有人知道为什么会发生这种情况以及如何阻止它发生吗？

我目前正在设计一个仅供打印的 .css 文件的样式，而且我一生都不知道如何修复此行拆分。

这是问题的图片:

这是用 AngularJS 构建的，这个内容被拉入/被这个部分拉入:

            </div>
        </div>
    </div>

还有在 .subSection div 中打印的内容。

最佳答案

将其放入您的 CSS 中进行打印

@media print {
    div {
        break-inside: avoid;
    }
}

break-inside CSS 属性调整当前元素内的分页符。

注意: page-break-inside已弃用，但在某些情况下也可能是必需的。
