The CSS framework slideshow is a simple slider.
There are many more extensive sliders on the internet, free or paid, but the disadvantage of this is often the complicated code and memory consumption.
I like to assume that the simple approach often yields pretty good things. You can of course discuss this ...
<div style="display: inline-block;">
<span class="content">Slide one</span>
<span class="content">Slide two</span>
