How to Shrink a DIV to Fit Wrapped Text with JavaScript?

Resolving DIV Expansion Issue with Wrapped Text Using JavaScript

The challenge of shrinking a DIV to fit text that wraps to its maximum width is prevalent when working with CSS alone. To overcome this hurdle and achieve a perfectly centered DIV, implementing JavaScript is an effective solution.

As illustrated in the provided jsfiddle, the excessive right-hand margin around the wrapped text is due to the DIV maintaining its initial width set by the max-width property. To rectify this, we employ the following JavaScript approach:

1. Create a Range: Using document.createRange(), we create a range object that encompasses the text within the targeted DIV.
2. Set Range Boundaries: The setStartBefore and setEndAfter methods define the start and end points of the range to the beginning and end of the text, respectively.
3. Get Bounding Client Rectangle: The getBoundingClientRect() method retrieves the dimensions of the text within the range.
4. Update DIV Width: The width of the DIV is dynamically updated using the retrieved client rectangle width, ensuring the DIV adapts to the exact width of the text even when wrapped.

By implementing this JavaScript solution, you can effectively shrink the DIV to match the wrapped text, resulting in a centered and visually pleasing layout.
