ReSharper highlights selectors, properties and values of properties, at-rules (such as
@media), functions that can be used as property values, pseudo-classes, and so on. Default syntax highlighting for CSS: In addition to standard syntax highlighting that is common for all file types supported by ReSharper, it provides some special features for CSS files. Any color value is underlined with a respective color, it doesn't matter how it is defined (color name, hex code or RGB code). When you hover the mouse pointer over the color value, a tooltip appears.
