Chrome attempts to print a simple html document as 31K+ empty pages

I have a simple html document (see - https://5fa3b1d135e99.htmlsave.net). When I try to print (cmd/ctrl+P) this document, chrome evaluate the print size as 31,776 pages:

Chrome evaluate a simple page into tens of thousands of pages in print mode

After some research, when removing the gap property from .block-row, it's fixed, but I have no idea what's the cause, plus - I do need the gap.

Any ideas?

                  <div class="block-item">TypeScript supports JSX transpilation and code analysis. If you are unfamiliar with JSX here is an excerpt from the official website: JSX is an XML-like syntax extension to ECMAScript without any defined semantics. It's NOT intended
                      to be implemented by engines or browsers. It's NOT a proposal to incorporate JSX into the ECMAScript spec itself. It's intended to be used by various preprocessors (transpilers) to transform these tokens into standard ECMAScript.
                      The motivation behind JSX is to allow users to write HTML like views in JavaScript so that you can: Have the view Type Checked by the same code that is going to check your JavaScript Have the view be aware of the context it is
                      going to operate under (i.e. strengthen the controller-view connection in traditional MVC). Reuse JavaScript patterns for HTML maintenance e.g. Array.prototype.map, ?:, switch etc instead of creating new (and probably poorly typed)
                      alternatives. This decreases the chances of errors and increases the maintainability of your user interfaces. The main consumer of JSX at this point is ReactJS from facebook. This is the usage of JSX that we will discuss here.</div>

I didn't have any empty tags and was still getting this issue. So I just removed gap entirely when in print mode and that worked.

@media print {
    * {
        gap: 0 !important;
    }
}

As pointed out by @kaiido the culprit seems to be the empty .block-row with the gap property.

We encountered the same issue and posted a bug in Chrome see link.

Our solution was to remove the gap property when the container is empty.

In your case

.block-row { display: flex; gap: 32px; }
.block-row:empty { gap: unset; }
