What are -webkit- and -moz- Prefixes in CSS and How Should They Be Used?

Understanding -moz- and -webkit- Prefixes

When encountering CSS code with prefixes like "-webkit-" or "-moz-", it's essential to comprehend their purpose. These prefixes are vendor-specific properties that allow for the implementation of emerging or proprietary CSS features before their standardization by the W3.

Benefits of Vendor Prefixes

These prefixes enable browsers to test new features and account for inconsistencies in different rendering engines. As browser compatibility improves, the prefixes are gradually removed once the final versions of the properties are supported.

Best Practices for Using Prefixes

It's recommended to use vendor-prefixed versions of properties first and then follow up with the non-prefixed versions. This ensures that the non-prefixed property will override the prefixed settings once supported in the browser. For example:

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

Specific Example

In your provided CSS code:

-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 prefixed properties set the column-count, column-gap, and column-fill attributes for Webkit browsers and Firefox.
