The block editor does not provide this functionality. Blocks can only be moved up and down, and if you want to resize them you will need to set the dimensions in pixels or percentage.
Customization options for individual elements are also much more complete in page builders than in the block editor . Gutenberg allows you to set text colors, background colors, size, and little else. If you want to apply other styles, you denmark phone number list can use a class or an id and add custom CSS.
With a page builder, on the contrary, you have many more options: from size to margins, from position to borders, most of the customizations applicable via CSS can also be done with the element settings, simply with one click.
One of the reasons why Gutenberg is less flexible than a page builder has to do with its dependency on the theme used. As much as you can customize each individual block, you will find that if you change themes, the page and even the individual elements will look different.
