编辑引导幻灯片

Question

我想让我的引导幻灯片看起来像这样：

有谁知道我如何做到这一点？所以我想要边缘的导航，带有背景颜色的白色图标和居中的文本。如果可能的话，有人可以告诉我如何编辑引导较少的源来做到这一点。

Answer 1

好的，我找到了答案。只需将引导源 carousel.less 文件编辑为：

carousel.less

    //
// Carousel
// --------------------------------------------------


// Wrapper for the slide container and indicators
.carousel {
position: relative;
}

.carousel-inner {
position: relative;
overflow: hidden;
width: 100%;
margin-bottom: 50px;

> .item {
display: none;
position: relative;
.transition(.6s ease-in-out left);

// Account for jankitude on images
> img,
> a > img {
  &:extend(.img-responsive);
  line-height: 1;
}

// WebKit CSS3 transforms for supported devices
@media all and (transform-3d), (-webkit-transform-3d) {
  .transition-transform(~'0.6s ease-in-out');
  .backface-visibility(~'hidden');
  .perspective(1000px);

  &.next,
  &.active.right {
    .translate3d(100%, 0, 0);
    left: 0;
  }
  &.prev,
  &.active.left {
    .translate3d(-100%, 0, 0);
    left: 0;
  }
  &.next.left,
  &.prev.right,
  &.active {
    .translate3d(0, 0, 0);
    left: 0;
  }
}
}

> .active,
> .next,
> .prev {
display: block;

}

> .active {
left: 0;
}

> .next,
> .prev {
position: absolute;
top: 0;
width: 100%;
}

> .next {
left: 100%;
}
> .prev {
left: -100%;
}
> .next.left,
> .prev.right {
left: 0;
}

> .active.left {
left: -100%;
}
> .active.right {
left: 100%;
}

}

并在 variables.less 中设置您的主题颜色。使用 Koala 之类的程序重新编译为 bootstrap.css。 http://koala-app.com/

Answer 2

您应该使用 Bootstrap 轮播。参考下面的链接 https://www.w3schools.com/bootstrap/bootstrap_carousel.asp
