将鼠标悬停在子元素上时，是否可以删除CSS悬停叠加层的一部分？

Question

我正在使用CSS Image Map Generator伪造图像地图。 当用户将鼠标悬停在外部图像上时，我希望整个图像变暗一点，并在热点周围出现边框。 当他们将鼠标悬停在某个热点上时，我希望该热点不会消失。 这有可能吗？

1. 此图像显示了一个包含产品界面图像的框-为了安全起见，在其中删除了该界面（通过CSS背景图像）。 用户现在没有将鼠标悬停在上面。 没有可见的热点，没有图像叠加。
2. 此图像显示用户将鼠标悬停在“外部”图像的一部分上。 图像具有透明的覆盖层（黑色，不透明度为45％），并且图像地图热点变得可见。
3. 此图像显示用户将鼠标悬停在热点上。

当他们将鼠标悬停在热点上时，我希望将父悬停叠加层的热点区域删除。 那可能吗？ 我将接受任何可证明的解决方案。 Javascript / jQuery很好。

HTML：

<div class="map_image">
          <div class="overlay">
                <a class="map_link" id="map_link_0" href="dp"></a>

CSS：

.map_image { display: block; width: 200px; height: 596px; position: relative; border: 1px solid gray; }

.map_image .map_link { display: block; position: absolute; text-indent: -999em; overflow: hidden; border: 2px solid orange; }

#map_link_0, #map_link_1, #map_link_2, #map_link_3, #map_link_4, #map_link_5 { width: 37px; height: 37px; border-radius: 5px; }

.overlay {  background:rgba(0,0,0,.45); width: 200px; height: 596px; opacity:0; -webkit-transition: opacity .25s ease; -moz-transition: opacity .25s ease;}

.map_image:hover .overlay { opacity:1; }

Answer 1

CBroe的评论是解决问题的方法。 在链接元素上悬停时，将背景设置为原始图像，并放置在适当位置以显示链接区域后面的原始位置（考虑边框大小）。

这是一个带有结果的JSFiddle （显然，发布Codepen是一个nono）。

Answer 2

因此，如果我理解您的问题，您希望在用户将鼠标悬停在特定元素上时删除橙色边框吗？ 如果是这样，您可以通过更新CSS来做到这一点：

.map_image .map_link:hover {
     border: 2px solid transparent;
}

hover启动后，边框仍将为2px并且不可见。

尝试

$(".overlay .map_link")
.on({
    mouseover: function(e) {      
        $(this).css("background-color", "#fff")
    }
  , mouseleave:function(e) {
        $(this).css("background","transparent")
    }
})

jsfiddle http://jsfiddle.net/05q8zLsr/3/

 $(".overlay .map_link") .on({ mouseover: function(e) { $(this).css("background-color", "#fff") } , mouseleave:function(e) { $(this).css("background","transparent") } }) 

 .map_image { display: block; width: 200px; height: 596px; position: relative; border: 1px solid gray; } .map_image .map_link { display: block; position: absolute; text-indent: -999em; overflow: hidden; border: 2px solid orange; } .map_image #map_link_0 { top: 106px; left: 20px; } .map_image #map_link_1 { top: 106px; left: 79px; } .map_image #map_link_2 { top: 106px; left: 138px; } .map_image #map_link_3 { top: 160px; left: 20px; } .map_image #map_link_4 { top: 160px; left: 79px; } .map_image #map_link_5 { top: 160px; left: 138px; } .map_image #map_link_6 { width: 30px; height: 27px; top: 0px; right: 0px; } .map_image #map_link_7 { width: 196px; height: 27px; top: 33px; left: 0px; } .map_image #map_link_8 { bottom: 2px; left: 6px; } .map_image #map_link_9 { bottom: 2px; left: 43px; } .map_image #map_link_10 { bottom: 2px; left: 80px; } .map_image #map_link_11 { bottom: 2px; left: 117px; } .map_image #map_link_12 { bottom: 2px; left: 155px; } #map_link_8, #map_link_9, #map_link_10, #map_link_11, #map_link_12 { height: 30px; width: 30px;} #map_link_0, #map_link_1, #map_link_2, #map_link_3, #map_link_4, #map_link_5 { width: 37px; height: 37px; border-radius: 5px; } .overlay { background:rgba(0,0,0,.45); width: 200px; height: 596px; opacity:0; -webkit-transition: opacity .25s ease; -moz-transition: opacity .25s ease;} .map_image:hover .overlay { opacity:1; }
