You've probably seen arrows on a website directing you to keep scrolling down the page after you finish a section. These are simple, super effective styling elements that help out with the flow of your content.

If you've been trying to figure out how to make those elements or you're looking for a way to draw people's attention to other information, follow along with this short tutorial.

It'll take you maybe 5 - 10 minutes to figure out how this works and what it's good for so you aren't wasting any of your time.

You'll only need HTML and CSS to make this element.

The HTML is simple. All you need is a div element with a class name. Here's what that looks like:

```html
<div class="bottom-arrow"></div>
```

That's it for the HTML. Now it's time to look at the CSS which is where you have to get clever.

The style for the **.bottom-arrow** class is easy enough to write.

```css
.bottom-arrow {
	  border-bottom: 5px solid #6A0136;
}
```

The way you make the arrow is where it gets interesting. First you'll start by using the pseudo-class selector, **:after**.

Inside of the selector, you need to set a value for the **content** property. An empty string is fine if you don't have any text you want to show.

Then you have to set a **position** value in order for the arrow to stay on that bottom border you set for the div. Without this value being set, your arrow will not show up where you think it will. Go ahead and see for yourself.

Next you'll want to use the **margin** property to center the arrow on the div. You could also use the margin to give the arrow an offset from the center if that would work better for your design.

After that, go ahead and set the **height** and **width** properties to zero. The reason you want to do this is because if you give the arrow a width, it won't look like an arrow unless you do some crazy CSS magic. The height doesn't necessarily have to be set to zero as long as the width is, but doing so will help you to avoid those nice layout surprises later.

The last thing you have to do is set some border properties. You'll need to set the **border-top** property. This is how you will set the height and color of your arrow.

Next you need to set the **border-left** and **border-right** properties. These control the width of your arrow. An interesting tidbit here is that you don't give the border-left and border-right properties a color. They need to be set to transparent because they are responsible for creating the arrow.

Think of the border-left and border-right properties as cutting a box into a triangle and that's exactly what's happening.

Here's the CSS code that we've been talking about:

```css
.bottom-arrow:after {
    content:'';
    position: absolute;
    left: 0;
    right: 0;
    margin: 0 auto;
    width: 0;
    height: 0;
    border-top: 25px solid #6A0136;
    border-left: 50px solid transparent;
    border-right: 50px solid transparent;
}
```

It's not so bad. You just have to know how CSS works and how it can be manipulated. There are probably 100 other ways of doing this same thing, but this is the way I figured out how to do it.

I hope this quick run through helps!
