Felix(window).on('load', function () {
    Felix('.tabs > label').on('click', function () {
        const children = this.parentElement.children;
        Felix.forEach(children, function (el) {
            if (el.tagName !== 'LABEL') return;
            if (el.className.indexOf('active') === -1) return;
            el.classList.remove('active');
        });
        this.classList.add('active');
    });
});
