WordPress Block Editor
Use the new WordPress block editor to create media-rich pages and posts and to control their layout without worrying about the alignment and organization of text, quotes, and images.
Move, edit, and customize each block, and the editor will display visual elements the way they’ll look on your live site. You can see a preview of the page by clicking on the Preview button before you hit “Publish”.
