How to set color hints in WebStorm

---

When I was using WebStorm to learn the front-end, I was asked on 2016-02-01 how to set the color prompt of WebStorm. It is said that there is no setting method for Du Niang. I searched for the settings and found the location. Today I wrote this setting method to explain.

Software version number: JetBrains WebStorm 8.0.4

Opening steps

1 File-Settings

2 IDE Settings-Editor

3 Appearance-Show CSS color preview icon in gutter & Show CSS color preview as background

Actual effect

The enlarged part and the part circled by the yellow rectangle are the effects of Show CSS color preview icon in gutter: use a small colored square next to the line number to identify the selection s color.

The part circled by the red rectangle is the effect of Show CSS color preview as background: the background color of the color value is the selected color.
