Navbar

Steps

Data

Check the data.jsx file and find two arrays: one for links and one for social icons. Notice how icons from react-icons can be used directly in the data structures. Just make sure in Vite to use .jsx file extension

Initial Approach

Set up a Navbar component with a showLinks state value (boolean). Import the links from data and render them conditionally in the Navbar based on the showLinks state value. Set up a button that toggles the value and as a result, toggles the links. Set up CSS for the Navbar.

Fixed Approach

Hide links by default in the CSS. Create a class that displays links with a fixed height. Refactor the JSX in the Navbar to toggle the class, which in turn toggles the Navbar.

Dynamic Approach

Use the useRef and getBoundingClientRect() function, to get exact height of links

Javascript Nuggets - Width/Height

Complete App

Finally, add social links and CSS to render the Navbar on the big screen.

Application Flow

The flow of the application should look something like this:

• Check the data.js file and find two arrays: one for links and one for social icons.

• Set up a Navbar component with a showLinks state value (boolean). Import the links from data and render them conditionally in the Navbar based on the showLinks state value. Set up a button that toggles the value and as a result, toggles the links. Set up CSS for the Navbar.

• Hide links by default in the CSS. Create a class that displays links with a fixed height. Refactor the JSX in the Navbar to toggle the class, which in turn toggles the Navbar.

• Use the useRef and getBoundingClientRect() function, to get exact height of links

• Add social links and CSS to render the Navbar on the big screen.

          <button className='nav-toggle' onClick={toggleLinks}>
            <FaBars />
          </button>
        </div>
        {showLinks && (
          <div className='links-container'>
