Theme development

Hey guys, I am new to drupal, here I have a problem.
I know html+css, and can make a simple website with html/css, or some framework like bootstrap. But not familar with php or other language.

Now I want to study drupal, since d8 is the newest version, I decided to start with d8. But I am confused when I reading the document, I had read theme guide in https://www.drupal.org/documentation/theme, but still don't know how to create a custom theme(which I had already done in html+css).

Sorry I placed this in the wrong queue. Moving to bootstrap theme queue....https://www.drupal.org/node/2662924

I'm using Drupal Bootstrap 8x 3.0 beta2 with a sub theme. Whenever I attempt to add new content with the "save and keep published" button, instead of saving the data, it's reverting to the preview page and won't save.

Hi,
I set in site information title and slogan. Lated I have edited file html.html.twig to put site slogan in the title tag but with no success.

    <title>{{ head_title.name}}</title>

when i add
<title>{{ head_title.name, head_title.sloagn}}</title>
then tamplate is crashed. Even if i dump(head_tittle) there is no slogan.

Included at theme foundation zurb dropdown main-menu?

Hi guys,

For a page that contains a webform, I just want to render the barebones webform contents, with none of the surrounding default bartik theme.

I‘ve created a page--node--4.tpl.php file, and that works fine. But I don‘t know what to put in there to make it draw the webforms‘ contents.

I also (don‘t judge me!) need to remove the "powered by drupal" link.

All help appreciated!

Hey y'all - I'm new to Drupal, coming from WordPress.

I know this is probably ridiculously simple, and there are articles all over the 'net about template naming conventions in Drupal 8, but it's just not making sense. I created a custom content type called 'Staff Member' (machine name 'staff'); there will be many staff members. I'd like to use a custom template to display single staff member records, so I created a 'node--staff.html.twig' file in the /templates/ subdirectory of my custom theme directory. I've also tried it directly in the custom theme directory.
