Tell me, I do not fully understand how the div layout works. When you make up a page, often one div happens inside another diva. And I just can not figure out how to make one diva block which, for example, I create to create a background for an internal block with text, stretch like an internal div. But it turns out that these divas are like sheets of paper on the table - one easily goes beyond the other. How can I make the size of an external diva increase automatically with an increase in the internal one (so that they are mutually dependent blocks, so that the internal one cannot go beyond the external one).
