Theme development

DRUPAL 8

I installed the bootstrap 3 theme and created the sub-theme.
Before continuing with the installation of the library (bootstrap_library) I have a doubt as to whether or not to install the jquery update module.
I looked around and saw the jquery form page. But the version for drupal 8 is not present.
I argue that there is no need to install it.
Am I wrong?

for the bootstrap menu I read that it can be multilevel. In the management of the blocks I have indicated 3 as a level. I return to the site but it only displays the first level. Is there any other setting to do?

Can someone recommend me a user-friendly theme to manage firmware of specific devices?

For example: adding of components, checking status, server performance statistic, different operations.

Thank you!

Hi,

Does anyone have experience with zetraz theme? I am a beginner. I changed the browser size to small and neither of the menu items show up in small view. Can this be resolved? Would it require lot of work?

After installing the bootstrap theme I return to the site but the display is not responsive. It is not displayed on the whole screen. Which it does when I manage fields or other pages.

Did I do something wrong?
