Should I create a child theme for a parent custom theme? [closed]

I would definitely avoid using 2 different wordpress themes and instead code for a more responsive website with CSS mediaqueries. It has worked out very well for me on the WordPress websites I created.

If you’re not familiar with media queries, here’s a very basic rundown.

HTML —

<div class="box">hello world</div>

CSS —

.box { width:800px; }

@media only screen and (max-width: 640px) {
  .box { width:450px; }
}
