How To Enlarge The Lightbox Button

Hi 

I'm using Foster template and I want to make the lightbox form button larger so that it looks the same size as the lower button in the picture provided.

Please can somebody show me the custom CSS to increase the size of that button - Thank you

Can you share your site url?

div#block-yui_3_17_2_1_1572343807229_5513 .sqs-system-button {
    padding: 21px 34px;
    font-size: 15px;
}

21px is padding top/bottom

34px is padding left/right

you can also use: padding: 10px 20px 30px 40px;

(top - right - bottom - left)

@tuanphan - That works brilliant thank you very much
