Flip what??

• border-top-left-radius <-> border-top-right-radius
• border-left-color <-> border-right-color
• border-left-style <-> border-right-style
• border-left-width <-> border-right-width
• left <-> right
• margin-left <-> margin-right

    /* x, y, ... */
    box-shadow: 1px 2px 3px #000; /* <-> */ box-shadow: -1px 2px 3px #000;
    clear: left; /* <-> */ clear: right;
    float: left; /* <-> */ float: right;
    text-align: left; /* <-> */ text-align: right;
    direction: ltr; /* <-> */ direction: rtl;
    transition: left 0.3s; /* <-> */ transition: right 0.3s;
    transition-property: left; /* <-> */ transition-property: right;
    /* transform : discribed below... */
}

Transform:

.some-element {
    /* x */
    transform: translateX(50px); /* <-> */ transform: translateX(-50px);
    /* x, y */
    transform: translate(20px, 60px); /* <-> */ transform: translate(-20px, 60px);
    /* x, y, z */
    transform: translate3d(20px, 60px, 45px); /* <-> */ transform: translate3d(-20px, 60px, 45px);
    /*x-angle, y-angle*/
    transform: skew(10deg, -30deg); /* <-> */ transform: skew(-10deg, 30deg);
    /* angle*/
    transform: skewX(-40deg); /* <-> */ transform: skewX(40deg);
    transform: skewY(85deg); /* <-> */ transform: skewY(-85deg);
    /* angle */
    transform: rotate(37deg); /* <-> */ transform: rotate(-37deg);
    transform: rotateX(52deg); /* <-> */ transform: rotateX(-52deg);
    transform: rotateY(-70deg); /* <-> */ transform: rotateY(70deg);
    transform: rotateZ(112deg); /* <-> */ transform: rotateZ(-112deg);
    /* x, y, z, angle */
    transform: rotate3d(0, 1, 0, 54deg); /* <-> */ transform: rotate3d(0, 1, 0, -54deg);
    /* not supported! */
    transform: matrix(...);
    transform: matrix3d(...);
}

To-Do List:

• Support what not supported
• Support less
• Use PHPUnit and make tests
• Color gradient
• Properties after !important will not be flipped!!! [Bug]
