title: What CSS3 features still need vendor prefixes?
body: <p>The most common features I remember needing prefixes for were features such as <code>flexbox</code>, <code>border-radius</code>, <code>box-shadow</code>, etc... but now they are supported. With more users switching to more powerful browsers like Chrome and Firefox and away from IE, are there still features now that haven't been fully supported and require prefixes?</p>
