on the right of (div-B) having min-width 
   = 200px and max-width= 300px;

div-A和div-C的显示和隐藏方式应使其不会从其位置移开div-B，但是，它可以达到可用的最大宽度和最小宽度。 div-B应该始终位于所有浏览器的中心。

页面布局：-

Header
<--Left button here                                       right button here-->
to open div-A panel                                       to open div-c panel
(basically a dropdown)                                  (basically a dropdown)


         Left Panel <---20px---> Center Panel <---20px---> Right Panel   
         (div-A)                  (div-B)                     (div-C)    

1) (div-A && div-B), (div-B && div-C) having margin 20px in between always.
   div-A should grow towards left and div-c should grow towards right relative to div-B(min-width and 
   max-width availability).
2) div-B should not move to right or left when div-A and div-C should hide. 
 But div-B should grow towards its left or right keeping div-B fixed to 
  center of browser window and tries to achieve its max-width(keeping center 
 axis fixed) if space available towards right or left.

<header>
//show hide button for div-A
<div class="div-A-button">Dropdown button A</div>
//show hide button for div-C
<div class="div-C-button">Dropdown button C</div>
</header>

<main>
<div class="panel div-A">Panel A </div>  //show and hide using div-A-button
<div class="panel div-B">Panel B </div>  //fixed always show
<div class="panel div-C">Panel C </div>  //show and hide using div-C-button
</main>

Answer 1

您可以使用CSS网格。我想我已经了解了您的布局。让我知道下面的例子是否正确。

main {
  border: 1px solid;
  display: grid;
  grid-template-columns: minmax(200px, 300px) minmax(400px, 500px) minmax(200px, 300px);
  grid-gap: 20px;
  justify-content: center;
}

main>div {
  background: yellow;
  text-align: center;
  padding: 1em;
}

.div-B {
  grid-column: 2;
}

<main>
  <div class="panel div-A">Panel A </div>
  <div class="panel div-B">Panel B </div>
  <div class="panel div-C">Panel C </div>
</main>

Answer 2

可以使用flex：

<!DOCTYPE html>
<html>
<head>
  <style>
      .container {
          display: flex;
          flex-direction: row;
          justify-content: center;
          align-items: center;
          flex: 1;
          overflow: hidden;
      }

      .classA {
          display: flex;
          flex-direction: row;
          justify-content: center;
          align-items: center;
          min-width: 200px;
          max-width: 300px;
          height: 200px;
          width: 300px;
          background-color: red;
      }
      .classB {
          display: flex;
          flex-direction: row;
          justify-content: center;
          align-items: center;
          flex: 1;
          min-width: 400px;
          max-width: 500px;
          width: 500px;
          height: 200px;
          margin-left: 20px;
          margin-right: 20px;
          background-color: yellow;
      } 
      .classC {
          display: flex;
          flex-direction: row;
          justify-content: center;
          align-items: center;
          min-width: 200px;
          max-width: 300px;
          height: 200px;
          width: 300px;
          background-color: blue;
      } 
      </style>
</head>
<body>
  <div class="container">
    <div class="classA">A</div>
    <div class="classB">B</div>
    <div class="classC">C</div>
  </div>
</body>
</html>

Answer 3

据我所知，您的问题是容器private static String getXSIType(String fieldType) { String result=new String(); switch (fieldType) { case "_checkBox": result="platformCore:BooleanCustomFieldRef"; break; case "_integerNumber": result="platformCore:LongCustomFieldRef"; break; case "_multipleSelect": result="platformCore:MultiSelectCustomFieldRef"; break; case "_currency": case "_decimalNumber": case "_percent": result="platformCore:DoubleCustomFieldRef"; break; case "_document": case "_listRecord": case "_image": result="platformCore:SelectCustomFieldRef"; break; case "_date": case "_datetime": case "_timeOfDay": result="platformCore:DateCustomFieldRef"; break; case "_freeFormText": case "_eMailAddress": case "_help": case "_hyperlink": case "_inlineText": case "_longText": case "_password": case "_phoneNumber": case "_richText": case "_textArea": result="platformCore:StringCustomFieldRef"; break; default: result="platformCore:StringCustomFieldRef"; break; } return result; }应该始终居中，而不考虑div-B或div-A。我改变了两件事：

我将样式更新为flexbox，到目前为止，flexbox具有非常好的浏览器支持。
将隐藏类从div-B更改为display:block，因此可用空间仍被阻止为visibility:hidden
为了更好地理解视觉效果，我在div-B容器中添加了红色边框

全屏查看示例，以查看.panel是灵活的

.div-B

$(".pull-left").click(function() {
  $(".div-A").toggleClass("hide")
});

$(".pull-right").click(function() {
  $(".div-C").toggleClass("hide")
});

p {
  font-family: Lato;
}

.show {
  display: block;
}

.hide {
  visibility: hidden;
}

header {
  height: 40px;
}

div.pull-left {
  float: left;
  width: 100px;
  display: block;
  color: red;
  text-align: center;
  border: 1px solid #ccc;
}

div.pull-right {
  float: right;
  width: 100px;
  text-align: center;
  border: 1px solid #ccc;
}

.row {
  display: flex;
  justify-content: space-between;
  align-items: center;
}

.row .panel {
  border: 1px solid red;
  flex: 0 0 200px;
}

.row .panel.div-B {
  flex: 1;
}

Answer 4

使用CSS网格，并在父元素上使用实用工具类为所有可能的情况定义ffmpeg属性。使path而不是createWriteStream居中。下面的代码段应该可以使用，代码语法与Node.js版本略有不同。查看整页。

grid-column

main

div

Answer 5

您可以使用minmax() CSS函数来固定宽度，并隐藏div以使中心div保持在页面中心，请使用css的visibility : hidden属性将其从页面中隐藏，但会保持它在DOM中显示，因此如果侧面的两个div中的任何一个在点击时隐藏，则中心div不会受到影响

working code

<div id="container">
    <div (click)="visibility = !visibility" [ngClass]="{'hide' : visibility}">
     <select style="width :-webkit-fill-available;"></select>
      at most 300 pixels
    </div>
    <div>20px</div> //separator
    <div>
    <div style="position:absolute">
      Item with 400 to max 500px width
    </div>
  </div>
    <div>20px</div>    //separator
    <div  (click)="visibility1 = !visibility1" [ngClass]="{'hide' : visibility}">
        at most 300 pixels.
    </div>
  </div>

css

#container {
  display: grid;
  grid-template-columns: minmax(200px, 300px) 20px minmax(400px, 500px) 20px minmax(200px, 300px);
  box-sizing: border-box;
  height: 200px;
  background-color: #8cffa0;
  width: 100%;
}

#container > div {
  background-color: #8ca0ff;
  border: 1px dotted red;
 }
 .hide {
   visibility: hidden;
 }

我已经简单地提出了您的请求，请检查下面的代码段。希望它是您所要求的。

var divchecker = 0;

$('.pull-left').click(function() {
    //you are hiding the Div A now
    divchecker = divchecker+1;
    $('.div-A').hide();
    $('.pull-left2').show();
    $('.pull-left').hide();
    $('.gridsection').css('grid-template-columns', '70% auto');
    if (divchecker == 2){
      $('.gridsection').css('grid-template-columns', '100%');
    }
});
$('.pull-right').click(function() {
    //you are hiding the Div C now
    divchecker = divchecker+1;
    $('.div-C').hide();
    $('.pull-right2').show();
    $('.pull-right').hide();
    $('.gridsection').css('grid-template-columns', 'auto 70%');
    if (divchecker == 2){

Answer 7

您是否听说过Bootstrap Framework。我在这里为您提供一个示例，说明我将如何使用此框架针对您的需求进行响应式（跨浏览器）布局。我不能严格匹配的唯一要求是下一个：

三个div面板： 1）（div-B），一个max-width = 500px和min-width = 400px的div应该始终位于所有浏览器的中心。 2）（div-A）：一个分区应显示并隐藏在（div-B）的左侧，其最小宽度为200px，最大宽度为300px； 3）（div-C），一个分区应显示并隐藏在（div-B）的右侧，其最小宽度= 200px，最大宽度= 300px;

Bootstrap 的列网格系统（将屏幕宽度划分为12列）会自动管理列的宽度，以使站点能够响应各种类型的屏幕，所以我不知道是否有可能与您的最大/最小像素宽度值匹配，但是您可以将总列的百分比分配给具有类似方法的三个元素。其余的一切都很好。您可以检查下一个示例。希望对您有帮助。

$(document).ready(function()
{
    $("#btnToggleA").click(function()
    {
        $(".div-A").slideToggle();
    });
    
    $("#btnToggleC").click(function()
    {
        $(".div-C").slideToggle();
    });
});

.margin-20px
{
    margin: 0px 20px;
}

Answer 8

您不能使用<div>定位将元素放置在relative中，因为这样，您正在设置UI来将每个元素排列在前一个元素的旁边。因此，我将最终使用absbolute定位（如果您不希望这些元素滚动，请使用fixed定位。）

要将元素向左对齐：

#element {
    position: absolute;
    left: 0;
}

要将元素与中心对齐：

#element {
    position: absolute;
    left: 50%;
    transform: translateX(-50%);
}

要将元素向右对齐：

#element {
    position: absolute;
    right: 0;
}

要居中放置元素，我想出了一个奇怪但可行的解决方案：将元素的left放在父元素的中心（通过设置left: 50%），然后将元素的水平方向平移半角（transform: translateX(-50%)）。注意，这实际上是可行的，因为百分比在trasform之外的任何属性中都是相对于父级的，相对于元素本身。

Answer 9

这里有很多关于如何自己制作CSS的好的答案，但是复杂的框架样式表却难以维护。考虑使用框架。

Skeleton是您使用案例的首选。

<link rel="stylesheet" href="http://getskeleton.com/dist/css/normalize.css">
<link rel="stylesheet" href="http://getskeleton.com/dist/css/skeleton.css">
<!-- .u-pull-* will float content left/right -->
<button class="u-pull-left">Button A</button>
<button class="u-pull-right">Button C</button>
<!-- .container is a centered responsive wrapper -->
<div class="container">
  <div class="row">
    <div class="four columns">Panel A</div>
    <div class="four columns">Panel B</div>
    <div class="four columns">Panel C</div>
  </div>
</div>

Answer 10

使用flex很容易。

.parentDiv{
    display: flex;
}
.childDiv{
    margin: auto;
}

div在任何浏览器（跨浏览器）中居中和居中的位置
