Theme development

I would like some help to style a Ctools modal pop-up. I have added a theme and views template but it has no effect so it looks as though I am missing some fundamental point.

Here is a picture of the default style and the styled box, as per the article above.

You can see the pop-up in its current state here. Just click the link on the single Views record.

I'm using better exposed filters in my view with a Gmap format. Each exposed filter has the exact same class name associated with it. Usually "panel-heading." I thought I could manipulate this heading with some custom CSS however I've come to find out that there are other instances of panel-heading across the website. So the panel-heading class is being generated.

Hello!

How i can to add own global vars for using in twig templates?
I don't know how to use this example snippets:

$path = 'path/to/templates';
$loader = new \Twig_Loader_Filesystem($path);
$twig = new \Twig_Environment($loader);
$twig->addGlobal('my_var_name', 'my value');

or

I want to have my logo on the left of the header section and the main navigation to the right. I am using the Foundation 6 framework with its associated grid. www.debitsandcredits.com

I have determined that I need to create a header_left and a header_right in place of the full header section. I was able to create those regions in my info.yml file.

Where I am confused is where do I change the header to header_left and then add a div for the header_right in the page.html.twig. Here is the relevant section.

How to check if an article tag has certain value in twig template?

Hi,

i'm trying to create a login-page that doesn't use the default theme.
I created a second theme that i enable trough the 'page theme' module to show the user/login page.
while customizing this page i used the page.tpl.php, not a template.

The login form does work however if i use the default theme with a template page user-login.tpl.php.
But this is not what i want, because it calls up the header, footer, etc... of the default theme.
