As I would like to update the current theme, I am looking for the source code location I am able to modify to change the layout from the login page.
What I have understand right now, is the config.php in my theme folder(aardvark) apply the CSS style for all the pages.
However, from login/index.php, login/signup.php and login/signup_form.php, I found the forms were constructed by mform(moodleform), which was built in lib/formslib.php
What I would like to achieve is to customize the label length, color and form background color in login and signup page, could anyone help me with that? Thanks
