Theme development

I know this is likely a question so basic that most people will be laughing, perhaps even chortling.  But I come from a non-CMS background where to increase a font, say, or choose a different font-family, one simply navigates to the whatever.css file and finds the right line and changes it.  It's usually quite easy to read, too.

I am kind of blown away at the difficulty of doing something as simple as identifying the title of my Bartik page and changing its color.

I want to insert in bootstrap theme some js effects, I did everything like in the article: https://www.drupal.org/docs/8/theming/adding-stylesheets-css-and-javascr... #Attaching a library to all pages, but my script I do not see it in the source page:

my files:

*.libraries.yml

Hi,

I would like to know of a process or software that can check through my drupal site and through my css file in my bootstrap sub-theme and highlight all the css that is no longer used in the site. I have 4000 lines built up over years and probably half of that is no longer needed.

Hey,

I'm showing a view with exposed filters in a modal dialog. As form actions are placed in the footer by default, the exposed filter submit button appears in the footer. We want it to show the submit button (form actions) above the view content in alignment with the filter input elements.

Anyone know a nice approach to prevent a modal dialog from placing form actions in the modal dialog footer?

Thx
