CSS 幻灯片不会滑动，而只是显示

CSS slide does not slide, but just appears

本文关键字：显示 幻灯片 CSS      更新时间：2023-09-26

我试图让div#project-wrapper在单击a.post-link时向下滑动，此时div.post-container通过JS添加fadeOutDown类并从顶部淡入。我遇到了几个问题：

1） div#project-wrapper ，它获取通过 JS 添加的activated类，在单击a.post-link时不会向下滑动。相反，它只是出现。

2）fadeOutDown类被添加到.post-container但div不执行我编写的任何CSS动画。

有人可以帮我解决这个问题吗？

.JS

$('.post-link').click(function(e) {
    e.preventDefault();
    function projectShow() {
        $('#project-wrapper').addClass('activated');
        $('.post-container').addClass('fadeOutDown');
    }
    if ($(window).scrollTop() != 0) {
        $('html, body').animate({
            scrollTop : 0
        },500, projectShow);
    } else {
        projectShow();
    }
});

这并不能解决第一个问题，但第二个问题是因为你没有给动画时间。看到编辑我也想出了第一部分小提琴

$('.post-link').click(function(e) {
    e.preventDefault();
    
    function projectShow() {
        $('#project-wrapper').addClass('activated' );
        $('.post-container').addClass('fadeOutDown');
    }
    
    if ($(window).scrollTop() != 0) {
        $('html, body').animate({
            scrollTop : 0
        },500, projectShow);
    } else {
        projectShow();
    }
});

编辑 小提琴

我从这里删除了display:block

#project-wrapper.activated {
transform: translateY(0);
}

我像这样编辑了jQuery。

 function projectShow() {
    $('#project-wrapper').show(500);
    $('#project-wrapper').addClass('activated');
    $('.post-container').addClass('fadeOutDown');
}


$('.post-link').click(function (e) {
    e.preventDefault();
    function projectShow() {
        $('#project-wrapper').show(500);
        $('#project-wrapper').addClass('activated');
        $('.post-container').addClass('fadeOutDown');
    }
    if ($(window).scrollTop() != 0) {
        $('html, body').animate({
            scrollTop: 0
        }, 500, projectShow);
    } else {
        projectShow();
    }
});
#project-wrapper {
    background: #000;
    color: #fff;
    display: none;
    margin: 0 1%;
    position: relative;
    transform: translateY(-100%);
    -webkit-transition: all 0.5s cubic-bezier(0, 1, 0.5, 1);
    transition: all 0.5s cubic-bezier(0, 1, 0.5, 1);
}
#project-wrapper.activated {
    
    transform: translateY(0);
}
#project-wrapper #loading-animation {
    display: none;
    left: 0;
    position: absolute;
    top: 0;
}
#project-wrapper #project-container {
    overflow: hidden;
    padding: 40px;
}
@-webkit-keyframes fadeOutDown {
    0% {
        opacity: 0;
        -webkit-transform: translate(0, -10px);
        transform: translate(0, -10px);
    }
    100% {
        opacity: 1;
        -webkit-transform: translate(0, 0);
        transform: translate(0, 0);
    }

    }
}
.fadeOutDown {
    -webkit-animation: fadeOutDown 5s;
    animation: fadeOutDown 5s;
}
#project-wrapper #project-container .post-container #project-left-content {

由于您使用的是jquery，因此您可以省去一些麻烦和所有这些css，并使用如下所示的内容：

function projectShow() {
    $('#project-wrapper').slideDown();
    $('.post-container').hide().fadeIn();
}
