我尝试使用此行代码使幻灯片显示响应式
<img src="nature.jpg" alt="Nature" class="responsive">
.responsive {
width: 100%;
height: auto;
}
但是这没有任何区别。我在这里上传了我的网站：https://acaschoolgpa.000webhostapp.com/

<h2 class="message">Our Message</h2>
<p id="messagetext" align="justify">"Long before National Honor Society was available in the American Creativity Academy, students sought after an opportunity to create, inspire, and open the doors for creativity. With a heritage of respect to individuality and personal interest, the National Honor Society offered a platform for creation and student ingenuity. Today, the dream of a boy who grew up between the blue walls of ACA turned into reality: he can finally create and enjoy creation for a respected audience!</p>
<p id="messagetext" align="justify">The National Honor Society is a community by students within the campus that works towards creating a better school and local environment. We believe that every act of kindness, no matter how insignificant it may seem, has a drastic impact on a person and starts a ripple of kind-hearted acts among the people. The NHS creates opportunities for its members in volunteering within and off the campus and raising awareness for global issues, which makes them more productive, responsible and engaged citizens. We try to make a difference by inspiring and supporting the people around us whenever we can.</p>
<p id="messagetext" align="justify">The NHS team is more than all of its members; although the impact of one person is limited, working as a team allows us to achieve our goal and leave behind a great mark. We envision a kinder society where people are keen on helping others, and will work until that vision is achieved."</p>

}
function currentSlide(n) {
showSlides(slideIndex = n);
}
function showSlides(n) {
var i;
var slides = document.getElementsByClassName("mySlides");
var 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";

}
setInterval(function() {

我的网站在移动设备上看起来确实很奇怪，但在PC上看起来很棒。主要是因为幻灯片
答案 0 :(得分：0)
首先删除最小宽度：1000px；在您的幻灯片容器中。如果您需要网站具有响应能力，则绝对不要将最小宽度指定为大于400像素。 其次，请始终调整您的容器而不是图像的宽度或高度。尽量不要超过图像的高度，因为它看起来像是拉长的。尝试使用背景大小：100％100％；显示整个图像。
.slideshow-container {
min-width: unset;
min-height: 400px;
}
.mySlides {
height: 100%;
min-height: 400px;
max-width: 100%;
}
第三，不要在单个元素上两次指定类属性。使用相同的属性，并在其中添加多个类。 class =“ slideshow-container响应式”
