我在阻止我的标题在向下滚动页面时变得透明时遇到了很多麻烦。我不确定是什么原因造成的(我使用了模板)，但您可以在此处查看代码:

我认为这与 CSS 有关，但我不确定。

问题是在顶部时，无法看到菜单项。我只希望标题保持黑色。你可以在这里看到问题:

最佳答案

在您的 scripts.js 文件中，有一个函数可以在滚动条上添加或删除一些内容。

/***************** Header BG Scroll ******************/

    $(function() {
        $(window).scroll(function() {
            var scroll = $(window).scrollTop();

            if (scroll >= 20) {
                $('section.navigation').addClass('fixed');
                $('header').css({
                    "border-bottom": "none",
                    "padding": "35px 0"
                });
                $('header .member-actions').css({
                    "top": "26px",
                });
                $('header .navicon').css({
                    "top": "34px",
                });
            } else {
                $('section.navigation').removeClass('fixed');
                $('header').css({
                    "border-bottom": "solid 1px rgba(255, 255, 255, 0.2)",
                    "padding": "50px 0"
                });
                $('header .member-actions').css({
                    "top": "41px",
                });
                $('header .navicon').css({
                    "top": "48px",
                });
            }
        });
    });

完全删除此功能。

改变

<section class="navigation">

到

<section class="navigation fixed">

如果您想使用其他属性，请将它们添加到 CSS 文件中的以下类中。

header {
  border-bottom: none;
  padding: 35px 0;
}

header .member-actions {
  top: 26px;
}

header .navicon {
  top: 34px;
}
