Themes

Custom themes for PowerShell Universal apps.

Built-In Themes

You can use built-in themes by using the Get-UDTheme cmdlet. If you run the cmdlet without parameters, it will return a list of all available themes.

$Theme = Get-UDTheme -Name 'MaterialDesign'
New-UDApp -Theme $Theme -Title 'Hello' -Content {
    New-UDButton -Text "Test " -OnClick {
        Show-UDToast -Message 'HEllo'
    }
}

Setting the default theme

You can set the default theme to either Light or Dark using the -DefaultTheme parameter.

New-UDApp -Title 'Hello' -Content {
    New-UDButton -Text "Test " -OnClick {
        Show-UDToast -Message 'HEllo'
    }
} -DefaultTheme dark

Custom Themes

PowerShell Univeral apps are built on MUI. MUI provides a built-in theme system that apps take advantage of. You can utilize this theme system by providing a hashtable of options to the New-UDApp 's -Theme parameter.

Here's an example of changing the theme's main color.

$Theme = @{
    palette = @{
        primary = @{
            main = '#111111'
        }
    }
}
New-UDApp -Theme $Theme -Title 'Hello' -Content {
    New-UDButton -Text "Test " -OnClick {
        Show-UDToast -Message 'HEllo'
    }
}

Note that when specifying keys that require a number, ensure that the key is specified as a string.

grey = @{
    '50'              = '#fafafa'
    '100'             = '#f5f5f5'
    '200'             = '#eeeeee'
    '300'             = '#e0e0e0'
    '400'             = '#bdbdbd'
    '500'             = '#9e9e9e'
    '600'             = '#757575'
    '700'             = '#616161'
    '800'             = '#424242'
    '900'             = '#212121'
    A100              = '#d5d5d5'
    A200              = '#aaaaaa'
    A400              = '#303030'
    A700              = '#616161'
    contrastThreshold = '3'
    getContrastText   = 'f E()'
    augmentColor      = 'f B()'
    tonalOffset       = '0.2'
}

Changing the background color

You can change the page background color by setting the background default color. To adjust the header background color, set the primary main color.

$Theme = @{
    palette = @{
        primary = @{
            main = '#876a38'
        }
        background = @{
            default = '#876a38'
        }
    }
}
New-UDApp -Theme $Theme -Title 'Hello' -Content {
    New-UDButton -Text 'Hello' 
}

Supporting dark and light palettes

To support dark and light palettes, you can define a dark and light sections in your hashtable. They have the same properties as a theme.

$Theme = @{
    light = @{
        palette = @{
            primary = @{
                main = "#fff"
            }
        }
    }
    dark = @{
        palette = @{
            primary = @{
                main = "#333"
            }
        }
    }
}
New-UDApp -Theme $Theme -Title 'Hello' -Content {
    New-UDButton -Text 'Hello' 
}

Changing the font size

To change the font size, set the typography fontSize property.

$Theme = @{
    typography = @{
        fontSize = 20
    }
}
New-UDApp -Theme $Theme -Title 'Hello' -Content {
    New-UDButton -Text 'Hello' 
}

Changing default button colors

$Theme = @{
    palette = @{
        grey = @{
            '300' = '#000'
        }
    }
}
New-UDApp -Theme $Theme -Title 'Hello' -Content {
    New-UDButton -Text 'Small Button'
}

For a full list of options available for the theme system, you can look at the default theme for MUI.

Component Overrides

You can override any component CSS value using the theme engine. In order to override a component's base theming, you will need to identify the CSS class name applied to that element.

To identify a component's CSS classes, use the developer tools of your browser. Right click on the component you wish to style and click Inspect Element.

This will highlight the HTML elements that make up that component. In the image below, you will see we have numerous CSS classes being applied such as:

• MuiButtonBase-root

• MuiButton-root

• MuiButton-label

• MuiTouchRipple-root

In order to override these various elements, you will need to add an overrides key to your theme.

$Theme = @{
   overrides = @{
   
   }
}

Next, you'll need to add keys to the overrides for each element you wish to modify. Notice that I have not included the portion of the class name after the hyphen.

$Theme = @{
   overrides = @{
       MuiButton = @{
       
       }
   }
}

Now, add the subitems you wish to modify to the class name.

$Theme = @{
   overrides = @{
       MuiButton = @{
           root = @{
           
           }
           label = @{
           
           }
       }
   }
}

The last step is to define the CSS properties you wish to apply to elements that use these classes.

$Theme = @{
   overrides = @{
       MuiButton = @{
           root = @{
               padding = 20
           }
           label = @{
               fontSize = 40
           }
       }
   }
}

For more examples, look at the Onepirate and Paperbase themes below that include many component overrides.
