there are some selector necessary, for example:

.split-editor {
  display: grid;
  grid-template-columns: repeat(2, 1fr);
  grid-template-rows: 1fr;
}

.split-editor:has(.milkdown-split-editor.hidden) {
  grid-template-columns: repeat(1, 1fr);
}

.milkdown-split-editor.hidden {
  display: none;
}

You can also add attributes to split edit view element if you want to build your own style logic or using atom css library like tailwindcss.

import { splitEditing } from '@milkdown-lab/plugin-fullscreen'
// ...
const editor = await Editor.make()
  .config(() => {
    ctx.set(splitEditingOptionsCtx.key, {
      wrapperAttributes: { class: 'grid grid-cols-2 grid-rows-none' },
      attributes: { class: 'bg-#eee' },
      hiddenAttribute: { class: 'hidden' },
      hiddenWrapperAttributes: { class: 'grid-cols-none' },
