CSS Grid Overlay Chrome 插件, crx 扩展下载

                    
Easily check the grid alignment of your page across breakpoints.
Supports multiples breakpoints and the usual grid values (gutters, columns, max width, etc).

Configurations can easily be saved and shared among team members as json objects.

Example conf: 

[
  {
    "columns": 4,
    "margins": 16, // px before and after the first and last column
    // these gutters work like margins: 
    // if distance between columns is 32px, gutters are 16
    "gutters": 16, 
    "from": 0, // start of breakpoint in px
    // Optional values
    // "to": 599, end of breakpoint in px
    // grid will be centered after this maxWidth in px
    // otherwise it'll be full width
    // "maxWidth": 1440, 
    // if you want to move the grid 
    // (e.g. in a style guide with a left sidebar
    // you'd use offsetLeft to push the grid to the right
    // "offsetTop": 0,
    // "offsetRight": 0,
    // "offsetBottom": 0,
    // "offsetLeft": 0,
    // "backgroundColors": {
    //   "columns": "rgba(234, 23, 140, .3)",
    //   "gutters": "rgba(0, 231, 255, .3)",
    //   "margins": "rgba(0, 191, 165, .3)"
    // }
  }
