我喜欢将导航放在容器外面并定位在v和h中心（参见图片以供参考）

此外，移动标题也是我正在努力的事情。

Answer 1

将导航移动到滑块之外非常简单，您只想通过css调整定位。

ul.bjqs-controls.v-centered li.bjqs-prev a {
  left: -49px;
}
ul.bjqs-controls.v-centered li.bjqs-next a {
  right: -51px;
}

只需添加这些值，即可将nav置于元素之外。就标题而言，它绝对位于该元素内部，因此您需要查看p.bjqs-caption以查看如何更改CSS以允许将其放置在滑块之外。编写脚本的方式可能无法实现。

在我第一次尝试时，它会在滑块下消失，可能是因为它上面有overflow: hidden。
