What best practices can be implemented to ensure compatibility with IE9 and higher for CSS styles, especially regarding border radius?

When working with CSS styles, particularly border radius, to ensure compatibility with IE9 and higher, it is recommended to use vendor prefixes such as -webkit- and -moz- for older versions of Internet Explorer. Additionally, using a CSS preprocessor like Sass or Less can help streamline the process of adding vendor prefixes automatically.

<style>
    .example {
        border-radius: 5px;
        -webkit-border-radius: 5px;
        -moz-border-radius: 5px;
    }
</style>
