Comment créer des liens d'ancrage ?

To insert an anchor link pointing to a certain block (section) within a page, add a special block to the place you need — anchor ("Other" category → T173 Anchor link in the Block library). In the Content of this block, specify the anchor title, such as "contacts". You can now link to it in any block by specifying a link that looks like #contacts. When the visitor clicks the link, they jump to the anchor.

To ensure that anchor links work everywhere, use links that look like /#anchor (for anchor links on the Home page) and /page#anchor (for anchor links on other pages).

Pour un effet de défilement fluide, ajoutez le bloc T178 de la catégorie "Autres". Vous n'avez pas besoin de modifier les paramètres. N'ajoutez qu'un seul bloc T178 par page. Cela permettra d'assurer des transitions fluides entre les liens internes.
