Custom CCS Font changing on safari

Please check again Custom CSS. The font face code is incorrect.

Your code

@font-face {
    font-family: 'nevis';
    src: url 'https://static1.squarespace.com/static/6010809e7aec136e0f8e596f/t/6012929cac62e54e76997908/1611829916661/nevis.ttf';
    font-weight: regular
}

It should be

@font-face {
    font-family: 'nevis';
    src: url('https://static1.squarespace.com/static/6010809e7aec136e0f8e596f/t/6012929cac62e54e76997908/1611829916661/nevis.ttf');
    font-weight: regular;
}

Do similar for other font face code

THANK YOU!
