TOPIC: Customize Details Button

Is there a way to create "Details" buttons instead of using an image? If so, how do we go about doing that?

You can create your own button, yes, but you need to give it the EXACT same file name as the existing image. The images are in:

/components/com_dtregister/assets/images/

Then pick the color folder that you are using. You'll see all of your images there that can be replaced.

I meant create it in css.

No, the button is not controlled by CSS. The actual text is part of the image.
