Why Does Content Not Prevent Parent Div from Shrinking?

In the provided HTML code, the inner

flows out of the outer

when the window is resized to a narrow size. This behavior occurs, despite the outer

having a specific width and the inner

containing a significant amount of content.

The underlying issue is that the outer

is set as a block-level element by default. This means it takes up the entire available width of its parent element. Even with content inside, the outer

can shrink to accommodate the window size.

Combining Inline-Block and Min-Width

To prevent the outer

from shrinking, you can combine the following properties:

1. Inline-block: This allows the outer

to behave like an inline element, taking up only the width necessary to fit its content.

2. Min-width:100%: This ensures that the outer

has a minimum width equal to 100% of its parent element. This prevents it from shrinking below the width of its content.

Updated Code

Here's the updated CSS code with the recommended changes:

.demo {
  display: inline-block;
  min-width: 100%;
}

Copy after login

With these changes in place, the outer

will now remain at least as wide as its content, regardless of the width of the window.
