我正试图让两个并排的盒子占据屏幕的整个宽度.但是,当将宽度设置为50%时,每个盒子要扩展大约10px,宽度大于50%.我究竟做错了什么?
#sides {
padding-top: 40px;
padding-bottom: 40px;
background-color: white;
}
#leftside {
width: 50%;
background-color: grey;
padding: 20px;
margin: 0px;
position: relative;
}
#rightside {
width: 50%;
display: inline-table;
background-color: #018DCA;
float: left;
padding: 20px;
margin-left: 50%;
position: relative;
}
