index.css

.container-fluid { padding-left: 200px;}.navbar-default { background-color: #308dca;}.navbar-brand { font-size: 34px; height: 70px;}.navbar-nav>li>a { font-size: 19px;}.navbar-default .navbar-brand, .navbar-default .navbar-nav>li>a, .navbar-default .navbar-nav>li>a:hover, .navbar-default .navbar-nav>li>a:focus { color: #fff;}.navbar-brand, .navbar-nav>li>a { line-height: 40px;}.navbar-default .navbar-nav>.active>a, .navbar-default .navbar-nav>.active>a:hover, .navbar-default .navbar-nav>.active>a:focus { color: #fff; background-color: #2276bf;}.index-body { margin: 0 auto;}.carousel-inner { height: 490px;}.index-body, .images { width: 900px;}.index-footer { margin-top: 20px; color: #fff; background-color: #2276bf;}.footer-centent { width: 300px; font-size: 20px; line-height: 55px; margin: 0 auto; height: 60px;}
