A news ticker is a single line of text that scrolls continuously across the screen. It typically shows current news items, sporting results, live financial and currency information, and weather information.
This is similar to how you might use a sticky floating footer bar.
Tickers are a great way to display small snippets of information in an eye-catching way. Since the content is always scrolling, you can also use tickers to show lots of information in a limited space on your WordPress blog.
For example, you might use a news ticker to display your best-performing posts, announce an upcoming sale, or share other useful information.
