To divide a Space, click on it, then click on the table icon. You'll see the list of the divided spaces. You can fill the spaces with text, images, links, etc.
See the example. Open a new page, click on the space, add a card there, delete the header, the footer, and set the card's width to 500px. Align the card to the center horizontally and vertically. Then, select the space in the card, and select a table icon. You've just divided the space. Now, you can add images, text, inputs, radio buttons there.
