Creating a custom single advert page

Hi,
the best way to create a custom view for the Ad details page is to add in your theme folder a file named single-advert.php and copy to it content from page.php or single.php and customize, more details about it you will find here https://wpadverts.com/documentation/child-themes-and-templates/ in “Custom Post Type Template” section.

You can move the images to the right with CSS or create a child-template file for the wpadverts/templates/single.php file and the customize the HTML to your needs (also explained in the article linked above).

Regarding changing the image sizes please see https://wpadverts.com/documentation/custom-image-sizes/

One note about CSS changes, it is best to overwrite the default CSS rules by adding new rules in wp-admin / Appearance / Customize / Additional CSS panel, the changes you do in adverts-frontend.css file will be overwritten on each WPAdverts update.

Perfect, thanks that worked really well. The only issue I found is that overwriting the CSS rules doesn’t seem to work. For example I’ve added these rules:

.wpadverts-slide img {
height: 750px;
}

.wpadverts-slide-img{
height:750px;
}

in the ‘Additional CSS’ customizer and they don’t affect anything. Editing the wpadverts-frontend.css obviously works but I realise it’s not ideal. Is there anything that I might need to do to get the additional rules to take effect?

The two rules you created will be basically ignored as the rules in adverts-frontend.css take precedence, try postfixing all the values with !important keyword like this

.wpadverts-slide img {
   height: 750px !important;
}
.wpadverts-slide-img{
    height:750px !important;
}
