Hi there,
1) Different buttons are different colours for visual heirachy, and other design reasons. If there are any you’d like to change that you want to be the same, please identify specific buttons and we’ll help with some custom css.
2) You can add this to the custom css panel in theme options:
body, h1, h2, h3, h4, h5, .custom-caption p, span.dropcap1, span.dropcap2, span.dropcap3, span.dropcap4, .spb_call_text, .impact-text, .impact-text-large, .testimonial-text, .header-advert, .sf-count-asset .count-number, #base-promo, .sf-countdown, .sf-icon-character, .fancy-heading h1, strong, .sf-button, h6, .standard-post-date, .sf-count-asset h6.count-subject, .progress-bar-wrap .bar-text > span.progress-value, .portfolio-showcase-wrap ul li .item-info span.item-title, table.sf-table th, .team-member figcaption span, .read-more-button, .pagination-wrap li span.current, #respond .form-submit input#submit, .twitter-link a, .comment-meta .comment-author, .woocommerce span.onsale, .woocommerce .wc-new-badge, .woocommerce .out-of-stock-badge, .woocommerce .free-badge, .woocommerce a.button.alt, .woocommerce .coupon input.apply-coupon, .bag-product-title a, .woocommerce .shipping-calculator-form .update-totals-button button, table.totals_table tr.total {
font-family: "Helvetica Neue", "HelveticaNeue-Light", "Helvetica Neue Light", Helvetica, Arial, "Lucida Grande", sans-serif;
}
Hope that helps!
