HD Quiz - Feature image below question ( costom css)

One of your requests at least can be easily done by adding some custom CSS to your site.

Feature image below question

If you want to reverse the order of the question title and the feature image, adding the following CSS to your site will do the trick.

.hdq_question {
	display: grid;
	grid-template-areas: "question_title" "featured_image";
}
.hdq_question_featured_image {
	grid-area: featured_image;
}
.hdq_question_heading {
	grid-area: question_title;
}

You can either add that code to your theme’s style.css file, or use the theme customizer to add it (log into your admin area, then go to appearance -> customize -> additional CSS)
