css - 在 CSS 灯箱中放大图像

Question

作为CSS的新手，我还处于学习阶段，所以请多多包涵。我有一个完全用 CSS 构建的灯箱，我想生成比当前显示的更大的图像(灯箱内的图像，而不是主页上的缩略图)，但想不出任何方法来实现这一点!

HTML:

<ul class="gallery">
<li>
    <a href="#img1"><img src="thumb-01.jpg" alt="Image 1 Thumb"></a>
    <article id="img1">
        <figure>
            <a href="#img2"><img src="img01.jpg" alt="Image 1"></a>
        </figure>
        <nav>
            <a class="close" href="#close">Close</a>
            <a class="arrow prev" href="#img25">Previous</a>
    <a class="arrow next" href="#img2">Next</a>
        </nav>
    </article>
</li>

我快速构建了一个 Codepen为你。我简单地插入了一些占位符图像，无论我使用什么尺寸的图像，它都不受你的 CSS 限制。我的建议？只需上传更大的图像。要摆弄我的设置，请像这样配置 placehold.it 图像:

<img src="http://placehold.it/200x200">

200x200 可以是您喜欢的任何尺寸。

编辑更新如下:

起初，我以为您想增加灯箱图片的尺寸。但现在我认为您可能在谈论图库中图像的大小，这些图像在您的 CSS 中受到以下声明的限制:

.gallery li > a img{
    max-width: 100%;
}

因此，您图库中的图片将无法增长到超过其父级宽度的 100%。
