404 Page Shows Unwanted Horizontal Scrollbar on Desktop

[dvpatel]

On desktop screens, the 404 error page is not displaying properly. A horizontal scrollbar appears at the bottom, indicating that some element is overflowing the viewport width. This breaks the clean layout and may indicate a CSS issue related to width, margin, or positioning.

Steps to Reproduce:

1. Go to any invalid route to trigger the 404 page (​https://wordpress.org/404/)
2. On a desktop browser (e.g., 1920×1080 screen), observe the bottom of the page.
3. Notice that a horizontal scroll bar is visible.

Expected Behavior

The 404 page should fit entirely within the viewport width without causing horizontal scrolling on desktop. All content should be responsive and centered or aligned properly.
