I'm having problems with Safari 5.1, the css width: calc (100% - 350px); does not work correctly on Safari, follow the code and jsfiddle:
<div id="menu"></div>
<div id="conteudo2"></div>
#conteudo2 {
width: -webkit-calc(100% - 150px);
width: -moz-calc(100% - 150px);
width: calc(100% - 150px);
background-color: #333333;
float: left;
height: 920px;
margin-top: -10px;
}
#menu {
width: 150px;
float: left;
height: 900px;
background-color: #f2f2f2;
}
In other browsers it is working correctly !!
