解决方案
这是因为您的css被默认的引导程序css覆盖。
您只需进行一项更改。使用 .navbar.navbar-default 而不是 .navbar-default 无处不在，这会让您的css偏好超过默认CSS。
下面是关于css特性的一篇很好的文章：
.navbar.navbar-default {background-color：#ffffff; navbar.navbar-default .navbar-brand {color：＃292929;}。navbar.navbar-default .navbar-brand：hover，.navbar.navbar-default .navbar-brand：focus -navbar-brand：border-color：#ffffff;}。 {color：＃ffd4d4;}。navbar.navbar-default .navbar-text {color：＃292929;}。navbar.navbar-default .navbar-nav> li> {color：＃292929;}。navbar.navbar-default .navbar-nav> li> a：悬停，.navbar.navbar-default .navbar-nav> li> a：focus {color：＃ffd4d4;}。navbar.navbar-default .navbar-nav> .active> a，.navbar.navbar-default .navbar-nav> .active> a：悬停，.navbar.navbar-default .navbar-nav> .active> a：focus {color：＃ffd4d4; background-color：#ffffff;}。navbar.navbar-default .navbar-nav> .open> a，.navbar.navbar-default .navbar-nav> .open> a：悬停，.navbar.navbar-default .navbar-nav> .open> a：focus {color：＃ffd4d4; navbar.navbar-default .navbar-toggle {border-color：#ffffff;}。navbar.navbar-default .navbar-toggle：悬停，.navbar.navbar-default .navbar-toggle ：focus {background-color：#ffffff;}。navbar.navbar-default .navbar-toggle .icon-bar {background-color：＃292929;}。navbar.navbar-default .navbar-collapse，.navbar.navbar- navbar.navbar-default .navbar-link {color：＃292929;}。navbar.navbar-default .navbar-link：hover {color：＃ffd4d4;}。navbar-品牌{transform：translateX（-50％）;剩下：50％; position：absolute;}。nav.navbar-nav> li.navbar-left {font-family：'Nunito Sans'，sans-serif; navbar-brand {padding：0px;}。navbar-brand> img {height：90％; font-size：11px;}。 width：auto;}。banner {width：100％; / * background-color：＃c3d7df; * /}。banner-inner {max-width：1100px; margin：0 auto;} @ media（min-width：768px）和（max-width：991px）{.container.navbar-container {width：100％;填充：0; }} < script src =https：// ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js\"></script><!DOCTYPE html>< html lang =en>< head> < meta charset =utf-8/> < meta name =viewportcontent =width = device = width，initial-scale = 1.0> <标题>我的网站< / title> < link rel =stylesheethref =https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css> < link rel =stylesheettype =text / csshref =style.css/> < link href =https://fonts.googleapis.com/css?family=Nunito|Nunito+Sans|Playfair+Display =stylesheet> <！ - 最新编译和缩小的CSS - > < link rel =stylesheethref =https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.cssintegrity =sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va + PmSTsz / K68vbdEjh4ucrossorigin =anonymous > <！ - 最新编译和缩小的JavaScript - > < script src =https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.jsintegrity =sha384-Tc5IQib027qvyjSMfHjOMaLkfuWVxZxUPnCJA7l2mCWNIpG9mGCD8wGNIcPD7Txacrossorigin =anonymous>< / script> < /头><身体GT; <报头GT; < div class =container navbar-container> < nav class =navbar navbar-default> < div class =container-fluid> < div class =navbar-header> < button type =buttonclass =navbar-toggle collapseddata-toggle =collapsedata-target =＃navbar> < span class =sr-only>切换导航< / span> < span class =icon-bar>< / span> < span class =icon-bar>< / span> < span class =icon-bar>< / span> < /按钮> < a class =navbar-brandhref =http://jh.com>< img class =logosrc =http://images.financialexpress.com/2015/12/Lead- image.jpg的>< / A> < / DIV> < div id =navbarclass =navbar-collapse collapse> < ul class =nav navbar-nav> < li class =navbar-left>< a href =index.html> TRAVEL< / a>< / li> < li class =navbar-left>< a href =＃>激励与LT; / A>< /锂> < li class =navbar-left>< a href =＃> PORTFOLIO< / a>< / li> < li class =navbar-left>< a href =＃>关于< / a>< / li> < / UL> < ul class =nav navbar-nav navbar-right> <李> < a href =https://www.instagram.com>< i class =fa fa-instagram>< / i>< / a> <李> < a href =https://www.pinterest.com>< i class =fa fa-pinterest>< / i>< / a> <李> < a href =https://www.facebook.com>< i class =fa fa-facebook>< / i>< / a> <李> < a href =https://twitter.com>< i class =fa fa-twitter>< / i>< / a> < / UL> < / DIV> <！ - /。nav-collapse - > < / DIV> <！ - /。container-fluid - > < / NAV>< / DIV> < / header><！--- End Header - > < section class =banner> < div class =banner-inner> < img class =bannersrc =img / background.png> < / DIV> <！--- End Banner - >< / body>< / html>

This is happening because your css is being overwritten by the default bootstrap css.
You need to make only one change. Use .navbar.navbar-default instead of just .navbar-default everywhere, this will give your css preference over the default css.
Here's a good article on css specificity : https://css-tricks.com/specifics-on-css-specificity/
.navbar.navbar-default {
background-color: #ffffff;
border-color: #ffffff;
}
.navbar.navbar-default .navbar-brand {

.navbar.navbar-default .navbar-brand:focus {

.navbar.navbar-default .navbar-nav > li > a {
