Mobile Nav example in React

Demo hosting URL

https://rv-mobile-nav-example.web.app

Minor subjects covered

• Multiple media queries and gutters with consistent positioning.
• Using components for storing Navigation and Socials which don’t have their own stylesheets
• Position fixed header, mobile navigation menu and hamburger icon
• Styling the a, a:link and a:visited elements
• Transition rule (rule, length, timing-function) eg: (all, 300ms, linear)
• Using javascript to conditionally display html classes, and control css
• Prevent body scrolling with body { overflow: hidden;}
• Layer the main, header, aside and button.hamburger with z-index rules
• Use the ‘document’ keyword to grab the document
• Use the .querySelector() function which is always available on the document element to return an Element
• Use the .addEventListener() function which is always available on Elements to listen for ‘click’ events and run a function
• Rewrite our javascript solution in the React way (where we use the useEffect hook to run our function whenever ‘menuOpen’ changes, and tidy up when we’re done.)
• hide mobile menu on resize events
• add another useEffect hook to close the mobileMenu when a navigation event happens
• animate the hamburger icon into a cross when the mobile menu is open

Available Scripts

In the project directory, you can run:

npm start

Runs the app in the development mode.
Open http://localhost:3000 to view it in your browser.

The page will reload when you make changes.
You may also see any lint errors in the console.

npm test

Launches the test runner in the interactive watch mode.
See the section about running tests for more information.

npm run build

Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.
Your app is ready to be deployed!

See the section about deployment for more information.

npm run eject

Note: this is a one-way operation. Once you eject, you can't go back!

If you aren't satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.

Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you're on your own.

You don't have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn't feel obligated to use this feature. However we understand that this tool wouldn't be useful if you couldn't customize it when you are ready for it.
