我附上了一张屏幕截图,可以更好地解释我想要实现的目标。我无法弄清楚如何删除网站页面导航链接上显示的背景颜色,而不使背景颜色从页面上幻灯片放映的点中消失。我可以添加一些额外的代码来区分两者吗?
这是有问题的代码部分:
.active, .dot:hover {
background-color: #717171;
}
这是我用于幻灯片放映的完整代码:
let slideIndex = 1;
showSlides(slideIndex);
function plusSlides(n) {
showSlides(slideIndex += n);
}
function currentSlide(n) {
showSlides(slideIndex = n);
}
function showSlides(n) {
let i;
let slides = document.getElementsByClassName("mySlides");
let dots = document.getElementsByClassName("dot");
if (n > slides.length) {slideIndex = 1}
if (n < 1) {slideIndex = slides.length}
for (i = 0; i < slides.length; i++) {
slides[i].style.display = "none";
}
for (i = 0; i < dots.length; i++) {
dots[i].className = dots[i].className.replace(" active", "");
}
slides[slideIndex-1].style.display = "block";
dots[slideIndex-1].className += " active";
}

我对如何操作代码的了解有限,因此除了删除有问题的代码行之外,我无法弄清楚它。
定义一个范围来限制规则的影响范围。 “.active”类很常见,因此可能会与网站上的其他元素发生冲突。
例如:
.slideshow-container .dot.active, .slideshow-container .dot:hover {
background-color: #717171;
}
