Module development and code questions

Wow! It has been 12 years I left Drupal.org
Now I'm back. It's all about mobile now. Less about desktop site.

I wonder, is there any module that could take or fetch the LOCATION once the user ENABLE their location in their smartphone (Android/iPhone)?

Hi,

In my site, I have created a custom content type called course and create content with this content type.

Each course is assigned a registration form by using a field with the type of WebForm.

For example, I have created a content "English course", and assign the "English course registration form" in the content.

And I am going to render the whole web form by using the twig template.

If I use {{page.content}}, It would print out the whole content which is not I want.

I used node.field_course_title.value for printing text value,

I have this module that creates a view, with a fulltext search as filter criteria.

My manager and me are working on building a new eCommerce website for the company that we work for.

Hi,

I know that this is probably a dumb question, but... where should I put the code to create a node programmatically?
I've found many snippets to create a node from code, for example: https://gist.github.com/facine/35bb291811c146b6fc9e

But where should I put that code? In a custom module?
In D7 I could create a PHP script, bootstrap Drupal and then just execute the script... what about D8?

Thanks!

Is there a way to change or add class/id tags to items in Drupal? For instance, I want to change a certain set of images but the only class listed on all images is "img-responsive."

I'm very new to Drupal and trying to teach myself everything in a very limited amount of time. So if you answer, please provide clear directions/provide screenshots that a newbie could understand! I really appreciate any guidance or direction to my possible next steps.
