I am trying to find out what is the “best” approach.
To know systematically for a new section I create a container in which I will insert all the other blocks (container, grid, other blocks …)
Or if I use a grid, can I insert it directly into the page without putting it in a container?
For shortcodes (WP_Show_Post) or for a Slider block (SmartSlider) insert them directly or put them in a container? a grid?
In an article I had read below. Is it correct?
"What is the difference between the Container and the Grid block? Every column on your grid has a container block, and you can place your content blocks on that container.
But the container block can have its own styling options, like custom font, a background gradient, and so on.
By default, the grid is using a 100% width of your screen (full-width-design). If you do not want that, you can add a container first and place a grid on the container."
