Cant acces to .css to customize virtuemart

[Roccofx1]

Hi

Im new to joomla and Virtuemart 3, i want to improve the product page, i must acces to the .css file of virtuemart, i have search in here the way to do so and found a common answer, but the problem is that i cant acces to it by doing it and writig:

http://mydomain/components/com_virtuemart/virtuemart.php

A message says:

Direct Access to virtuemart.php is not allowed

Also if i write:

http://mydomain/templates/mytemplatename/html/com_virtuemart/

A message says:

You don't have permission to access /templates/mytemplatename/html/com_virtuemart/ on this server.

A) Why is that happening and what can i do?

b) Also i want to create an override, because i dont want to make changes that will be changed after virtuemart updates, how can i do it?

Why Virtuemart has so many options but so little to edit the product page design? is there a plugin for that, aniway i will try by the .css

Thanks, please help

Hard to know where to start.

here is the info you need... ->  http://docs.virtuemart.net/tutorials/templating-layouts.html

But with your knowledge of how a website works, css and html I think this will be of no use to you...

I think you should start by Googling some basic html/css and website tutorials and understand how a website is constructed and styled...

I agree, difficult to know where to start learning all this stuff.
Maybe better to learn about Joomla first, https://docs.joomla.org/Portal:Beginners/Absolute_Beginners_Guide

You cannot use a browser to access files for editing. If you are on a remote host then use ftp to download files for editing. If on localhost (which is probably the easiest & cheapest way to learn) then you can access the files using Win file manager and open them for editing.
