缩放图像 onclick，但 bg-col 接管 img

Question

I am programming a website, where I have images of documents that I have to present to my clients. However, as the images are too small when viewed plainly from the website, I went to search for "onclick zoom" js/jq. I found this gem instead. But the problem now is that, I can view the zooming action, but image is unviewable after zooming.

Js (in html):

<script src="https://unpkg.com/zooming/build/zooming.min.js"></script>


<script>
        // Listen to images after DOM content is fully loaded
        document.addEventListener('DOMContentLoaded', function () {
            new Zooming({
                // options...
                bgColor: 'rgba(0,0,0,1)',
                customSize: '100%'
            }).listen('.img-zoomable')
        })
</script>

I used CDN and did as told in the documentation provided by the developers of this repo. However my images are still not fully "isolated" or zoomed. Here are some examples:

My code does what when hover:

My code does what when I click to "zoom" on image:

As you can see, after I clicked the image to zoom, I can view the zoom and translate part of the image, but then the whole screen turns black. I found out why this happened, cause of the bgColor: 'rgba(0,0,0,1)' in my zoom configuration. But that is supposed to be the background isn't it? I tried changing the opacity of it, to 0 , and it technically worked, with the background still visible. I also read the part in their github page that

Caveats / Limitations

Avoid working with fixed position images #34. Image won't be visible after zoom-in if any parent element has style overflow: hidden #22 .

I tried the alternative of removing the existing overflow: ___ scss from all parent, but the image turned out to be still hidden behind the background somehow. Does anyone know what I am doing wrong, and how could I resolve this issue?

Answer 1

I think the css is a bit messy. When you look into the dev tools you can see a lot of them are not being taken into consideration and some of the css is unnecessary. I cleaned up a bit and I can see the image being zoomed in:

I don't know how much is this of a help but I am pretty sure once you clean up the code (maybe start from scratch) you will be able to see the images working as expected.
