How Can I Make a Div's Background Transparent While Keeping Text Opaque in All Browsers?

Opacity Effects on Background-Color without Impacting Text

Achieving transparency in a div's background while maintaining opaque text requires a cross-browser solution that addresses Internet Explorer 6.

To accomplish this without external libraries:

• Utilize rgba: RGBa values allow for specifying transparency (opacity) in addition to color values.

.alpha60 {
    background-color: rgba(0, 0, 0, 0.6);
}

• Counteract IE behavior: Internet Explorer requires additional filters to support RGBa transparency.

.alpha60 {
    filter:progid:DXImageTransform.Microsoft.gradient(startColorstr=#99000000, endColorstr=#99000000);
    -ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr=#99000000, endColorstr=#99000000)";
}

• Handle IE background inheritance: To prevent opacity being inherited by child elements in IE, declare background: transparent. This is best done using conditional comments.
