Why Doesn't My Outer `` Fully Enclose My Inner `` on Window Resize?

Why Does the Outer

Fail to Fully Surround the Inner

When the Window Narrows?

This issue arises from the interaction between different CSS properties and the element's display settings. By default, block-level elements, like

, will expand to fill the available width of their containing block. In this case, the outer

is a block-level element within a wider containing block.

To prevent the outer

from shrinking below the width of the inner

, a combination of inline-block and min-width properties can be utilized. Here's the explanation:

• inline-block: This display value allows an element to act like an inline element while retaining the ability to define specific width and height. This prevents the element from breaking onto a new line and keeps it contained within its parent element.
• min-width: 100%: By setting the min-width of the outer
  to 100%, we ensure that it will never shrink below the width of its content. This prevents the inner

  from escaping beyond the boundaries of the outer

  when the window narrows.

  By incorporating inline-block display and min-width, we can constrain the outer

  to hug the width of the inner

  while maintaining its block-level behavior.
