Is it possible to create a full width row in WordPress’s editor window? [closed]

One way of doing that is to do a little bit of clever CSS hacking 😉

Here’s the solution by Sven Wolfermann (codepen)

.full-width {
  width: 100vw;
  position: relative;
  left: 50%;
  right: 50%;
  margin-left: -50vw;
  margin-right: -50vw;
}

error code: 523
