删除标题/作​​者脚但保留页眉

Question

我在 overleaf 的 beamer 演示文稿中使用 Boadilla 主题，我想删除底部的标题、作者和日期框，同时保留我在图片中用黄色突出显示的页眉。还应删除正下方浅蓝色的矩形。

这是我的代码：

Answer 1

您可以使用\setbeamertemplate{footline}{}来重新定义脚线。

如果你不喜欢标题中的浅蓝色子部分栏，请不要将其设置为 true：\useoutertheme[subsection=false]{miniframes}

关于您的代码的其他一些评论：

• 您不应该使用带有当前 latex 版本utf8x的选项。请改用 -- 或者直接删除默认加载的选项inputencutf8inputencutf8

• 你不需要加载default主题，正如名称所示，它们是默认的

• 无需重新定义navigation symbols三次

• 无需使用\setbeamertemplate{caption}[numbered]两次

• 你不需要加载graphicx或hyperref在 beamer 文档中，beamer 会为你加载它们

• \date{\today}没有必要，这是默认显示的日期
