我想用纽卡斯尔大学的 LaTeX 投影仪模板制作一个演示文稿投影仪https://github.com/nitrogl/nclbeamer（Overleaf 中的类似模板
https://www.overleaf.com/latex/templates/university-of-york-un-official-beamer-template/gsmdqbkqkssm）。但是当我尝试创建一个定理（或定义、引理、推论……）时，它显示如图所示。我不知道为什么显示那一行，以及为什么文本从行尾开始。我想自定义这些环境，以便“定理”看起来像“alertblock”，
“定义”看起来像“exampleblock”，“引理”看起来像“blueblock”

您的主题有一个相当值得怀疑的想法，即重新定义环境block，这是投影仪中的核心元素，例如用于创建定理等。
您可以恢复到定理开始时的原始定义（根据需要更改颜色）：
