simpleslides 的设计目标是让创建新样式变得简单。因此，现有样式的设计并未考虑定制。因此，调整现有样式与创建新样式的工作量大致相同（只要您了解基本的 ConTeXt 环境，创建新样式就不难）。

beforeauthor为了获得您想要的设计，我会更改...afterauthor和beforedate...的参数afterdate，并调整默认的 MP 背景。

\usemodule[simpleslides]
          [
            style=Rounded,
            color=red,
            font=Helvetica,
          ]


\defineframedtext
  [authorframe]
  [
    width=0.85\textwidth,
    frame=off,
    overlay=none,
    before=,
    after=,
  ]

\definenarrower
    [datenarrower]
    [
      before={\blank[2cm]},
      left={9cm},
      default=left,
    ]

\setupTitle
  [
    before={\blank[force,0.2cm]},
    authorstyle={\switchtobodyfont[12pt]},
    authorcolor=black,
    beforeauthor=\startauthorframe,
    afterauthor=\stopauthorframe,
    beforedate={\startdatenarrower},
    afterdate={\stopdatenarrower},
  ]
