Is my CSS shorthand correct?

.text {
 font-family: 'tahoma';
 font-size: 12px;
 line-height: 15px;
 font-weight: 500;
 display: block;
 border-style: solid;
 border-top-width: 0px;
 border-left-width: 10px;
 border-right-width: 0px;
 border-bottom-width: 5px;
 border-color: #000;
 margin-left: 10px;
 margin-top: 0;
 margin-right: 10px;
 margin-bottom: 0;
}

.text { 
font: 500 12px/15px tahoma;
display: block;
border: solid black;
border-width: 0px 0px 5px 10px; 
margin: 0px 10px 0px 10px; 
}
