Unable to set DIV width to 100% and show a scrollbar

I am facing an issue with the width of a DIV element on my webpage. Despite setting it to 100% width, it only takes up the visible window's width and not the full page width, especially when a horizontal scroll bar is displayed.

Below is the HTML code snippet:

<!DOCTYPE html>
<html lang="en">
<body>

    <div style="background-color:yellow;">100% DIV</div>

    <table style="width:100%; background-color:orange;">
        <thead>
            <tr>
                <th style="padding-left:20px; padding-right:20px;">Very_Long_Header_1</th>
                <th style="padding-left:20px; padding-right:20px;">Very_Long_Header_2</th>
                <th style="padding-left:20px; padding-right:20px;">Very_Long_Header_3</th>
            </tr>
        </thead>
    </table>

</body>
</html>

When I scroll to the right, the DIV does not extend to full width as desired:

Is there a way to ensure that the DIV occupies 100% of the page width without altering the generated TABLE code?

If you're looking to have a block-level element inherit the width of its sibling without setting any specific widths and using only CSS (no JavaScript), unfortunately, that's not possible within a block-level parent element.

One workaround is to apply display: inline-block to the parent element since an inline-block element calculates its width based on its widest child.

In this scenario, it's important not to add display: inline-block directly to the body element. Instead, consider wrapping the 100% div and table elements in another container like so:

<!DOCTYPE html>
<html lang="en>
<body>
  <div class="wrapper" style="display: inline-block; min-width: 100%;">
    <div style="background-color:yellow;">100% DIV</div>
    <table style="width:100%; background-color:orange;">
      <thead>
        <tr>
          <th style="padding-left:20px; padding-right:20px;">Very_Long_Header_1</th>
          <th style="padding-left:20px; padding-right:20px;">Very_Long_Header_2</th>
          <th style="padding-left:20px; padding-right:20px;">Very_Long_Header_3</th>
        </tr>
      </thead>
    </table>
  </div>
</body>
</html>

Additionally, by adding min-width: 100% to the wrapper element, it can act like a block-level element on larger screens.

It appears that the table tag is overflowing, so you may want to assign a 100% width to its parent element and also to the containing div. If this solution doesn't work, please share a jsfiddle link with me for further assistance.
