How to set a property to a block so that the text cannot crawl out of it?

Question

css

There is text in the block if you set margin:200px;
then the text tag will fly outside the block and will not be visible, how to make it so that for any maximum indentation value this text does not fly outside the block?

Answer 1

Everything is fine.

Answer 2

The block is probably also given a height, so the text has nowhere else to go but disappear. Either get rid of the height (height), or set the block to overflow: auto;
