Modernize Your CSS by Removing Outdated Vendor Prefixes

CSS Analyzer

What is this warning?

Your stylesheet includes old 'vendor prefixes' (like `-webkit-` or `-moz-`). These were used in the past to make new CSS features work in specific browsers. Today, most of these are no longer needed and just add extra weight to your files. It's time for a little spring cleaning!

border-radius: 5px;

The Solution

Remove the old prefixes and just use the standard property. For ensuring compatibility with older browsers, it's best to use a tool like Autoprefixer in your development process, which automatically adds only the prefixes that are still necessary.
