html - 如何编辑 Bootstrap 导航栏的样式？

标签 html css twitter-bootstrap

我正在尝试编辑 Bootstrap 导航栏的样式。但是，例如，我无法编辑颜色和删除边框。我只想将颜色更改为白色，将边框颜色也更改为白色，我已经包含了下面的代码。谁能告诉我我做错了什么？

.navbar-default {
  background-color: #ffffff;
  border-color: #ffffff;
}
.navbar-default .navbar-brand {
  color: #292929;
}
.navbar-default .navbar-brand:hover,
.navbar-default .navbar-brand:focus {
  color: #ffd4d4;
}
.navbar-default .navbar-text {
  color: #292929;
}
.navbar-default .navbar-nav > li > a {
  color: #292929;
}
.navbar-default .navbar-nav > li > a:hover,
.navbar-default .navbar-nav > li > a:focus {
  color: #ffd4d4;
}
.navbar-default .navbar-nav > .active > a,
.navbar-default .navbar-nav > .active > a:hover,
.navbar-default .navbar-nav > .active > a:focus {
  color: #ffd4d4;
  background-color: #ffffff;
}
.navbar-default .navbar-nav > .open > a,
.navbar-default .navbar-nav > .open > a:hover,
.navbar-default .navbar-nav > .open > a:focus {
  color: #ffd4d4;
  background-color: #ffffff;
}
.navbar-default .navbar-toggle {
  border-color: #ffffff;
}
.navbar-default .navbar-toggle:hover,
.navbar-default .navbar-toggle:focus {
  background-color: #ffffff;
}
.navbar-default .navbar-toggle .icon-bar {
  background-color: #292929;
}
.navbar-default .navbar-collapse,
.navbar-default .navbar-form {

}
.navbar-default .navbar-link {

}
.navbar-default .navbar-link:hover {
  color: #ffd4d4;
}

  left: 50%;
  position: absolute;
}

.navbar-nav > li.navbar-left {
  font-family: 'Nunito Sans', sans-serif;
  font-size: 11px;
}

.navbar-brand {
  padding: 0px;
}
.navbar-brand>img {
  height: 90%;
  width: auto;
}

	width: 100%;
	/*background-color: #c3d7df;*/
}

.banner-inner {

最佳答案

发生这种情况是因为您的 css 被默认的 Bootstrap css 覆盖了。

您只需进行一项更改。在任何地方都使用 .navbar.navbar-default 而不是 .navbar-default，这将使您的 css 优先于默认 css。
