To detect multiple features at once, use the and operator.


         @supports (transform: translateZ(1px)) and (transform-style: preserve-3d) and (perspective:
         1px) {
           /* Probably do some fancy 3d stuff here */
         }


        There is also an or operator and a not operator:


         @supports (display: flex) or (display: table-cell) {
           /* Will be used if the browser supports flexbox or display: table-cell */
         }
         @supports not (-webkit-transform: translate(0, 0, 0)) {
           /* Will *not* be used if the browser supports -webkit-transform: translate(...) */
         }


        For the ultimate @supports experience, try grouping logical expressions with parenthesis:


         @supports ((display: block) and (zoom: 1)) or ((display: flex) and (not (display: table-
         cell))) or (transform: translateX(1px)) {
           /* ... */
         }


        This will work if the browser

            1.  Supports display: block AND zoom: 1, or
            2.  Supports display: flex AND NOT display: table-cell, or
            3.  Supports transform: translateX(1px).
