Beamer：在标题内的 beamercolorbox 中垂直对齐子部分

tag-icon • tag-icon beamer header-footer vertical-alignment
Beamer：在标题内的 beamercolorbox 中垂直对齐子部分

我想自定义我的 beamer 演示文稿。不幸的是，我的标题有问题。我更改了字体（这里我使用了标准字体，所以你可以试试），这导致部分标题内容被框架标题遮挡（使用新字体排版的内容空间不够）。所以，我决定让标题对提供的内容更具响应性。我让它的高度取决于部分的数量和用于排版部分标题的字体（我知道代码不是很好，但我不太了解 TeX/LaTeX）。

如果我的节和子节数量相等，那么一切都会正常。如果子节比节少，我希望子节居中或与框顶部对齐。不幸的是，它们与框底部对齐，这看起来很奇怪（见屏幕截图）。您有什么想法可以解决此问题吗？ 最佳情况

下面我提供了 MWE，如果需要，请随意完全重写它。

预先感谢您的任何帮助。

任何字体变化（使用更高/更粗的字体、更大的尺寸或默认字体的基线 => 尝试不同的注释替代方案）都会产生遮挡效果，因为标题没有响应。下面是一些例子。

自提交以来https://github.com/josephwright/beamer/commit/5e32665a0382d91e3ebddc5080c717f962a8e0fasection in head/foot（应包含在 beamer 3.71 或更新版本中），beamer在创建标题时会自动考虑字体的字体大小。

因此，无需任何人工干预，您的示例
