Styled Components are a tool

Focus on the ideas in this presentation.

Alternatives: emotion, DIY

Main Ideas

1. When are styled components the right tool?
2. Use props to update UI instead of classes
3. Harness the power of ThemeProvider

Bonus: Clarified div soup. Clearer templates.

What makes a good styled component?

• Components whose business domain is the UI

Anything w/ complex UI!

• A presentational/dumb component

Benefits of styled components

• Styles travel with the component

• You update the UI based on props, not adding/removing classes

• Random class names by default. (No class name/namespacing issues.)

• Theming support is built in

Theming Support?

• Theme is magically available in all styled components

• ThemeProvider uses provide/inject to give you a Theme object

• You can override the theme

• Styled components come with a ThemeProvider component.

Me, adding custom colors via :style

Let's look at code

• A Simple Button

• A Card with Something Extra

• Refactor to add theming

Considerations w/ Dynamic Theming

• styled-components/polished

• Use readableColor on dynamic backgrounds

• Use lighten/darken with a base color.
  • Button hover state, active state
  • Stylistic touches based off the theme color

you have to do in JS​
