Your website's appearance can vary significantly across different browsers due to a variety of factors, including CSS compatibility and HTML support. Each browser interprets web standards slightly differently, leading to variations in how elements are displayed. For instance, Smashing Magazine discusses how older versions of popular browsers may lack support for specific CSS properties, causing layout discrepancies. Additionally, browser-specific settings, such as zoom levels or extensions, can further influence how a website renders, making it crucial for web developers to test their sites across multiple platforms.

Another reason for these discrepancies is the use of JavaScript and browser rendering engines. Different browsers, like Chrome, Firefox, and Safari, utilize unique rendering engines that can affect how scripts are executed and how dynamic elements are displayed. According to Mozilla Developer Network, understanding how the JavaScript execution context changes between browsers can help developers create more consistent user experiences. In addition, it's essential to regularly audit your website's design and functionality using tools like BrowserStack to ensure a seamless experience for all users, regardless of their chosen browser.
