The slider is used to select the number of words that can be seen at once. So a user can increase it to say 10 and now every 1 second, a set of 10 words need to...

To better explain, think of how CSS works to style HTML. You can hierarchically target controls with CSS via selectors: div > span em { color: blue; } ul.class > li ul li { displa...
