CSS code that can be used to style a download button

 Here's an example of CSS code that can be used to style a download button:

```

.download-button {

  background-color: #007bff; /* Set the background color */

  border: none; /* Remove the border */

  color: #fff; /* Set the text color to white */

  padding: 10px 20px; /* Add padding to the button */

  text-align: center; /* Center the text */

  text-decoration: none; /* Remove the underline */

  display: inline-block; /* Make the button a block element */

  font-size: 16px; /* Set the font size */

  cursor: pointer; /* Change the cursor to a pointer */

}

.download-button:hover {

  background-color: #0062cc; /* Change the background color on hover */

}

```

To use this code, simply add the `download-button` class to your button element. For example:

```

<a href="path/to/download/file" class="download-button">Download</a>

``` 

Note that you'll need to adjust the styles to match the design of your website.
