要使用CSS和JavaScript创建报价幻灯片，代码如下-
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1" />
<style>
body {
font-family: "Segoe UI", Tahoma, Geneva, Verdana, sans-serif;
}
h1 {
text-align: center;
}
* {
box-sizing: border-box;
}
.Slide {
display: none;
}
img {
vertical-align: middle;
width: 100%;
height: 400px;
}
.slideContainer {
max-width: 600px;
margin: 10px;
position: relative;
margin: auto;
}
.prevBtn, .nextBtn {
position: absolute;
top: 50%;
width: auto;
padding: 10px;
background-color: rgb(255, 255, 75);
color: rgb(50, 0, 116);
font-weight: bolder;
font-size: 18px;
}
.nextBtn {
right: -40px;
}
.prevBtn {
left: -40px;
}
.Caption {
color: #500070;
font-weight: bold;
font-family: "Segoe UI", Tahoma, Geneva, Verdana, sans-serif;
font-size: 25px;
padding: 8px 12px;
position: absolute;
width: 100%;
text-align: center;
}
.Navdot {
cursor: pointer;
height: 15px;
width: 15px;
margin: 0 2px;
background-color: rgb(54, 5, 117);
border-radius: 50%;
display: inline-block;
transition: background-color 0.6s ease;
display: inline-block;
margin-top: 30px;
}
.selected, .Navdot:hover {
background-color: #d9ff00;
}
@media only screen and (max-width: 450px) {
.prevBtn, .nextBtn, .Caption {
font-size: 16px;
}
}
</style>
</head>
<body>

var slideIndex = 1;

Array.from(dots).forEach(

);
slides[slideIndex - 1].style.display = "block";
