Unwanted white space when I go into mobile view - html

Question

Does someone know how to remove this white space?
This only occurs when I'm in mobile view.
Image of the problem. Untitled:
I tried using responsive instead of fluid but that doesn't solve the problem completely, the image is just scaled up.
HTML code of these boxes
<div class="row no-gutters">
<div class="col-6 d-flex align-items-center flex-column justify-content-center bg-dark">
<h2 class="mb-0 text-white">Za miran život bez stresa!</h2>
<br>
<p class="mb-0 text-white-50">321 GARAŽNO MESTO</p>
<p class="mb-0 text-white-50">+ priključci za električni automobil, auto-perionica u garaži.</p>

replace your class img-fluid for w-100 h-100 and object-fit: cover in css
img {
object-fit: cover
}
