How do I access the css and php files to customize the Registration Form? I would like to change the alignment of checkbox options. They don't look right. Also, I would like to be able to enhance the text, when desired, to make some fields pop out more than others, as well as sometimes change the fonts around.
The main CSS file for DT Register is here:
/components/com_dtregister/assets/css/main.css
However if you want to apply styling to just selected field labels, you can add the styling directly in the field label in the setup.
Also, checkbox and radio button fields have a parameter "New Lines" that you can use to make the options line up vertically (in new lines) or build horizontally.
