Where i can debug

is there any way to add background clour to only one category

To access the DevTools, open a web page or web app in Google Chrome. Either:

Select the Chrome menu Chrome Menu at the top-right of your browser window, then select Tools > Developer Tools.
Right-click on any page element and select Inspect Element.
The DevTools window will open at the bottom of your Chrome browser.

There are several useful shortcuts for opening the DevTools:

• Use Ctrl+Shift+I (or Cmd+Opt+I on Mac) to open the DevTools.
• Use Ctrl+Shift+J (or Cmd+Opt+J on Mac) to open the DevTools and bring focus to the Console.
• Use Ctrl+Shift+C (or Cmd+Shift+C on Mac) to open the DevTools in Inspect Element mode, or toggle Inspect Element mode if the DevTools are already open.

To change the color or background for each categories you can use the following code:

.category-economy .container {
    background: #fff;
}
.category-economy {
    background: #000;
}

Also, very simple to change background for another categories. Just need change the category name in the code.
Example: Governance categories.

.category-governance {
    background: #000;
}
.category-governance .container {
    background: #fff;
}

If you want to add color to widget in each categories, please tell me know the widget name that you want to change.
Hope this helps !

Please how i can chng the background colour ofa single widget – dw focus – 1.1.0

You can tell me detail about the widget name and page, categories or single page that you want to change the background color for widget.
If you want to change background color of widget in each categories page, you can use categories class name + widget class name. To find the class name you can use debug.
Hope you understand what I mean.
