Install this bookmarklet
Make a new bookmark in your browser (right-click on the bookmarks bar and click Add Page...)
- For the "Name" you might put "Validate HTML".
- Copy the code block below, paste this into the "Location" of a new bookmark.
javascript:void%20function(){javascript:(async%20function(){const%20a=document.querySelector(%22html%22).cloneNode(!0),b=document.createElement(%22div%22);b.appendChild(a);const%20c=`%3C!DOCTYPE%20html%3E${b.innerHTML}`.replace(/style%20type=\%22text\/css\%22/g,%22style%22),d=await%20fetch(`http://localhost:3000/nu/%23text-area`,{method:%22POST%22,cache:%22no-cache%22,mode:%22cors%22,headers:{%22Content-Type%22:%22text/html;%20charset=UTF-8%22,%22User-Agent%22:navigator.userAgent},referrerPolicy:%22no-referrer%22,body:c}),e=await%20d.text(),f=window.open(%22about:blank%22,%22%22,%22width=700,height=500%22);let%20g=e.replace(%22style.css%22,%22https://validator.w3.org/nu/style.css%22);g=g.replace(/\%3Cform(.*)form\%3E/g,%22%22),f.document.write(g)})()}();
When you click the bookmark while viewing a page in your web app, a window will be opened that will validate your HTML with W3C Validator (http://validator.w3.org).
We will use github repos throughout the course. If you are not familiar with git, or could use a refresher on how to use git, this is an excellent starter guide: https://guides.github.com/activities/hello-world/
- Make sure you have git installed: https://git-scm.com/downloads

This project was bootstrapped with Create React App.
In the project directory, you can run:
Installs the modules needed to run the app in node_modules.
Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.
The page will reload if you make edits.
You will also see any lint errors in the console.
Launches the test runner in the interactive watch mode.
See the section about running tests for more information.
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.
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.
You can learn more in the Create React App documentation.
