How Do CSS `width: auto` and `max-width` Affect Tooltip Content Overflow and Wrapping?

Tooltip Content Overflow Behavior

When creating a tooltip with CSS, you might expect the width to adjust automatically to accommodate the length of the content, with boundaries set by the min-width and max-width properties. However, the behavior differs when the content wraps onto multiple lines.

Issue and Behavior

The issue arises from setting both width: auto and max-width: 250px. While width: auto allows the tooltip to shrink to fit the content, max-width limits its expansion to 250px. This behavior is evident when a long word at the end of a line causes the text to wrap, leaving noticeable padding on the right side of the tooltip.

Explanation

A browser calculates the tooltip's width by attempting to flow the text within the maximum allowed width (250px). Any excess text wraps to subsequent lines. However, once the text wraps, the box's width is fixed at 250px because that is the maximum specified in the CSS. It does not shrink to accommodate the reduced text width after wrapping.

Resolution

Unfortunately, there is no straightforward solution to modify this behavior. Text wrapping inherently doesn't allow for the box to shrink after line breaks. Therefore, the expected shrinking or growing effect cannot be achieved using these CSS properties.
