The new block-based editor won&#8217;t change the way any of your content looks to your visitors. What it will do is let you insert any type of multimedia in a snap and rearrange to your heart&#8217;s content. Each piece of content will be in its own block; a distinct wrapper for easy maneuvering. If you&#8217;re more of an HTML and CSS sort of person, then the blocks won&#8217;t stand in your way. WordPress is here to simplify the process, not the outcome.
