Css Bootstrap 3模式垂直位置中心
这是一个由两部分组成的问题:Css Bootstrap 3模式垂直位置中心,css,twitter-bootstrap,modal-dialog,center,Css,Twitter Bootstrap,Modal Dialog,Center,这是一个由两部分组成的问题: 当您不知道模态的确切高度时,如何将模态垂直放置在中心 模态是否可以居中并在模态主体中具有overflow:auto,但前提是模态超过屏幕高度 我试过使用这个: .modal-dialog { height: 80% !important; padding-top:10%; } .modal-content { height: 100% !important; overflow:visible; } .modal-body { height:
.modal-dialog {
height: 80% !important;
padding-top:10%;
}
.modal-content {
height: 100% !important;
overflow:visible;
}
.modal-body {
height: 80%;
overflow: auto;
}
当内容比垂直屏幕大得多时,这会给我提供所需的结果,但对于较小的模式内容,它几乎不可用。尝试以下方法:
.popup__overlay {
position: fixed;
left: 0;
top: 0;
width: 100%;
height: 100%;
z-index: 999;
text-align: center
}
.popup {
display: inline-block;
vertical-align: middle
}
您可能想查看这个div绝对居中的方法集合:我想出了一个纯css解决方案!虽然它是css3,这意味着ie8或更低版本不受支持,但除此之外,它已经在ios、android、ie9+、chrome、firefox、桌面safari上进行了测试和工作 我正在使用以下css:
.modal-dialog {
position:absolute;
top:50% !important;
transform: translate(0, -50%) !important;
-ms-transform: translate(0, -50%) !important;
-webkit-transform: translate(0, -50%) !important;
margin:auto 5%;
width:90%;
height:80%;
}
.modal-content {
min-height:100%;
position:absolute;
top:0;
bottom:0;
left:0;
right:0;
}
.modal-body {
position:absolute;
top:45px; /** height of header **/
bottom:45px; /** height of footer **/
left:0;
right:0;
overflow-y:auto;
}
.modal-footer {
position:absolute;
bottom:0;
left:0;
right:0;
}
display:table
这是一把小提琴。
…选择此选项作为正确答案,因为在出现多个模态的情况下,没有额外繁重的javascript会使浏览器崩溃。我的解决方案
.modal-dialog-center {
margin-top: 25%;
}
<div id="waitForm" class="modal">
<div class="modal-dialog modal-dialog-center">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 id="headerBlock" class="modal-title"></h4>
</div>
<div class="modal-body">
<span id="bodyBlock"></span>
<br/>
<p style="text-align: center">
<img src="@Url.Content("~/Content/images/progress-loader.gif")" alt="progress"/>
</p>
</div>
</div>
</div>
</div>
.modal对话框中心{
利润率最高:25%;
}

在我的例子中,我所做的就是在css中设置顶部,知道模态的高度
代码>
在我的css中,我设置了
#myModal{
height: 400px;
top: calc(50% - 200px) !important;
}
我已经从下面的链接下载了bootstrap3对话框,并修改了bootstrap-dialog.js中的open函数
代码
open: function () {
!this.isRealized() && this.realize();
this.updateClosable();
//Custom To Vertically centering Bootstrap
var $mymodal = this.getModal();
$mymodal = $mymodal.append('<table border="0" cellpadding="0" cellspacing="0" width="100%" height="100%"><tr><td align="center" valign="middle" class="centerModal"></td></tr></table>');
$mymodal = $mymodal.find(".modal-dialog").appendTo($mymodal.find(".centerModal"));
//END
this.getModal().modal('show');
return this;
}
1。当您不知道模态的确切高度时,如何将模态垂直放置在中心?
要在不声明高度的情况下绝对居中引导3模式,首先需要通过将以下内容添加到样式表来覆盖引导CSS:
.modal-dialog-center { /* Edited classname 10/03/2014 */
margin: 0;
position: absolute;
top: 50%;
left: 50%;
}
.modal-body {
overflow-y: auto;
}
.modal-footer {
margin-top: 0;
}
这将使模式对话框位于窗口中心的左上角
我们必须添加此媒体查询,否则在小型设备上留下的模式边距是错误的:
@media (max-width: 767px) {
.modal-dialog-center { /* Edited classname 10/03/2014 */
width: 100%;
}
}
现在我们需要用JavaScript调整它的位置。为此,我们给元素一个负的顶部和左边缘,等于其高度和宽度的一半。在本例中,我们将使用jQuery,因为它可以用于引导
$('.modal').on('shown.bs.modal', function() {
$(this).find('.modal-dialog').css({
'margin-top': function () {
return -($(this).outerHeight() / 2);
},
'margin-left': function () {
return -($(this).outerWidth() / 2);
}
});
});
更新(2015年10月1日):
加上。归功于
注意负的边距,对吗?这将删除内联块添加的空间。该空间导致模式跳转到页面底部@media width<768px
2。模态是否可以居中并在模态正文中显示overflow:auto,但前提是模态超出屏幕高度?
这可以通过为模态实体提供overflow-y:auto和max height来实现。这需要更多的工作才能让它正常工作。首先将其添加到样式表中:
.modal-dialog-center { /* Edited classname 10/03/2014 */
margin: 0;
position: absolute;
top: 50%;
left: 50%;
}
.modal-body {
overflow-y: auto;
}
.modal-footer {
margin-top: 0;
}
我们将再次使用jQuery获取窗口高度,并首先设置模式内容的最大高度。然后我们必须设置模态主体的最大高度,方法是用模态页眉和模态页脚减去模态内容:
$('.modal').on('shown.bs.modal', function() {
var contentHeight = $(window).height() - 60;
var headerHeight = $(this).find('.modal-header').outerHeight() || 2;
var footerHeight = $(this).find('.modal-footer').outerHeight() || 2;
$(this).find('.modal-content').css({
'max-height': function () {
return contentHeight;
}
});
$(this).find('.modal-body').css({
'max-height': function () {
return (contentHeight - (headerHeight + footerHeight));
}
});
$(this).find('.modal-dialog').css({
'margin-top': function () {
return -($(this).outerHeight() / 2);
},
'margin-left': function () {
return -($(this).outerWidth() / 2);
}
});
});
您可以在这里找到Bootstrap 3.0.3的工作演示:
编辑:我建议使用更新版本,以获得更具响应性的解决方案:
更新(30/11/2015):
函数setModalMaxHeight(元素){
此.$element=$(element);
this.$content=this.$element.find('.modal content');
var borderWidth=this.$content.outerHeight()-this.$content.innerHeight();
var dialogMargin=$(窗口).width()<768?20:60;
var contentHeight=$(窗口).height()-(对话框边距+边框宽度);
var headerHeight=this.$element.find('.modal header').outerHeight()| | 0;
var footerHeight=this.$element.find('.modal footer').outerHeight()| | 0;
var maxHeight=内容高度-(页眉高度+页脚高度);
这是$content.css({
“溢出”:“隐藏”
});
这是$element
.find('.modal body').css({
“最大高度”:最大高度,
“溢出-y”:“自动”
});
}
$('.modal').on('show.bs.modal',function(){
$(this.show();
setModalMaxHeight(这个);
});
$(窗口)。调整大小(函数(){
如果($('.modal.in').length!=0){
setModalMaxHeight($('.modal.in'));
}
});
(通过上述编辑于2015年11月30日更新)考虑使用此处的引导模式插件-
这个插件将把你所有的模态集中起来,这是我写的最通用的解决方案。Dynamicly使用对话框高度进行计算。(下一步可能是在调整窗口大小时重新计算对话框的高度。)
JSfiddle:
//在文档准备就绪时初始化
jQuery(文档).ready(函数($){
"严格使用",;
//中心情态动词
//第一阶段-存储每个对话框的高度
$('.modal')。每个(函数(){
var t=$(此),
d=t.find('.modal dialog'),
fadeClass=(t.is('.fade')?'fade':'';
//渲染对话框
t、 removeClass('fade')
.addClass(“不可见”)
.css(“显示”、“块”);
//读取和存储对话框高度
d、 数据('height',d.height());
//再次隐藏对话框
t、 css('显示','')
.removeClass(“不可见”)
.addClass(fadeClass);
});
//第二阶段-在每次对话框显示时设置页边距顶部
$('.modal').on('show.bs.modal',函数(){
var t=$(此),
d=t.find('.modal dialog'),
dh=d.数据(“高度”),
w=$(窗口).width(),
h=$(窗口).height();
//如果是桌面,则对话框低于视口(&D)
//(设置自己的值)
如果(w>380&(dh+60)
及
function setModalMaxHeight(element) {
this.$element = $(element);
this.$content = this.$element.find('.modal-content');
var borderWidth = this.$content.outerHeight() - this.$content.innerHeight();
var dialogMargin = $(window).width() < 768 ? 20 : 60;
var contentHeight = $(window).height() - (dialogMargin + borderWidth);
var headerHeight = this.$element.find('.modal-header').outerHeight() || 0;
var footerHeight = this.$element.find('.modal-footer').outerHeight() || 0;
var maxHeight = contentHeight - (headerHeight + footerHeight);
this.$content.css({
'overflow': 'hidden'
});
this.$element
.find('.modal-body').css({
'max-height': maxHeight,
'overflow-y': 'auto'
});
}
$('.modal').on('show.bs.modal', function() {
$(this).show();
setModalMaxHeight(this);
});
$(window).resize(function() {
if ($('.modal.in').length != 0) {
setModalMaxHeight($('.modal.in'));
}
});
// initialise on document ready
jQuery(document).ready(function ($) {
'use strict';
// CENTERED MODALS
// phase one - store every dialog's height
$('.modal').each(function () {
var t = $(this),
d = t.find('.modal-dialog'),
fadeClass = (t.is('.fade') ? 'fade' : '');
// render dialog
t.removeClass('fade')
.addClass('invisible')
.css('display', 'block');
// read and store dialog height
d.data('height', d.height());
// hide dialog again
t.css('display', '')
.removeClass('invisible')
.addClass(fadeClass);
});
// phase two - set margin-top on every dialog show
$('.modal').on('show.bs.modal', function () {
var t = $(this),
d = t.find('.modal-dialog'),
dh = d.data('height'),
w = $(window).width(),
h = $(window).height();
// if it is desktop & dialog is lower than viewport
// (set your own values)
if (w > 380 && (dh + 60) < h) {
d.css('margin-top', Math.round(0.96 * (h - dh) / 2));
} else {
d.css('margin-top', '');
