Footer Transparency & Underlined Links

Site URL: https://www.ralphrodriguez.work

Hello, was wondering if it was possible to get the footer of my website to be transparent? Also, in my portfolio section of the homepage, how do I remove the underline on the links and change link color on hover? My website is www.ralphrodriguez.work. Thanks in advance!

Add to Home > Design > Custom CSS

footer.sections .section-background {
    background-color: transparent !important;
}
/* remove underline */
span.portfolio-hover-item-content {
    text-decoration: none !important;
}
span.portfolio-hover-item-content:hover {
    color: red;
}
