[Rails] I think I've found a mistake in Rails tutorial

app/views/shared/_error_messages.html.erb
app/assets/stylesheets/custom.css.scss

I made all the modifications (until I saw the working image to the 4 files), and I still get the error image above when submitting the file, rather than a page that shows me that I left the fields blank.

Can you help with this?

There is no params as I am just clicking a Signup button that's on a page,
then the error shows up.
I'm using Ruby 1.9.3 and the latest versions of sass-rails and
coffee-rails.

development.log says this

To add since I neglected to mention it like I should have, just
because your form is blank does not mean there are no params, blank or
not it will create a param as the form still sends the fields, that is
why you see them listed there with "". "" is not a null value, it is
an empty value, empty != null, nil == null because even a blank value
is a value to all systems. This is why Rails has .blank? and
.present? so you can work around this situation, but tbh you should
not need to as after you permit them and then pass them into the model
it should have already done a validator stating that you do not wish
it to be blank or null.
