The showcase section is formed by:

<section id="g-showcase">

    <div class="g-container">

        <div class="g-grid">                        

            <div class="g-block size-50"></div>

            <div class="g-block size-50"></div>

        </div>

</section>

I have two

<div class="g-block size-50"></div>

cause thoese are showcase-a and showcase-b, inside them i have some text. So, i would like to know how can i add the class uk-grid-match at

<div class="g-grid">

cause i want both have same height.

Have some file that i can change this or just by jQuery to insert this another class?
