Some big changes have come to the editing experience in WordPress. A new block-based editor is the first step toward an exciting new future with a streamlined editing experience site-wide.
- More flexibility with how content is displayed
- Insert any type of multimedia and have it embed automatically
- Each piece of content is in its own block and easily maneuverable with mouse or keyboard
- Tons of blocks available by default with more to come: paragraph, heading, preformatted text, quote, image, gallery, cover image, video, audio, columns with nested blocks, files, code, and more
Blocks are also reusable and many can easily be converted from one type to another. This new editing experience provides a more consistent treatment of design as well as content.
