Basically, when I hover, I want the effect to look like this:

My website is here

The code is as followsIgnore! important:

.cta-button-menu, .cta-button-menu::before {
        transition:all 0.3s linear !important;
        width: 120px !important;
        height: 50px !important;
        display: inline-flex !important;
        justify-content: center !important;
        align-items: center !important;
    }
    .cta-button-menu:hover {
        transform:rotateZ(-45deg) !important;
        background: #21B6CD !important;
        color: white !important;
    }
    .cta-button-menu::before {
        content:"Book Now" !important;
        background-color:transparent !important;
        position:absolute !important;
        @include main-font($white, 16px !important, $font-bold !important);
      }
    .cta-button-menu:hover::before{
        transform: rotateZ(90deg) !important;
        background-color:#e72f54 !important;
        border:none !important;
    }

For some reason I can't get the blue button to overlap the red button. Can't figure it out
