What are Vendor-Prefixed CSS Properties like -moz- and -webkit-, and how should they be used?

Vendor-Prefixed CSS Properties: Unraveling -moz- and -webkit-

In the realm of CSS, you may have encountered enigmatic CSS lines like these:

-webkit-column-count: 3;
-webkit-column-gap: 10px;
-webkit-column-fill: auto;
-moz-column-count: 3;
-moz-column-gap: 10px;
-moz-column-fill: auto;

These are not ordinary CSS properties. They bear the prefixes "-moz-" and "-webkit-". Let's delve into their purpose and usage.

Vendor Prefixes: A Bridge Across Browser Boundaries

Vendor prefixes, such as "-moz-" and "-webkit-", are used by rendering engines like Chrome, Safari, and Firefox to implement experimental or proprietary CSS features before their finalization in the W3C (World Wide Web Consortium) standards.

Why Use Vendor Prefixes?

Vendor prefixes enable developers to utilize innovative CSS capabilities even before they are universally supported. However, it's crucial to understand that these prefixed properties are browser-specific; they won't work in all browsers.

Best Practices When Using Vendor Prefixes

It's good practice to use vendor-prefixed versions of properties first, followed by the non-prefixed version. This ensures that when the non-prefixed property is fully implemented, it will override the vendor-prefixed settings.

Example:

.elementClass {
    -moz-border-radius: 2em;
    -ms-border-radius: 2em;
    -o-border-radius: 2em;
    -webkit-border-radius: 2em;
    border-radius: 2em;
}

Explanation of Your Specific CSS:

The CSS lines you provided set the column-count, column-gap, and column-fill properties for Firefox and WebKit browsers. By specifying the vendor-prefixed properties, you ensure that the columns are displayed correctly in these browsers.

Conclusion

Understanding vendor prefixes and their usage allows web developers to harness the latest CSS features while maintaining backward compatibility. By following best practices, you can seamlessly implement cutting-edge CSS across different browsers.
