Question

Has anyone customized Windchill 13 UI colors using xtheme-windchill.css

Hi everyone,

Has anyone successfully changed the background colors, navigation panel colors, or overall color theme in Windchill 13 by modifying xtheme-windchill.css?

I'm looking to:

  • Change the top banner/header color
  • Modify left navigation panel colors
  • Update background and accent colors across the UI

It is different compared to previous versions 12.1  and older

I did it at my last job, over a year ago, and it has changed from the method used in versions prior to 13.0. My notes just says that Windchill 13+ uses a color code for the banner background.

    Hi,

    I suggest following article CS453336 to register a custom CSS file, where you can override some of the colors defined in xtheme-windchill.css. You might want to start with the following:

    :root {
        --cds-color-gray1: #0000FF;
        --cds-color-gray2: #0000FF;
        --cds-color-gray10: #0000FF;
    }

    Best wishes,

    Giacomo
