Hi Community,
im new with Odoo and i have some questions about building my own Theme.

Before i build a basic Theme like in the tutorial discribed.

My questions:
1. How can i overwrite the logo-template?
2. How can in overwrite or clear the assets (CSS/less/Js) to set my own css/less/js?
    I dount want just to add some styles.

3. What did i have to do to overwirte existing "snippets" (HTML and options)?
4. Where can i find a list of all existing FE-Templates, which are overwriteable?
5. What did i have to do to set anchor-Links or Links to a lightbox in the main-navigation

In advance i thank you for thinking of my Problems and helping me to understand Odoo a little more.
