无法在JS灯箱中更改布局
更新：https://jsfiddle.net/ymLd152e/
它没有100％干净地工作（不得不修改一些东西），但我认为它足以示范。
我找到了一个免费的javascript灯箱，并将其集成到我的网页中。打开图像时看起来像这样：
现在，我试图将图片计数器和图像下方的X移动到捕获所在的同一行。但我在JS方面还不够好。
Lighbox的HTML布局由JS＆amp; amp; JQuery的。我找到了变量，但是当我将值从 appendTo（包装器）更改为 appendTo（图像）时，元素就会消失 - 在浏览器和显示的HTML中检查员（FireBug）。
有谁能帮我弄清楚我在这里失踪了什么？正如我所说的那样，我现在已经研究了这个剧本几天了，并且理解了很多东西，但解决方案仍然让我不知所措。
这是脚本（对不起，如果它有点长 - 我只需要朝着正确的方向轻推）：

答案 0 :(得分：0)
您可以通过更改CSS来完成此操作。
将top: 30px和bottom:30px
.sl-wrapper .sl-close更改为.sl-wrapper .sl-counter
此更改告诉元素从底部测量30px，而不是从顶部向下测量30px。您可能希望调整这些数字以适应，并且您会注意到您可能还想调整left和right值。
因此，新的CSS更改如下所示：
/* line 54, ../sass/simplelightbox.scss */
.sl-wrapper .sl-close {
display: none;
position: fixed;
right: 30px;
bottom: 30px;
z-index: 1015;
margin-top: -14px;
margin-right: -14px;
height: 44px;
width: 44px;
line-height: 44px;
font-family: Arial, Baskerville, monospace;
color: rgb(218,218,218);
font-size: 2.6rem;
}
/* line 70, ../sass/simplelightbox.scss */
.sl-wrapper .sl-counter {
display: none;
position: fixed;
bottom: 30px;
left: 30px;
z-index: 1015;
color: rgb(222,222,222);
font-size: 0.9rem;
}
