Web2 WebListbox - borderless and no alternating row color?

[Anthony_G_Cyphers]

Using what I provided above, replace the App.HTMLHeader content with this to combine everything and remove all borders and backgrounds:

<style>
  .borderlessTable,
  .borderlessTable table,
  .borderlessTable table td,
  .borderlessTable table th,
  .borderlessTable table tr,
  .borderlessTable .dataTables_scrollHead,
  .borderlessTable .dataTables_scrollBody {
    border-color: transparent !important;
    background-color: transparent !important;
    background-image: none !important;
  }
</style>

Comparison with a red rectangle behind both ListBoxes:
