This behavior disparity, evident in elements like input boxes, poses challenges in ensuring a consistent user experience across different platforms.

To address this issue, it's crucial to understand where these default CSS rules reside. While the solution of a CSS reset might seem tempting, it often eliminates essential styling that contributes to the desired appearance and functionality of your website.

Fortunately, there are resources available to guide you through the intricacies of browsers' default CSS:
