While going through a CSS tutorial, I encountered this detailed definition:
.content div {
-moz-box-shadow:inset 0px 1px 0px 0px #ffffff;
-webkit-box-shadow:inset 0px 1px 0px 0px #ffffff;
box-shadow:inset 0px 1px 0px 0px #ffffff;
background:-webkit-gradient( linear, left top, left bottom, color-stop(0.05, #ededed), color-stop(1, #dfdfdf) );
background:-moz-linear-gradient( center top, #ededed 5%, #dfdfdf 100% );
filter:progid:DXImageTransform.Microsoft.gradient(startColorstr='#ededed', endColorstr='#dfdfdf');
background-color:#ededed;
-webkit-border-top-left-radius:6px;
-moz-border-radius-topleft:6px;
border-top-left-radius:6px;
-webkit-border-top-right-radius:6px;
-moz-border-radius-topright:6px;
border-top-right-radius:6px;
-webkit-border-bottom-right-radius:6px;
-moz-border-radius-bottomright:6px;
border-bottom-right-radius:6px;
-webkit-border-bottom-left-radius:6px;
-moz-border-radius-bottomleft:6px;
border-bottom-left-radius:6px;
text-indent:0;
border:1px solid #dcdcdc;
display:inline-block;
color:#777777;
font-family:arial;
font-size:15px;
font-weight:bold;
font-style:normal;
line-height:50px;
text-decoration:none;
text-align:left;
text-shadow:1px 1px 0px #ffffff;
}
The amount of code required to style a simple DIV tag can seem overwhelming. Is it really necessary to learn and implement all these styles?
