html - Chrome 尝试将简单的 html 文档打印为 31K+ 空白页面

问题描述

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：

Chrome在打印模式下将一个简单的页面评估为数万页

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

有任何想法吗？

                  <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>

解决方案

正如@kaiido 所指出的，罪魁祸首似乎是.block-row该gap物业的空置。

我们遇到了同样的问题，并在 Chrome 中发布了一个错误，请参见链接。

gap我们的解决方案是在容器为空时移除该属性。

在你的情况下

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