Why does css write the right trapezoidal page style but not print it to A4 paper?
css code: 

<style>
    .tab { 
        position: relative; 
        display: inline-block;
         padding: .5em 1em .35em; 
    } 
    .tab::before { 
        content: ""; /* To generate the box */ 
        position: absolute; top: 0; right: 0; bottom: 0; left: 0; 
        z-index: -1; 
        background: -sharpfff; 
        border: 5px solid pink; 
        transform: perspective(.5em) rotateX(5deg);
    }
    </style>
