Use this CSS code in your custom.css or in style.css of a Hueman Child theme:

.home .post-title a:hover { text-decoration: underline; }

Looks like your blog loads all of the posts. Try to limit it to 10 posts per page. Go to the Dashboard -> Settings -> Reading and set Blog pages show at most to 10. Then install WP-PageNavi plugin to have the same navigation as the Hueman demo, instead of “← Older posts | Newer posts →”.

If you want to hide these green comment counts on thumbnails, there are two ways of doing it.
The first way is to turn off Thumbnail Comment Count under WP Admin -> Appearance -> Theme Options -> Blog, but, by doing that, you will also lose the counts on top of the posts.
If you want to preserve those counts in the posts, you can use this CSS code in your custom.css or in the style.css of your Hueman Child theme:

‘.post-comments { display: none; }’

That code will just hide the counts on the thumbnails from showing. It will not disable them.

Thank you, it’s on top now.

It is working now. I have removed the following shortcode from /functions/shortcodes.php file:

/*  Columns / Grid
/* ------------------------------------ */
    function alx_column_shortcode($atts,$content=NULL) {
        extract( shortcode_atts( array(
            'size'  => 'one-third',
            'last'  => false
        ), $atts) );

        $lastclass=$last?' last':'';
        $output='<div class="grid '.strip_tags($size).$lastclass.'">'.do_shortcode($content).'</div>';
        if($last)
            $output.='<div class="clear"></div>';
        return $output;
    }
    add_shortcode('column','alx_column_shortcode');

Finally, I found them using this tutorial: https://beaver6813.com/2012/01/selectors-in-infinite-scroll/ and Google Chrome.

So the CSS selectors are:

Content Selector: #main
Navigation Selector: .more_entries
Next Selector: .more_entries .fl a:first
Item Selector: #main .post

Me too.

OMG, thank you guys! I fixed it.

It was
box-shadow: 0 1px 4px rgba(0, 0, 0, 0.2);
in style.css file. I deleted it.
