You can remove the background from the text on your Dawn theme's image banner through the theme editor. You can follow the steps below to do this.
I'm glad you're giving close attention to the small details on your homepage. Your homepage design is important as it's the main landing page for most website visitors. It introduces your brand to potential customers so it's crucial to set it up in a way that would improve the user experience in your website. Removing the text box background is a great way of doing this as it properly exhibits the full image and the products on your banner.
Another page that's as important as the homepage is your collection page. Collection pages showcase your products, and how they do this can affect the behavior of your website visitors. It can either push them to check out your products or leave your website. If you want to optimize and improve your collection pages, you can do so by resizing your product images and making them consistent. That can give a more polished and professional look, resulting in a better virtual experience for visitors and customers. You can use the app, Photo Resize, to easily resize your images.
