Number of Fetured Content cannot be reduced

@lbc: Thank you for using Adventurous theme.
I checked your site and the issue is because of the Custom CSS you are using. Below is the Custom CSS you are using and I’ve commented out the code that is causing the problem please check.

#masthead #site-logo img {
    max-height: 80px; /* Your desired height for normal header logo */
}

#masthead.fixed-header #site-logo img {
    max-height: 45px; /* Your desired height for fixed header logo */
}

/*.container {
    width: 98%;
    padding: 0 10px;
}*/

#featured-heading{
    width: 100%;
}
/*#featured-post.layout-four .featued-content-wrap, #featured-post.layout-three .featued-content-wrap {
    width: 100%;
}

#featured-post.layout-four .post, #featured-post.layout-three .post {
    width: 23%;
}*/

@media screen and (min-width: 981px) {

    #secondary .widget {
        width: auto;

    #featured-post .featued-content-wrap {

#powered {
      display: none;
}

Note: You can either copy the above CSS or remove the commented out codes and use the remaining.
