Theme development

Hello friends,

I asked a similar question to these under the Module Development and Code questions, but I think this question may actually be better suited under this topic.

I am working on a drupal website that has a theme installed to it.

I would like to set the Front/Home page of the website to a .html.twig template I have in a custom module I am busy working on.

How would I go about doing this? I have done some googling and it likes like the answer lies somewhere with page--front.html.twig, but I am not sure where to go from here.

I've got a field collection for slides in a paragraph. Each field collection slide has a background image field and a headline field. The editor can add as many slides as they want. I'm trying to theme this output. So, I've been assuming I should loop through the field collection items and spit each out, but it's completely baffling me. I'm not the best PHP'er, but I get by.

In 'paragraphs-item--content-slider.tpl.php' this prints the first 2 just fine, as you would expect:

I have a site with the Bootstrap 3.3.7 theme and I want the farm navigation menu to click when I click outside.

I managed to make it work with the following code :

    (function ($) {
      'use strict';
    
      $(document).click(function (event) {
           $('.navbar-collapse-first').collapse('hide');
      });
    
    }(jQuery));

My problem :

When I click next to a link in the navigation menu, it closes. I want it to close only when I click OUTSIDE of the menu.

Hi, this may be a naive question as I'm a real beginner to web development. I built a blog website using Drupal 8, and downloaded and installed a theme. I would like to modify the theme, as I want to make the site title smaller and the navigation menu bigger. I first used the browser's inspect element tool to modify the CSS, which did exactly what I wanted. However, when I attempted to modify the style.css file and upload the modified version to the server, my changes did not take effect.

I have ten custom List (integer) Fields, each has 5 values to choose from on the list. Within my Twig configuration I've been programmatically using {% if node.field_options.value == 'X' %} to display some CSS and an Image based on value returned.

Performance wise, is there anything wrong with doing this or will it slow down rendering of the page?

I have a strange problem with a .theme file on a Drupal 8 (8.5.4) site

Drupal are not registrating any changes that I make to the file.
Right now the file is empty but all the old functions still active on the site.

Drupal only registrate if I rename or delete the .theme file.

I have cleared the cache with Drush cr and from the GUI, but stil no effect.

I have delete the whole theme folder at reinstalled it, but no effect.

The site is running on a nginx/1.10.3 server and using Redis Cache.

I have no knowlegs of Redis.
