将幻灯片指示器更改为其他形状

Question

很抱歉中途更改问题，但我还想问更多。

我目前正在使用幻灯片指示器的默认形状，这是一个点/项目符号形状的指示器。

问题：

• 有没有办法把它改成其他形状，比如矩形？

由于时间限制，我没有太多时间从头开始制作幻灯片，所以我只是主要从 W3School 站点获取此代码并按原样使用它。

这是HTML代码的一部分：

<div class="slideshow-container">
<h1 class="page_title">IR</h1>
<div class="mySlides fade">
<a href="/ir/library/results_briefing/"></a>
<img src="/ir/images/slider_img02.jpg" alt="A" style="width:100%">
<div class="text">A</div>
</div>
<div class="mySlides fade">
<a href="/ir/investment/event/"></a>
<img src="/ir/images/slider_img01.jpg" alt="A" style="width:100%">
<div class="text">A</div>
</div>
<div class="mySlides fade">
<a href="/ir/library/"></a>
<img src="/ir/images/slider_img03.jpg" alt="IRA" style="width:100%">
<div class="text">IRA</div>
</div>
<div class="mySlides fade">
<a href="/ir/business/message/"></a>
<img src="/ir/images/slider_img04.jpg" alt="A" style="width:100%">
<div class="text">A</div>
</div>
<div class="mySlides fade">
<a href="/ir/calendar/"></a>
<img src="/ir/images/slider_img05.jpg" alt="A" style="width:100%">
<div class="text">A</div>
</div>
<a class="prev" onclick="plusSlides(-1)">&#10094;</a>
<a class="next" onclick="plusSlides(1)">&#10095;</a>
</div>
<br>
<div style="text-align:center">
<span class="dot" onclick="currentSlide(1)"></span>
<span class="dot" onclick="currentSlide(2)"></span>
<span class="dot" onclick="currentSlide(3)"></span>
<span class="dot" onclick="currentSlide(4)"></span>
<span class="dot" onclick="currentSlide(5)"></span>
</div>

这是 JavaScript

<script>
var slideIndex = 1;
var timer = null;
showSlides(slideIndex);
function plusSlides(n) {
clearTimeout(timer);
showSlides(slideIndex += n);
}
function currentSlide(n) {
clearTimeout(timer);
showSlides(slideIndex = n);
}
function showSlides(n) {
var i;
var slides = document.getElementsByClassName("mySlides");
var dots = document.getElementsByClassName("dot");
if (n==undefined){n = ++slideIndex}
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";
timer = setTimeout(showSlides, 4000);
}
</script>

和 CSS ：

* {box-sizing: border-box}
<meta name="viewport" content="width=device-width, initial-scale=1.0">
body {font-family: Verdana, sans-serif; margin:0}
.mySlides {display: none}
img {vertical-align: middle;}
/* Slideshow container */
.slideshow-container {
max-width: 1000px;
position: relative;
margin: auto;
}
/* Next & previous buttons */
.prev, .next {
cursor: pointer;
position: absolute;
top: 50%;
width: auto;
padding: 16px;
margin-top: -22px;
color: black;
font-weight: bold;
font-size: 18px;
transition: 0.6s ease;
border-radius: 0 3px 3px 0;
}
/* Position the "next button" to the right */
.next {
right: 0;
border-radius: 3px 0 0 3px;
}

/* Caption text */
.text {
background-color: #424242;
color: #ffffff;
opacity: 0.8;
font-size: 15px;
padding: 8px 12px;
position: absolute;
bottom: 0px;
width: 100%;
text-align: center;
}
/* Number text (1/3 etc) */
.numbertext {
color: #f2f2f2;
font-size: 12px;
padding: 8px 12px;
position: absolute;
top: 0;
}
/* The dots/bullets/indicators */
.dot {
cursor: pointer;
height: 15px;
width: 15px;
margin: 0 2px;
background-color: #bbb;
border-radius: 50%;
display: inline-block;
transition: background-color 0.6s ease;
}
.active, .dot:hover {
background-color: #717171;
}
/* Fading animation */
.fade {
-webkit-animation-name: fade;
-webkit-animation-duration: 1.5s;
animation-name: fade;
animation-duration: 1.5s;
}
@-webkit-keyframes fade {
from {opacity: .1}
to {opacity: 1}
}
@keyframes fade {
from {opacity: .1}
to {opacity: 1}
}
/* On smaller screens, decrease text size */
@media only screen and (max-width: 300px) {
.prev, .next,.text {font-size: 11px}
}

Answer 1

如果你在CSS中稍微改变一下，你可以这样做。试试这段代码。

.dot {
cursor: pointer;
height: 10px;
width: 30px;
margin: 0 2px;
background-color: #bbb;
display: inline-block;
transition: background-color 0.6s ease;
}

这是在悬停时删除箭头中的下划线，

.prev:hover,
.next:hover {
text-decoration: none;
}

Answer 2

请使用此代码

var slideIndex = 1;
var timer = null;
showSlides(slideIndex);
function plusSlides(n) {
clearTimeout(timer);
showSlides(slideIndex += n);
}
function currentSlide(n) {
clearTimeout(timer);
showSlides(slideIndex = n);
}
function showSlides(n) {
var i;
var slides = document.getElementsByClassName("mySlides");
var dots = document.getElementsByClassName("dot");
if (n==undefined){n = ++slideIndex}
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";
timer = setTimeout(showSlides, 4000);
}

/* Next & previous buttons */
.prev, .next {

}
/* Position the "next button" to the right */
.next {
right: 0;
border-radius: 3px 0 0 3px;
}
/* Caption text */
.text {

}
/* Number text (1/3 etc) */
.numbertext {
color: #f2f2f2;
font-size: 12px;
padding: 8px 12px;
position: absolute;
top: 0;
}
/* The dots/bullets/indicators */
.dot {

animation-duration: 1.5s;
}
@-webkit-keyframes fade {
from {opacity: .1}
to {opacity: 1}
}
@keyframes fade {
from {opacity: .1}
to {opacity: 1}
}
/* On smaller screens, decrease text size */
@media only screen and (max-width: 300px) {
.prev, .next,.text {font-size: 11px}
}
.dot {
cursor: pointer;
