css

.header /* header settings */ {     background-color:#000 !important; /*background color black*/     color:#fff !important; /*font color white*/     height:200px; /*height of whole element*/     font-family:impact, charcoal, sans-serif; /*font of text*/ }  body /*background of page*/ {     background:#ffb3b3 !important; /*background color of whole page*/ }

please me this looks ugly.

because have .jumbotron class has margin-bottom:30px default in bootstrap.

so need reset it, using margin-bottom:0

note:

  • avoid using !important , bad practice.
  • you have 2 bootstrap-min.js files, when need one.

.header {    /* header settings */    background-color: #000    /*background color black*/    color: #fff    /*font color white*/    height: 200px;    /*height of whole element*/    font-family: impact, charcoal, sans-serif;    /*font of text*/  }  body {    /*background of page*/    background: #ffb3b3    /*background color of whole page*/  }  .body .jumbotron {    margin-bottom: 0  }
