Question

我试图在引导程序导航栏的顶部添加图像，但是我无法添加一个附加＆＃34;条和＃34;在导航。

Answer 1

不确定图像，我不会使用百分比表示宽度，然后使用vh作为高度，因为它可能会导致失真。坚持一个并居中。

然而，链接可以使用它们所在容器的百分比宽度，以使它们按照您的设计填充整个屏幕。

Answer 2

您可以将图像构建到导航栏中，因为您使用固定位置进行导航。这篇文章也可能有助于您尝试实施的其他功能：SO Bootstrap Search Bar

$(".btn-search").click(function(e) {
  $("#search-input, #btn-go").fadeToggle();
});
$(".hasclear").keyup(function() {
  var t = $(this);
  t.next('span').toggle(Boolean(t.val()));
});

$(".clearer").hide($(this).prev('input').val());

$(".clearer").click(function() {
  $(this).prev('input').val('').focus();
  $(this).hide();
});
