Since I've been doing a bit of HTML, I'm wondering, how hard is it to make a new block for scratch coding?I see a bit of every code on this website! (Html, javascript, CSS aka the pretty important codes for building websites) Another question: How do you make a website public? My coding book doesn't show how. Thanks for your time!-fuzzy

I'm not sure, but you would need to have a decent knowledge of javascript in order to create a block. If you know how to do a particular task in javascript, you should be able to create a block. You could check out ScratchX for user-created Scratch Modifications.
If you want to make a website public, you would need to secure a domain(eg- fuzzygamer512.com) which usually costs money. However, If you want to create a blog, you could try Google's Blogger or Wordpress.
Hope this helped!

You can see the code for the new Scratch website and editor at this page.
Note: They use a version of Javascript called NodeJS.

To get your website online, you need “website hosting”. This is where you upload your file to somebody else's server that is connected to the internet and they sort out all the complicated stuff like SSL and DNS.
There are a few file hosts, ranging from free to very expensive. The best cheap file host for beginners is probably GitHub pages.
1. Go to github.com and make an account - make sure you have your parents permission
Note:Your Username will be the start of your web address(username.github.io), so choose wisely.
2. Once you have an account, click the “+” button in the corner and click “New repository”
3. IMPORTANT: Call the repository username.github.io replacing “username” with your Github username.
4. Check “Initialize this repository with a README” and then create it.
5. Upload your website files into the repository. Note that your homepage should be called “index.html”
6. Wait about 30 mins for your website to launch then visit it at www.username.github.io

Hope I helped - any problems, tell me!

Should this be moved to the Advanced Topics forum? I'll report this to be moved in case.

Do you want to:
1) Build a block based coding langauge?
or
2) Add a block to Scratch.

If 1: With experience in JS with the canvas, you should be able to create something basic without too much trouble
If 2: Do you want to make a Scratch Extension or a Scratch Mod
Scratch Extensions are made in JS and are ran on scratchx.org
Scratch Mods are made in Actionscript from modifying the existing Scratch 2 source code.
