Customize the color of the horizontal line in React using dynamic properties

Is there a way to customize the color of an <hr /> element in a React application? If we were to use a functional component to accomplish this, how would we go about it?

Answer №1

There's really nothing too fancy about it.

const Line = ({ color }) => (
  <hr
    style={{
      borderColor: color,
    }}
  />
);

const Component = () => (
  <div>
    This is a red line. <Line color="red" />
    This is a green line. <Line color="green" />
  </div>
);

ReactDOM.render(<Component />, document.querySelector("main"));
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/16.6.3/umd/react.production.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react-dom/16.6.3/umd/react-dom.production.min.js"></script>
<main/>

Answer №2

In my personal experience, when it comes to styling the <hr> element without going too far from its default appearance, I find that using the CSS property border-color works best. Here is an example of how you can style it:

.foo { border-color: black; }
<hr class="foo" />

When working with React, you can start by using their basic CSS prop and then customize it further based on your needs.

render() {
  let className = 'hr-color';
  if (this.props.isActive) {
    className += ' foo';
  }
  return <hr className={className}/>
}

Answer №3

To achieve the desired effect, apply the following CSS:

    hr {
        background-color: blue; //or any color of your choice.
        height: 2px;
    }
