Theme development

How do I create a separate menu bar for the logged in user according to their role. I am using drupal 8.

Thanks

Can you help please, I searched for this on google but I can't find a solution, How can I remove the drupal 8 favicon, i tried the theme sitting and global sitting but it's not changing anything because I have to put another link if I want to replace it with my own, But I don't want to replace it I want to remove it.

Thanks

I remember when I think about drupal 8.2.6 or around there, we have zymphonies travel theme for drupal 8 why now their gone, there is only d7 version now?

Hi,
which is the simplest way to add a CSS file and a JS file to all pages of a Drupal7 site?

I've tried with drupal_add_css() in the function: "mytheme_preprocess_html" where mytheme is the active theme, but it doesn' work.
The function in called each time I open a page, but the css isn't loaded.

thank you very much

Hi guys, I'm not sure how I did this...but I did stay out of core (I think)...I've checked all the permissions and it is not a simple matter of my user being anonymous or not.

In my user/registration page I have added some profile fields, and if I access that page with the url (the register link has disappeared for my anonymous browser) I can fill out the information and hit create account.

How can I add some classes to default (or my own created) comments elements so I can target them for adding CSS style.

For example, How can I add some classes or placeholder with using of ThemeName_preprocess_comment to 'subject' and 'name' comments form elements?

How can I target default comments form element?
