我有一个固定顶部的导航栏,我做了一个功能,使它在滚动缩小但我有一个问题,导航栏中的ul类没有正确收缩,我给它一个行高度,以垂直对齐它navbar-brand但我无法弄清楚当导航栏缩小时如何修复,这是我的代码:
$(document).ready(function(){
var scrollTop = 0;
$(window).scroll(function(){
scrollTop = $(window).scrollTop();
$('.counter').html(scrollTop);
if (scrollTop >= 100) {
$('#global-nav').addClass('scrolled-nav');
} else if (scrollTop < 100) {
$('#global-nav').removeClass('scrolled-nav');
}
});
});
#global-nav{
height: 150px;
-webkit-transition: height .5s, line-height .5s;
transition: height .5s, line-height .5s;
}
.navbar-brand img{
height:95px;
}
.navbar-default .navbar-nav>li>a{
line-height: 95px;
}
.navbar-brand
img{
display: inline-block;
-webkit-transition: all .5s;
transition: all .5s;
}
.scrolled-nav .navbar-brand img{
height: 50px;
}
.scrolled-nav{
height: 100px !important;
line-height: 100px !important;
}
.counter{
width: 20px;
height: 20px;
background: black;
color: #fff;
position: fixed;
top: 120px;
right: 0;
}

您的问题是
.navbar-default .navbar-nav>li>a {
line-height: 95px;
}
当你考虑填充时,你需要70px
为小.navbar-default.scrolled-nav .navbar-nav>li>a {
line-height: 70px;
}
(或小时删除填充)。
简单回答:
function generateMarkup(handValue) {
if (handValue >= 0.9) {
return document.getElementById("resultText").innerHTML = "You can play any two cards from this position.";
}
if (handValue < 0.06) {
return document.getElementById("resultText").innerHTML = '<tr><td class="tooltip"><img src="' + startHand[0] + '.jpg"><span class="tooltiptext">' + toolTips[0] + '</span></td>';
}
if (handValue < 0.20) {
return document.getElementById("resultText").innerHTML = '<tr><td class="tooltip"><img src="' + startHand[0] + '.jpg"><span class="tooltiptext">' + toolTips[0] + '</span></td><td class="tooltip">' + startHand[1] + '.jpg"><span class="tooltiptext">' + toolTips[1] + '</span></td>';
}
if (handValue < 0.40) {
return document.getElementById("resultText").innerHTML = '<tr><td class="tooltip"><img src="' + startHand[0] + '.jpg"><span class="tooltiptext">' + toolTips[0] + '</span></td><td class="tooltip">' + startHand[1] + '.jpg"><span class="tooltiptext">' + toolTips[1] + '</span></td><td class="tooltip">' + startHand[2] + '.jpg"><span class="tooltiptext">' + toolTips[2] + '</span></td>';
}
return document.getElementById("resultText").innerHTML = 'You should play if your cards are in one of the following categories:<br><br><table>';
}

使用代码片段进行复制很棘手,但控制导航项高度的CSS是这样的:
.navbar-default .navbar-nav>li>a {
line-height: 95px;
}
因为此代码使用行高来使文本在导航按钮中居中,所以这是调整缩小高度所需的属性。
或者,您可以将行高与收缩导航分开并使用padding-top
和padding-bottom
,并在添加滚动类时调整这些属性。
