[英]Why my font color in navbar didn't change when i toggle to sticky?
我對 css 還是新手,並嘗試制作一個帶有白色和黑色字體背景的粘性導航欄。 我正在努力尋找解決方案,但無法弄清楚出了什么問題。
這是我的初始導航欄看起來像初始導航欄
And here's scrolled navbar Scrolled Navbar圖片不清楚,但字體仍然是白色的,帶有一點黑色輪廓,即使我將字體顏色更改為黑色
這是我的 HTML 代碼:
<header id='navbar'>
<a href="#" class="brand">LOGO</a>
<div class="menu">
<div class="btn">
<i class="fas fa-times close-btn"></i>
</div>
<a href="#">Jadi Partner</a>
<a href="#">Lapangan Favorit</a>
<a href="#">Pesanan Saya</a>
<div class="dropdown">
<button class="dropbtn">
<i class="fas fa-bars" id="menu-dropdown"></i><i class="fas fa-user-circle"></i>
</button>
<div class="dropdown-content">
<a href="#">Log In</a>
<a href="#">Sign Up</a>
</div>
</div>
</div>
<div class="btn">
<i class="fas fa-bars menu-btn"></i>
</div>
</header>
<script type="text/javascript">
window.addEventListener('scroll', function () {
// var header = document.querySelector('header');
var header = document.querySelector('header');
header.classList.toggle('sticky', window.scrollY > 0);
})
</script>
<script type="text/javascript">
//Javacript of responsive navigation menu
const menuBtn = document.querySelector(".menu-btn");
const navigation = document.querySelector(".navigation");
menuBtn.addEventListener("click", () => {
menuBtn.classList.toggle("active");
navigation.classList.toggle("active");
});
</script>
這是 CSS 部分:

這部分已編輯我發現只有導航欄它工作得很好,但是當我在導航欄下方添加背景圖像時出現問題。 這是導航欄下方的背景代碼:
<section class="home">
<div class="images-home">
<img src="{% static 'main/images/basketball.jfif' %}" alt="" class="image-slide">
<img src="{% static 'main/images/prapoth-panchuea-OMWubltUEfE-unsplash.jpg' %}" alt="" class="image-slide">
<img src="{% static 'main/images/muktasim-azlan-rjWfNR_AC5g-unsplash.jpg' %}" alt="" class="image-slide">
</div>
<div class="content">
<h1>Train. Grow. Repeat.<br></h1>
<p>Lorem ipsum dolor, sit amet consectetur adipisicing elit. Maiores magnam quia vitae, animi unde consequuntur

<div class="slider-navigation">

我讀了一些關於,重要的。 但這無濟於事:感謝任何願意幫助像我這樣的業余愛好者的人:)
您需要將background-color
和color
屬性添加到 header 選擇器而不是header.sticky
。
由於您正在動態添加粘性 class,因此首先渲染 colors 實際上並不可見。
更新
檢查了您的代碼筆,您錯過了 when.sticky class 通過 JS 應用的屬性
header.sticky .dropdown .dropbtn {
background-color: #000;
}
header.sticky .brand{
color: #000;
}
