faq block

hi i am trying to figure out how to add the cursor to the accordion as well as changing the link color on some of the tabs. for some reason it keeps flagging it. if you guys can take a look and let me know what is wrong?

.schema-faq.wp-block-yoast-faq-block {
    padding: 0 30px;
    border: 1px solid #f4f4f4;
    background-color: #1fc8db;
    background-image: radial-gradient( circle,rgb(66, 181, 199) 0%, rgb(25, 22, 84) 100%);
    color: #fff;
  
}
strong.schema-faq-question {
    cursor: pointer;
    padding: 20px 0;
    border-bottom: 1px solid #f4f4f4;
    position: relative;
    display: block;
    color: #fff;
    font-size: 16px;
    font-family: 'Roboto Slab', serif;
    font-weight: 700;
}
p.schema-faq-answer {
    color: #000;
    background: #f7f7f7;
    display: none;
    padding: 20px 20px;
    link: blue;

}
strong.schema-faq-question:before {
    font-size: 24px;
    font-weight: 500;
    transition: all 0.3s ease 0s;
    top: 0;
    left: 0;
    width: 100%;
    color: #fff;
    content: "\f055";
    font-family: 'FontAwesome';
    margin-right: 20px;
}
strong.schema-faq-question.active:before {
    content: "\f056";
