Bootstrap 模态全屏图像

Question

我为我的画廊创建了一堆图像。我正在努力实现几件事。

1) 模态框上的透明背景。

2) 中心图片

3) 720px 960px 最大尺寸。保持对小型设备的响应

这是我的问题的一个活生生的例子。 https://www.zachnewberry.com/gallery-backup.html

这里是 CSS

/* Gallery Page */

.gallery {
    max-height: 150px;
    min-height: 150px;
    min-width: 100%;
}

.gallery-spacer {
    padding-top: 25px;  
}
#myModal{
    z-index: 9999;
}
.gallery-modal {
    max-height: 100%;
    min-width: 100%;
    align: center;
}
.modal-dialog {
    width: 100%;
    height: 100%;
    padding: 0;
    margin: 0;
}
.modal-content {
    min-height: 100%;
    height: auto;
    border-radius: 0;
}

Answer 1

要删除背景颜色，请将“背景：透明”添加到您的 .modal-content 类中。

.modal-content {
 min-height: 100%;
 height: auto;
 border-radius: 0;
 background: transparent;
}

要使图像居中，请使用自动边距：0，并为最大尺寸设置最大高度和最大宽度（假设您的意思是 720 像素宽度和 960 像素高度）

.carousel-inner > .item > img {
 margin: 0 auto;
 max-width: 720px;
 max-height: 960px;
}
