  Hi,

  Regarding the two areas you mentioned, we have checked the SpreadJS styles and identified the CSS classes responsible for these UI elements:

  Arrow icon / top-left corner triangle

  .gc-corner-triangle-normal
  .gc-corner-triangle-hover
  .gc-corner-triangle-selected

  Intersection of the vertical and horizontal scrollbars

  .gc-footer-corner

  You can override these classes in your application CSS to customize their appearance for dark mode.
  
  For example:

  .gc-corner-triangle-normal {
    /* Customize the normal state */
  }
  
  .gc-corner-triangle-hover {
    /* Customize the hover state */
  }
  
  .gc-corner-triangle-selected {
    /* Customize the selected state */
  }
  
  .gc-footer-corner {
    /* Customize the scrollbar intersection */
  }

  Best regards,
  
  Priyam
