css - 相对内的绝对定位

Question

我正在使用 100% 宽度相对定位，但需要一个绝对定位的子 div 或 span 来容纳 jquery 图像 slider 。

布局

------宽度100%--------

| img1 | slider | img2 |

当前， slider 跨度不像其他对象那样内联定位和重叠

我目前拥有的:

Answer 1

我已经为查看器添加了一个包装器，并使用 html 注释标签删除了外部图像和幻灯片查看器之间的额外间距(这比设置 font-size:0 更好)。我已经调整了 JS，以便过渡有效。我还清理并减少了所需的 CSS 数量。

HTML

<div class="picture-container">
    <img src="http://www.image-and-text.com/pictures/whiskey_with_ice.jpg" /><!--
        --><div class="viewer">
        <img src="http://images.printsplace.co.uk/Content/Images/Products/46576/43569/Image_of_M101_1.jpg" class="active" />
        <img src="http://i.bosity.com/clothes_cache/261/12002348/3480000011312473207_12002348_1_image.jpg" />
        <img src="http://lokeshdhakar.com/projects/lightbox2/images/examples/image-6.jpg" /> 
        </div><!--
    --><img src="http://www.image-and-text.com/pictures/whiskey_with_ice.jpg" />
</div>

CSS:

* {margin:0;padding:0}
.picture-container > img {display:inline-block;width:25%;}
.viewer {display:inline-block;position:relative;width:50%;vertical-align:top;}
.viewer img {position:absolute;width:100%;}

JS

function slideSwitch() {
  var transitionDuration = 1000;
    var active = $('.viewer img.active');
    var next = $('.viewer img:first').insertAfter(active);
    active.removeClass('active').fadeOut(transitionDuration);
    next.addClass('active').hide().fadeIn(transitionDuration);
}
$(document).ready(function(){
    $('.viewer img.active').insertAfter('.viewer img:last');
    setInterval("slideSwitch()", 4000);
});
