Theme Builder Gradient Colors

Yes, you can use gradient backgrounds anywhere with Wisej themes. See image below. The styles are gradientStart, gradientEnd, or colorStart, colorEnd, colorStartPosition, colorEndPosition, orientation: https://wisej.com/docs/html/Styles.htm

However, the gradient color is treated in css as a background image and we we used background images for table row headers to indicate the current row and other states and the theme sets the size to 16 x 16. The same for the column headers, we use the background image to set a custom image on the headers. You you’d have to remove the background size when using gradients on the column headers.

A mixin for the column header could be like this (of course you’d have to also change the “hovered” and maybe other states):

{
 "appearances": {
   "table-header-cell": {
     "inherit": "table-header-cell",
       "states": {
         "default": {
           "styles": {
              "backgroundSize": null,
              "startColor": "red",
              "endColor": "green"
            }
          }
      }
    }
  }
}
