v1.12 and higher
Setting colors for underlining errors is now available initially through workbench.colorCustomizationsthe workspace settings. See here .
"workbench.colorCustomizations": {
"editorError.foreground": "#000000",
"editorError.border": "#ffffff"
}
Unfortunately, as far as I can find, currently my own settings are limited to this. For example, to highlight an error with a background color, you still have to resort to the plugin method below ...
v1.7.2 and higher
css vscode-custom-css.
custom-styles.css ( )
.monaco-editor.vs .redsquiggly,
.monaco-editor.vs-dark .redsquiggly {
background: rgba(255,255,255,0.2);
border-bottom: 1px solid #fff;
}
custom-styles.css, Preferences > User Settings (settings.json)
{
"vscode_custom_css.imports" : [
"file:///path/to/file/custom-styles.css"
]
}
(Mac: cmd + shift + P, Windows/Linux: ctrl + shift + P) Enable Custom CSS and JS, VS.
