Do you know what a banner is? It's like a big flag or a sign that you can see from far away. Well, a web banner is like a digital version of that. It's a picture that you see on a website that tries to get your attention and tell you something about a product or a promotion.
Websites use web banners to grab your attention and get you to click on them. Sometimes they even pop up on the screen before you can even see the website! They can come in different shapes and sizes, but they are usually pretty big and bright so you notice them right away.
When you click on a web banner, it can take you to a different website or a special page where you can learn more about what the banner was talking about. For example, if the banner was about a new toy, clicking on it might take you to a page where you can see pictures of the toy and find out where to buy it.
So, web banners are like digital signs that try to get your attention and tell you something cool or new about a product or promotion. They're a way for websites to advertise something and try to get you interested in it.
