Gatsby: Set background image with CSS

 https://stackoverflow.com/questions/51776791/gatsby-set-background-image-with-css

Generally I keep component-specific images alongside their JSX and CSS files and general/global images in an images folder, so I might have a structure like this:

.
├── components
│   ├── button.jsx
│   ├── button.module.scss
│   └── button_icon.png
└── images
    └── logo.png

To reference button_icon.png from button.module.css I would do this:

background-image: url("./button_icon.png");

And to reference logo.png from button.module.css I would do this:

background-image: url("../images/logo.png");

Update: Lately I've been using Emotion with my Gatsby projects, which requires a slightly different approach. This would work with StyledComponents or Glamor as well:

import background from "images/background.png"
import { css } from "@emotion/core"

// Object styles:
<div css={{ backgroundImage: `url(${background})` }} />

// Tagged template literal styles:
const backgroundStyles = css`
  background-image: url(${background});
`
<div css={backgroundStyles} />
