<span class="inline-block w-full h-full" />
<div class="absolute inset-0 overflow-hidden z-0 visible">
<div class="absolute inset-0 overflow-hidden z-0 visible">
<canvas id="pdf_canvas" ref="pdfViewer"></canvas>

Imagine that I have a white space in the background and I have a blue rectangle size 50px and I want it to move wherever the X and Y binding it. (Actually I want to drag it whet ever i want and bind it with X and Y too.)
You can use Tailwind's square bracked notation to generate a class on the fly with any arbitrary value:
<div class="top-[117px]">
<!-- ... -->
</div>
In your case, the resulting code would look something like the following:
<div :class="'top-[' + y + 'px] left-[' + x + 'px]'">
<!-- ... -->
</div>
