1. CSS to make it full width:

.single-template-1 .featured-image-wrap {
    width: 100% !important;
    margin: 35px 0 35px 0 !important;
    -webkit-box-shadow:none !important;
    -moz-box-shadow:none !important;
    box-shadow:none !important;
}

2. Not possible with the current code. You can hire someone to do this for you, try http://fiverr.com/

3. In your child theme or theme function.php file at the bottom, add this code:

remove_action( 'ac_single_post_title_info_thumb', 'ac_single_post_thumb' );

function ac_single_post_new_thumb() {
		global $paged;
		$show_thumbnail = get_post_meta( get_the_ID(), 'ac_show_post_thumbnail', true );

			do_action( 'ac_single_post_thumbnail_before' );
			?>
			<figure class="featured-image-wrap">
				<?php
				do_action( 'ac_single_post_thumbnail_before_image' );
				if ( has_post_thumbnail() && $paged == false ) :
					the_post_thumbnail( 'ac-sidebar-featured' );
				else :
					echo '<img src="' . get_template_directory_uri() . '/images/no-thumbnail.png" alt="' . __( 'No Thumbnail', 'justwrite' ) . '" />';
				endif;
				do_action( 'ac_single_post_thumbnail_after_image' );
				?>
			</figure>
			<?php
			do_action( 'ac_single_post_thumbnail_after' );
}
add_action( 'ac_single_post_title_info_thumb', 'ac_single_post_new_thumb', 20 );

// Display text widget
$ac_widget_rp_inst = array( 'title' => 'YOUR TITLE HERE', 'text' => 'YOUR TEXT GOES HERE', 'filter' => true );
echo '<aside class="side-box clearfix widget ac_popular_posts_widget"><div class="sb-content clearfix">';
	the_widget( 'WP_Widget_Text', $ac_widget_rp_inst, $ac_widgets_wrap_args );
echo '</div></aside><!-- END .sidebox .widget -->';

I am sorry but that’s the most I can help you. You should really try and use the provided sidebars. If you need simple customization, like this one, you should try https://www.fiverr.com/, it’s really cheap.

If you find the theme useful and have the time, please leave a review 🙂

Thank you!

It’s not a coding glitch, you just don’t add widgets (with AC SEC in front) in those two sidebars (mentioned above).

Also, I am sorry but this is not a forum for teaching WordPress. You can get started here https://codex.wordpress.org/Main_Page

and ask more general questions here https://wordpress.org/support/

You can’t use widgets prefixed with “AC SEC:” in these sidebars: Main Sidebar & Posts Sidebar. If you want you can use those with “AC:” prefix.

You can find the documentation here: http://www.acosmin.com/documentation/

Recommended image sizes are in JustWrite link.

If you want to change it directly in style.css look for:

.sidebar-heading, .tabs-widget-navigation {

and there should be a font-size: 10px; bellow that. Change 10 to something else.

Your website doesn’t work on my end…
