A step-by-step guide on implementing styled components in React.js with conditional statements

Embarking on my latest project with the goal of going "from Zero to Hero", I received a tip from a friend about styled components. Intrigued, I decided to ditch my traditional .css files and make the switch.

Although I understand the basics - using <MyComponent> followed by const MyComponent = styled.div with CSS properties in between - I'm facing some challenges.

I'm particularly struggling with these two scenarios:

  1. How do I convert 

    <div className={color ? 'header header-bg' : 'header'}>
    into styled components format? Can I use something like 
    <MyComponent={color ? 'header header-bg' : 'header'}>
    ? But then what's next?

  2. In regular stylesheets, I often group selectors like so:

    .class1, .class2, .class3 { styles }

Could someone guide me on how to achieve this with styled components? Currently, I find myself repeating similar code for each class (class1-3) which seems inefficient. I attempted creating variables like 

const Class1, Class2 = styled.div
but encountered issues.

Answer №1

Instead of using ternary operators, you can pass props in styled components. Check out this example for more information: Add background color conditionally in styled components and 

const Class1, Class2 = styled.div
won't work; you need to do it like this:

const Class1 = styled.div``
const Class2 = styled.div``
const Class3 = styled.div``
