Advanced Designer: Change button style of "file upload" button?

Right now the "file upload" button and the submit button at bottom have the same style..I'd like to change this.

I tried using the preset button style options, but nothing other than the border really changed. How can I change the color, font, etc... of ONLY the file upload button?

My form is here: https://form.jotformpro.com/72076115984966

Thanks!

If you only want to style the File Upload button, you can use CSS codes — How-to-Inject-Custom-CSS-Codes

.qq-upload-button {

    font-size: 30px;

    color: yellow !important;

    background: purple !important;

    font-family: "Comic Sans MS", cursive, sans-serif !important;

}

I hope this helps. If you have other questions, please feel free to contact us again anytime.

I have tried this one and it seems to work perfectly in the advanced designer part, but when I go back to "Form Builder", it doesn't show in the form nor in the Designer CSS...

Advanced Design CSS TAB:

Form Builder Design CSS TAB:

I was not able to find the CSS provided by my colleague in the form you have provided.

Have you already applied it? If not yet, please see steps below.
