Hello Candice

That is a group of four icons.

You can style it by modifying one of the styles:

.thumb-icon {

     border: 2px solid #000;

    box-sizing: border-box;

    float: left;

    height: 9px;

   margin: 1px;

   opacity: 1;

   transition: opacity 0.2s ease-in-out 0s;

   width: 9px;

}

and then add the custom styles in theme options -> styling options -> custom css

Or you can open /sections/header_button_section.php file (path relative to root theme folder)

and modify

<a class="show-thumbnails animation-link" href="<?php echo esc_url( $california_showcase_url ); ?>">
<div class="thumb-icon"></div>
        <div class="thumb-icon"></div>
        <div class="thumb-icon"></div>
        <div class="thumb-icon"></div>                
    </a>

lines 41-46

Let us know if you have any other questions

Hello Candice,

yes that icon is mean to go to a full showcase page, an entire portfolio page or any other link you may consider.

To change the url you should in the carousel or showcase page options (Add/Edit page), press 'Showcase Templates' tab and change 'Showcase URL' field

If you don't need ti you can hide it with 

a.show-thumbnails {

display: none;

}
