Why is the object not stretching?

Question

css

There is an example . It shows a .sector stretching issue in the bottom box with scrolling due to overflow. Those. .sector adjusts to the parent when it overflows. How to make .sector go beyond .house?

Answer 1

If you use float, then if there is not enough space in the width, the block will go down. And your available width is 400px-2px(border)
Use inline-block in conjunction with nowrap for .block. Example
Or use inline-flex for .sector. Example
