How can I form hyperlink text in a form?

Site URL: https://www.joinwavelength.com/affiliate-signup

I have a hyperlink in this form (it's the text that says "Download the app here." I'm accomplishing this by typing in the following text:

Quote

<a href="https://wavelength.onelink.me/fpLC/26ab95e2" target="_blank">Download the app here.</a>

Is there a way to change just the text color for this hyperlink. I want the other description text to remain the same, so I can't just change the theme's font colors. I want to make this hyperlink blue so it's more obviously a hyperlink.

Add to Home > Design > Custom CSS

div.description a {
    color: blue;
    text-decoration: underline;
}
