Hi,

We use CSS zebra striping with a custom WebHelp Publishing Template, initially created for Oxygen 26.1. With Oxygen 28.1 this does not work any longer. A look under the hood reveals that the following CSS from topic.css is the culprit:

Code: Select all

.simpletable>:not(caption)>*>*,
.table>:not(caption)>*>* {
    background-color: var(--wh-primary-bg,#fff);
    color: var(--wh-primary-color,#000)
}

I think this rule is a bit too broad and should be more precise in targeting the HTML elements to which it should be applied.

Best regards,
Frank

Hi Frank,

These new default rules are coming from newer Bootstrap versions, you can easily override it by targeting the cell instead of the row:

Code: Select all

tr:nth-child(even) > td {
  background-color: #f2f2f2;
}

Regards,
Julien

Hi Julien,

Thanks for the background information and the pointer. I just reset the rule by putting the following code before my customization, because it also affected the styling of the table header:

Code: Select all

.simpletable>:not(caption)>*>*,
.table>:not(caption)>*>* {
    background-color: inherit;
    color: inherit;
}

Best regards,
Frank
