I have a box which contain a simple header and footer. The problem is that appears a scrollbar at the bottom which I don't wont. I know that is very stupid as question but I don't figure out how to fix it.
.box{
    width: 100%;
    height: 100%;
}
.header {
    background: tomato;
    position: absolute;
    top: 0;
    width: 100%;
    height: 5%;
}
.footer {
    background: lightgreen;
    position: absolute;
    bottom: 0;
    width: 100%;
    height: 5%;
}
