Why is the transition: background red in syntax highlighting (Visual Studio)?-CodePudding

I am a teacher and had a student ask why the "background" is red in color. This is in Visual Studio Code using the Dark theme. I have tried looking in the settings for syntax highlighting to identify different colors, but haven't had any luck. Same with browsing the web for this theme's color usage.

CodePudding user response：

background is not an animatable property. More on this

Override default style

In case you're looking to change the default foreground (color) or the default fontStyle of this scope, you can go to vscode command prompt and select Open settings (JSON) then add the following :

"editor.tokenColorCustomizations": {
  "[Default Dark ]": {
    "textMateRules": [
      {
        "scope": ["invalid.deprecated.color.system.css"],
        "settings": {
            "foreground": "#F44747",
            "fontStyle": "italic strikethrough"
        }
      },
    ]
  },
}

Result:
