Reply To: Slider and Slider Wide Margin

The home-feature-4 and 5 space is actually coming from the classes – .home-feature-bg-alt .wrap and .home-feature-dark.wrap They are repeated for all of the widget areas home-feature 1 -14 to save space. You could add and replace the ones inside your home.php file with your own classes (which will have less space once you style it)

For the space in the header (when responsive mode kicks in) this is the code that it’s using (line 1980) –

.header-image .site-header .widget-area {
    padding: 40px 0;
    padding: 2.5rem 0;
}

So you could copy that and add it to your Responsive sections and reduce the padding so it will remove the space in mobile view.
