The Gutenberg editor introduced in WordPress 5.0 made it much easier to add elements to your posts. Whether you want to embed a YouTube video, a form, a table, or one of many other types of content, there is probably a block that you can add to do so easily.
But occasionally you may actually need to add some HTML code to one of your posts, and you might find that it’s difficult to do what you are trying to accomplish. Fortunately there is a Code Editor in Gutenberg that you can enable which allows you to type HTML directly into your post.
