In früheren Tests wurde die Konsole zum Generieren von HTML-Tags verwendet. Die generierten HTML-Tags können auf der Seite angezeigt werden und der Effekt ist wie folgt:

css

* { 
    /* old-style reset here :) */ 
    border: 0px; 
    padding: 0px; 
} 
body { 
    font-family: Helvetica; 
    background: white; 
    text-align: center; 
    /* background: url(../img/body.png) repeat-x; */} 
body h1 { 
    padding-top: 20px; 
    font-size: 36px; 
    color: #335; 
} 
p{font-size:26px;} 
table { 
    border-collapse: separate; 
    border: 1px solid #9DABCE; 
    border-width: 1px 1px 1px 1px; 
    margin: 10px auto; 
    font-size: 30px; 
} 
   
   
td, th { 
    width: 81px; 
    height: 81px; 
    text-align: center; 
    vertical-align: middle; 
    /*background: url(../img/cells.png);*/ 
    color: #444; 
    position: relative; 
} 
th { 
    height: 30px; 
    font-weight: bold; 
    font-size: 14px; 
} 
   
td.sign_in { 
    background-position: 81px 0px; 
    color: red; 
}
