Looking to insert horizontal lines within slides. I'm new to design and would appreciate some help with the code for adding interior lines in the sliders. Can anyone provide assistance with this?
<div class="slideshow-container">
<div class="mySlides fade">
<div class="numbertext">1 / 3</div>
<img src="banner.jpg" style="width:100%">
<hr>
<div class="text">Caption Text</div>
</div>
<div class="mySlides fade">
<div class="numbertext">2 / 3</div>
<img src="banner.jpg" style="width:100%">
<hr>
<div class="text">Caption Two</div>
</div>
<div class="mySlides fade">
<div class="numbertext">3 / 3</div>
<img src="banner.jpg" style="width:100%">
<hr>
<div class="text">Caption Three</div>
</div>
<a class="prev" onclick="plusSlides(-1)">❮</a>
<a class="next" onclick="plusSlides(1)">❯</a>
</div>
<br>
<div class="center">
<span class="slide" onclick="currentSlide(1)"> 01.</span>
<span class="slide" onclick="currentSlide(2)">02.</span>
<span class="slide" onclick="currentSlide(3)">03.</span>
</div>
