Question: hi all I think I'm asking quite a basic question still iI'm having some problems:
i'm working with .htaccess

and from 
<http://v1.piattisti.it/v2/v3>  

I would like to Get 

```
$_GET['v1'] 
$_GET['v2'] 
$_GET['v3']

```

at least to solve the first problem i tried

```
RewriteEngine On
Options -Indexes
RewriteCond %{HTTP_HOST} !^www\.
RewriteCond %{REQUEST_URI} !index\.php
RewriteCond %{HTTP_HOST} ^(.+?)\.piattisti\.it$
RewriteRule .* /index.php?v1=%1 [L]

```

but is not working...
thanks for the support

Answer: 
I don't think it's a problem. Bootstrap isn't really there to restrict you to their styles but give you a starting point. If people didn't overwrite their styles many Bootstrap site would end up looking exactly the same.

That being said there are certain overrides that you have there that could be configured in the variables such as `border`, `border-radius`, `margin`, etc.

*Edit:* Forgot you mentioned Bootstrap 4. What I posted was for 3.

Bootstrap 4
-----------

You override variables in your own theme. <https://getbootstrap.com/docs/4.0/getting-started/theming/#variable-defaults>

The variables you want to override are:
<https://github.com/twbs/bootstrap/blob/master/scss/_variables.scss#L447>

Bootstrap 3
-----------

<https://getbootstrap.com/docs/3.4/customize/#forms>
It is a bad practice is you are using things over and over again or if someone else is going to edit of make things

You can better add another class with a proper understandable name and style that one.

And never edit the Bootstrap files directly user your own css file.
