My question is, that why doesnt the align-items-center class work? It does nothing, the text is at the top of the div.
The row div alredy have flex display, because i am using bootstrap 4.
How can i align it center vertically?
<section class="aloldal_section_bg w-100">
<div class="container">
<div class="row align-items-center">
<div class="col-sm-12">
<h1 class="page_title"><?php echo $pageTitle; ?></h1>
</div>
</div>
</div>
