How will I use :: after to make an arrow on my button?

Question

I can create an arrow button on the right side like this:

.next-button {
    font-family: 'Source Sans Pro', Arial, Helvetica, sans-serif;
    text-decoration: none;
    color: #fff;
    text-align: center;
    border: none;
    background-color: #2399e5;
    display: inline-block;
    height: 36px;
    line-height: 36px;
    padding: 0 1rem;
}

.next-point{
    vertical-align: top;
    width: 0;
    height: 0;
    display: inline-block;
    border-top: 18px solid transparent;
    border-bottom: 18px solid transparent;
    
    border-left: 18px solid #2399e5;
    border-right: 18px solid transparent;
}

<div>
<button class="next-button" type="button">Next</button><div class="next-point"></div>
</div>

Run code

... but if I try to do this using :: after it just doesn't work. Here is how I tried this:

.next-button {
    font-family: 'Source Sans Pro', Arial, Helvetica, sans-serif;
    text-decoration: none;
    color: #fff;
    text-align: center;
    border: none;
    background-color: #2399e5;
    display: inline-block;
    height: 36px;
    line-height: 36px;
    padding: 0 1rem;
}

.next-button::after{
    content: " ";
    vertical-align: top;
    width: 0;
    height: 0;
    display: inline-block;
    border-top: 18px solid transparent;
    border-bottom: 18px solid transparent;
    
    border-left: 18px solid #2399e5;
    border-right: 18px solid transparent;
}

<div>
<button class="next-button" type="button">Next</button>
</div>

Run code

I have been doing this for a long time, and I clearly don’t understand how to use it ::after. How would I search for a button in my first snippet using ::afterinstead of creating a separate div?
