React Js Change Font Size | inline Style | Increase | Descrese

React Js Change Font Size Dynamically:In Reactjs, you can dynamically change the font size by utilizing the useState hook to manage the font size state. Create a state variable to store the font size value and use inline styles with JSX to apply the font size to the desired element. Implement an event handler to update the font size based on user input or any other trigger. When the state updates, React will automatically re-render the component with the new font size, providing a seamless and dynamic font size adjustment in the application

How do you change font size conditionally using inline styles and a ternary operator in Reactjs?

In this React.js code, a functional component named "App" is created. It uses the "useState" hook to manage the state of "isLarge," which determines the font size. When the "Toggle Font Size" button is clicked, it toggles the "isLarge" state between true and false. The font size of the paragraph is set using inline styles with a ternary operator. If "isLarge" is true, the font size is '24px,' and if it's false, it's '16px.' This allows for dynamic font size changes based on the state. The rendered result displays a button to toggle the font size of the text in the paragraph.

How can I dynamically change the font size in Reactjs

This Reactjs code creates an App component that allows users to dynamically change the font size of a text element. It uses the useState hook to maintain the fontSize state, initially set to 16. The handleFontSizeChange function is responsible for updating the state based on the input value provided by the user. The rendered component displays the text with the dynamically adjusted font size, along with an input field that lets users enter a font size value between 10 and 50. As users change the input value, the text's font size updates accordingly in real-time.

React Js Change Font Size Dynamically Example

<script type="text/babel">
      const { useState } = React;

      // Define the App component
      const App = () => {
        const [fontSize, setFontSize] = useState(16);

        // Function to handle font size changes
        const handleFontSizeChange = (event) => {
          const newSize = parseInt(event.target.value, 10); // Parse the input value as an integer
          setFontSize(newSize);
        };

        return (
          <div className="container">
            <h3>React Js Change font size dynamically</h3>
            <div className="dynamic-font" style={{ fontSize: `${fontSize}px` }}>
              Text with dynamic font size
            </div>
            <input
              className="font-size-input"
              type="number"
              value={fontSize}
              onChange={handleFontSizeChange}
              min="10" // Set the minimum value allowed
              max="50" // Set the maximum value allowed
            />
          </div>
        );
      };

      ReactDOM.render(<App />, document.getElementById("app"));
