In addition to the editing techniques that are common for all file types, PyCharm provides specific
techniques for CSS, SASS, SCSS and LESS files.
In particular, it is possible to easily change color values without the necessity
to memorize and type color codes. The color properties are marked with the
icons of the corresponding color in the left gutter area of the editor. Use these icons to view colors and change
color values. When you point with your mouse cursor to the color icon, the pop-up window appears, showing the
color and its code.
