Embedding tweets, extraordinarily simple.
Adding example HTML code, also really simple, great way to demo code without having to write all the annoying < and > html entities.
<!doctype html> <html lang="en"> <head> <title>Title of page</title> </head> <body> <p>some text in a paragraph</p> </body> </html>
Imagine if you wanted to enter your own HTML code, perhaps to embed something not already covered with Gutenberg’s blocks. You can do that too. Very convenient.
<div style="border:1px solid white; padding:5px;">My own html in a div. The code above generated this block</div>
The one thing I did not see at first was the lack of the “insert Read More tag”, but that is now a block by itself found under layout elements. Best of all, if you really miss the old editor, you can insert that as well. It can be found under formatting.
