You need to have the .headerContent
inside of the .bluebackgroundtop
div, and then style like this:
* {
padding: 0;
margin: 0;
}
.headercontent {
height: 150px;
width: 950px;
margin:0 auto;
text-align:center;
}
.bluebackgroundtop {
height: 150px;
width: 1920px;
margin:0 auto;
background-color: #3c56a6;
}
