Chrome 尝试将简单的 html 文档打印为 31K+ 空白页面

Question

我有一个简单的 html 文档（参见 - https://5fa3b1d135e99.htmlsave.net）。当我尝试打印（cmd/ctrl+P）此文档时，chrome 将打印大小评估为 31,776 页：

经过一些研究，当从.block-row 中删除gap 属性时，它是固定的，但我不知道是什么原因，另外 - 我确实需要这个间隙。

有什么想法吗？

                  <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>

Answer 1

正如@kaiido 指出的那样，罪魁祸首似乎是带有gap 属性的空.block-row。

我们遇到了同样的问题并在 Chrome 中发布了一个错误，请参阅link。

我们的解决方案是在容器为空时删除gap 属性。

你的情况

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