Theme development

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.

Hello,

I'm using a bootstrap sub-theme to make a webpage.

Which is the right way to declare my bootstrap grid classes(col-xs-* ....)?

Inside the page.tpl.php or to the template.php with the function subtheme_name_preprocess_page().

If the right way is inside the template.php how I can do it?

Thanks!

Thank you for you all for helping me in the past in the forum dedicated to drupal open social.

I've created an aggregated view of a certain content type 'faq'.

Each 'faq' node contains 2 entities - entity_icon and entity_faq.

After overriding the views-view.html.twig I want to print the values of those entities.

All I have is {{ rows }} which represent the list of found nodes.

How do I access the data of these entities inside the rows ?
