I'm using the Bootstrap 3.6 theme with Drupal 8.4
I try to center the llogo of my site but I can not do it.
I tested with:
margin: auto;
and
text-align: center;
without success
Here is my site https://www.s1biose.com/
Here is the content of my page.html.twig file on drupal and bootstrap
{# /** * @file * Default theme implementation to display a single page. * * The doctype, html, head and body tags are not in this template. Instead they * can be found in the html.html.twig template in this directory. * * Available variables: * * General utility variables: * - base_path: The base URL path of the Drupal installation. Will usually be * "/" unless you have installed Drupal in a sub-directory. * - is_front: A flag indicating if the current page is the front page. * - logged_in: A flag indicating if the user is registered and signed in. * - is_admin: A flag indicating if the user has permission to access * administration pages. * * Site identity: * - front_page: The URL of the front page. Use this instead of base_path when * linking to the front page. This includes the language domain or prefix. * * Page content (in order of occurrence in the default page.html.twig): * - title_prefix: Additional output populated by modules, intended to be * displayed in front of the main title tag that appears in the template. * - title: The page title, for use in the actual content. * - title_suffix: Additional output populated by modules, intended to be * displayed after the main title tag that appears in the template. * - messages: Status and error messages. Should be displayed prominently. * - tabs: Tabs linking to any sub-pages beneath the current page (e.g., the * view and edit tabs when displaying a node). * - node: Fully loaded node, if there is an automatically-loaded node * associated with the page and the node ID is the second argument in the * page's path (e.g. node/12345 and node/12345/revisions, but not * comment/reply/12345). * * Regions: * - page.header: Items for the header region. * - page.navigation: Items for the navigation region. * - page.navigation_collapsible: Items for the navigation (collapsible) region. * - page.highlighted: Items for the highlighted content region. * - page.help: Dynamic help text, mostly for admin pages. * - page.content: The main content of the current page. * - page.sidebar_first: Items for the first sidebar. * - page.sidebar_second: Items for the second sidebar. * - page.footer: Items for the footer region. * * @ingroup templates * * @see template_preprocess_page() * @see html.html.twig */
