How Should Vendor-Specific CSS Declarations Be Ordered for Optimal Browser Compatibility?

Vendor-Specific CSS Declaration Ordering

The ordering of vendor-specific CSS declarations can significantly impact how browsers interpret and apply styles. Browser-specific prefixes, such as "-moz-" and "-webkit-", are used to provide vendor-specific implementations of features that may not yet be part of the W3C standard.

When using vendor-specific CSS, it's important to consider the order in which the declarations appear. The most effective practice is to place the standard, unprefixed property last:

.foo {
    -moz-border-radius: 10px;    /* Mozilla */
    -webkit-border-radius: 10px; /* Webkit */
    border-radius: 10px;         /* W3C */
}

Placing the standard property last ensures its application if a browser supports it. This approach minimizes inconsistencies between browsers and ensures that the W3C implementation takes precedence whenever available.

Browser-specific prefix notation, such as "-webkit-" or "-moz-", denotes experimental implementations that may diverge from the specification. By prioritizing the standard property, you ensure consistency and conformity with the industry-agreed standards.
