What is Gutenberg? Gutenberg is a new editor for WordPress. Currently available as a plugin, WordPress has been developing this and plans to launch it as a core feature this August with version 5.0. Once you update your site to version 5.0, your site will use the new Gutenberg editor and the classic editor (the original one) will be available as a plugin if needed.
I recommend that before updating your site to 5.0, you set up a test/staging environment and install the Gutenberg plugin to see how your site handles it. You should also run a back up of your site. There are still many unknowns such as how various plugins will handle it, especially those with custom editors, metaboxes, Carbonfields, Advanced Custom Fields, etc. WordPress is still working out the kinks for their new editor as you can see on their GitHub page.
If you decide that you need more time before switching over to the new style editor, you can simply install the Classic Editor plugin now. Then go to settings > writing > Classic Editor Settings, you can select to replace the Gutenberg editor with the Classic Editor. It also allows you to use the Gutenberg editor by default and include optional links back to the Classic editor.
In order to give this new editor a test drive, I installed it on this site. I created my own feature image (the blue box above) and then snagged some iconic boxes from the WordPress Gutenberg page for the purpose of adding some floating images.
This demonstrates that WordPress is working hard to keep up with the latest trends and requests. To add these images, I was able to easily drag and drop from my desktop. I love this convenience and found that I can easily add alt tags if I look in the left column while adding the image. I didn’t need to go to the media library, a real time saver!
I’m curious to test this across various devices to see how it handles them. When we tested them earlier, we had difficulty with the images jumping around and not performing the way we expected them to. This is one example of the kinks that need to be worked out. However, they seem to have worked this out already.
Trust that your editor looks like your website” will be wonderful especially for non-coders. However, like I said, there may still be some kinks to work out. Again, I encourage you to visit the WordPress.org/Gutenberg page for more information on what the new editor will provide. I encourage you to make the switch sooner rather than later. If you have a simple site, you should be able to do so by simply backing up your site first and not bothering with the test/staging site. Make sure all of your plugins are updated also, since many of them are updating to accommodate Gutenberg.
