bump? Anyone?

[Generate two buttons div]

Hello, 

First post, very not expert.

 

I have this page I'm editing (from a wordpress theme called "lay theme"): http://mtthsstffn.altervista.org/tagnacht/

 

In this carousel that scrolls images, I need to move the "next" "prev" clickable area slightly outside the images. I think I want to make two invisible divs, left and right, that overlay the image and occupy the center-to-left and center-to-right area of the carousel, with a variable length I can define.

 

A friend suggested to add this 

<div id="nav-left" style="
    height: 800px;
    display: block;
    width: 50%;
    position: absolute;
    top: 0;
    ;
    pointer-events: left;
    cursor: move;
"></div>

inside <div class="lay-carousel-wrap immediate">

 

I think it can be right, but where can I find the files I need to do it? 

I looked around the whole website and couldn't find the HTML with this element, hence I think it's automatically generated with PHP, but I have no idea where to start for this.
Thanks for any help!
