Hello 
Is there a way to override default css for all widgets ?
For example, I would like all background-color of all webix widgets to become red.
Found this (Webix Skin Builder), but I would like to override dark skin, which is not available here 
Thanks !
Hmm… I also waiting for this

Hello Jean_Louis
To override default css the main changes need to be made via css:
.webix_view {
background-color: #d31919;
}
For more info on the CSS classes you need to override (at least in regards to specific widgets), you can reference the CSS image maps in our docs - CSS Image Maps of Styling and Animation, Styling of Widgets Webix Docs.
As for customizing skins for some components ( such as charts, forminput messages ) you can redefine the color variables where the color is written directly into their styles in the source code.
Please take a look at the example: Code Snippet
Also I want to assure you that we are aware of this request about skins and are considering it for our future updates.
Many thanks for your answer Natalia
