Want to get header shape like that. Don't want to use png. I know that there is the way to create triangle:
#triangle-down {
width: 0;
height: 0;
border-left: 50px solid transparent;
border-right: 50px solid transparent;
border-top: 100px solid red;
}
But is there proper way to get pentagon like that, for header? Or only png will help me in this situation?
