Pulling specific terms in wordpress template

Pulling specific terms in wordpress template

I am trying to create a two different portfolios on a Wordpress site by
creating two templates, as I need each portfolio to have a different
background color and logo. I am attempting to edit the current filterable
portfolio template. I can see the it is pulling in the term 'skill', which
I label each project with (i.e. ads, logos, etc.) and would like to limit
which skills it pulls in. One portfolio will be a design portfolio pulling
in the skills ads, logos, collateral, pro bono, and the second portfolio
will pull in another set of specific skills. Could someone please help me
with how to pull in specific skills? I have included the current
filterable portfolio code. Thank you in advance.
<?php
/**
* Template Name: Portfolio - Filterable
* Description: Template to display filterable portfolio items
*/
get_header();
$portfolio_title = stag_get_option( 'portfolio_title' );
$portfolio_subtitle = stag_get_option( 'portfolio_subtitle' );
?>
<div id="primary" class="content-area">
<main id="main" class="site-main" role="main">
<header class="page-header page-header--portfolio">
<?php if( ! empty( $portfolio_title ) ) echo "<h1
class='blog-title'><span>{$portfolio_title}</span></h1>"; ?>
<?php if( ! empty( $portfolio_subtitle ) ) echo "<p
class='blog-subtitle'>{$portfolio_subtitle}</p>"; ?>
</header>
<ul class="portfolio-filter">
<li class="button filter" data-filter="all"><?php _e('All',
'stag'); ?></li>
<?php
$terms = get_terms('skill');
$count = count($terms);
$i = 0;
if($count > 0){
foreach($terms as $term){
echo "<li class='button filter'
data-filter='{$term->slug}'>{$term->name}</li>";
}
}
?>
</ul>
<section id="portfolio-filter" class="grids portfolio-items">

while( $the_query->have_posts() ): $the_query->the_post();
