Was wondering if anyone's done the style and what the code is?

I've also seen some great hover over buttons and wondered whether they're two images blending or what not?

try 

.sqs-block-button-element:hover {
    -webkit-transform: translate(0px,-5px);
    -moz-transform: translate(0px,-5px);
    -ms-transform: translate(0px,-5px);
    -o-transform: translate(0px,-5px);
    transform: translate(0px,-5px);
    opacity: .9 !important;
    border-radius: 30px 30px 30px 0px !important;
}
.sqs-block-button-element {
    -webkit-transition: all .3s ease-out !important;
    -moz-transition: all .3s ease-out !important;
    -ms-transition: all .3s ease-out !important;
    -o-transition: all .3s ease-out !important;
    transition: all .3s ease-out !important;
    transition-property: all !important;
    transition-duration: 0.3s !important;
    transition-timing-function: ease-out !important;
    transition-delay: 0s !important;
}
