让DIV脱离Bootstrap 4容器 [英] Let DIV break out of Bootstrap 4 container

问题描述

我在Bootstra 4中使用了一个容器，将页面内容放在浏览器中间.到目前为止一切正常.

I'm using a container in Bootstra 4 to center the conent of my page in the middle of the browser. So far so normal.

但是我还需要更多.容器内的内容应在左侧弹出，并应扩展到浏览器窗口.但仅在左侧.

But I need something more. The content inside the container should break out on the left side and should grow to the browser-window. But only on the left side.

因为我使用的是光滑滑块，所以不能在容器DIV中的单个对象上使用position:absolute或其他功能.我需要在容器内将整个DIV扩展到左侧.而且我需要一个容器，以使其在右侧与页面的其余部分对齐.

Because I'm using the slick slider, I can't use position:absolute or something else on a single object in the container DIV. I need an whole DIV inside the container to grow to the left side. And I need the container to align it on the right side to the rest of the page.

这是我的实际代码: https://codepen.io/cray_code/pen/erQJey

这就是我所需要的.幻灯片内的图像应向左增大. 蓝色背景是浏览器窗口:

This is what I need. The image inside the slides should grow to the left. The blue background is the browser window:

<div class="bg-dark">
    <div class="container bg-white">
        <div class="slider">
            <div><img src="http://via.placeholder.com/2500x500" class="img-fluid"></div>
            <div><img src="http://via.placeholder.com/2500x500" class="img-fluid"></div>
            <div><img src="http://via.placeholder.com/2500x500" class="img-fluid"></div>
        </div>
    </div>
</div>

<script type="text/javascript">
$(document).ready(function(){
    $('.slider').slick({
        infinite: true,
        dots: true,
        arrows: false,
        draggable: false,
        fade:true,
        autoplay:true,
        autoplaySpeed: 4000,
        speed:1200,
    })
});
</script>

推荐答案

尝试一下( codepen )

HTML:

<div class="bg-dark">
    <div class="container bg-white">
        Content
    </div>
    <div class="slider">
        Slider
    </div>
    <div class="container bg-white">
        Content2
    </div>
</div>

JS:

var width = $(window).width() - (($(window).width() - 
$('.container').outerWidth() ) / 2);
$('.slider').width(width+'px');

$( window ).resize(function() {
    var width = $(window).width() - (($(window).width() - $('.container').outerWidth() ) / 2);
    $('.slider').width(width+'px');
});
