Leveraging CSS in React/JSX

I am struggling to understand how to implement CSS with React. I have tried using inline styles but couldn't get it to work. Additionally, I am unsure where to apply CSS in my JSX code within the react class.

For example, in one of my react classes, I have the following code:

render: function() {

    return (
        <div>
          <h1> Todos </h1>

          <form className="todoForm" onSubmit={this.handleSubmit}>
            <input
                type="text"
                placeholder="Enter task"
                value={this.state.text}
                onChange={this.handleChange}
                />
            <input
                type="submit"
                value="Submit todo"
                />
          </form>

          <h4> List of todos: </h4>

          <ToDoList deleteItem={this.deleteItem} listItems={this.state.submittedValues}/>
        </div>
    );

How can I style the input box in the form to have a green background or make the <h1> heading font blue? In CSS, I would simply link a CSS file to HTML and write: h1 { color: blue };. However, I am unsure how to achieve this in React.

Markup

<h1 style={styles.heading}>

Inline Styling Example

let styles = {
   heading: {
     fontColor: '#00f'
   };
}

Answer №2

Try using a class name for the input with type="text"

<input type='text' class='inputText' />

For your CSS .inputText { background-color: green; }

Remember to use class names as attributes for the component and to differentiate between class names and ids using a period (.) and pound (#) respectively.
