An easy way for people who know CSS is to use the columns property. I’ve created some examples. See Multi column paragraph blocks

This was discussed in a number of slides but no conclusion was reached. In its present state Gutenberg is not as fully featured as other page builders. The eco system is not as fully developed for extra features. One problem I see with Elementor is that it’s not easy to migrate from using Elementor to not using Elementor. Ditto for other page builders. I understand some work has been done on integrating Elementor into Gutenberg.

A number of the attendees who use ACF a lot are happy to discuss the subject. I purchased ACF Pro a while ago, but have done very little with it. There’s also an ACF blocks plugin. https://blocks.wp.a2z/oik-plugins/acf-blocks/

To discuss this further I suggest you join the UK WordPress Community Slack group and ask in the #dev channel. https://www.wp-pompey.org.uk/clink/uk-wordpress-community-slack/

Belinda demonstrated setting foreground and background colours for a variety of blocks. She also covered the Text colour icon for selections of text in rich text blocks such as the Paragraph and Heading blocks.
She didn’t address gradients, which can be used in blocks such as Buttons and Media and Text blocks and as the background to Groups.
Gutenberg also has considersation for working with Dark Mode.

It depends how tied in you are to the look and feel of the theme and how much work you are prepared to do to migrate your content, if a migration process is required. We really need to know more about the theme you’re actually using; there are multiple themes called Evolve.

The default heading level is H2. You can choose the font size for each heading block.

See below.

You should be able to Undo your changes using the Undo icon in the top toolbar.
If you’ve already saved the post then you may be able to use Revision history to recover to a previous version. That option may not be available if you’re still working with a Draft version.

A new version of the image is created for each completed action. You may notice multiple images in your media library. Some of them will appear to be attached to the post where you uploaded it, others may appear to be unattached.

You can create a Reusable block from a selection of blocks and use them in the same post, or other posts. Edit a reusable block using the Manage all reusable blocks link, found in the Reusable tab of the block inserter. When you change a reusable block then the effect is seen wherever it’s used.

Yes, mostly. The block editor functionality is provided by WordPress core. Some stuff (such as Align wide and Align full ) has to be enabled by the theme or plugin. Other functionality may be restricted by the theme or plugin to particular user capabilities and/or post types. Users also have the option to use the Block Manager, from More Options and Tools to select the blocks they can choose from. Whether or not the block looks right on the front end depends on the theme. In some themes, developed without awareness of Gutenberg blocks, the theme’s CSS can prevent certain styles from displaying as intended.

Yes. This is it.
