Why Do Input Borders Disappear When Zooming in Chrome?

Chrome Zoom Issue: Input Borders Disappear

Users have encountered a perplexing issue in Google Chrome, where input borders vanish when zooming in or out. This issue has surfaced on forums, leaving users seeking solutions.

The problem arises when zooming in using Chrome, resulting in the disappearance of input borders. This behavior has been observed on certain websites and can vary depending on the zoom level.

Solution: CSS Modification for Border Thickness

A straightforward solution to this issue involves modifying the CSS for the borders. Specifically, changing the border thickness from a fixed value to "thin" resolves the problem.

For instance, if the CSS originally included the following code:

INPUT,TEXTAREA {
  border-top: 1px solid #aaa
}

Replacing it with the following code corrects the issue:

INPUT,TEXTAREA {
  border-top: thin solid #aaa
}

Chrome Bug or CSS Issue?

The root cause of this behavior is unclear. While some speculate that it may be a Chrome bug, others suggest that the problem lies with the CSS used to define the borders.

Changing the border thickness to "thin" seems to effectively resolve the issue, suggesting that the problem is related to the rendering of thin borders in Chrome.
