I have some question about the theming / html integration into odoo v8. I've been working on Django for some html integration but here I have to do it in Odoo v8.

I have html / statics (css, js, fonts and images) files and I have to integrate them.

But all I've seen so far is to extend existing templates from website addon (website.layout etc).

So I tried first to replace everything in the website.layout from but as I replace a lot of element, I have many errors because some others templates from website can't find some elements by xpath.

But when I extend, it breaks the former html because I have some differences in the html strucure ==> css break.

So, as I come from web framework world (where html integration is basic), I want to know how I can achieve that in Odoo ? What is (are) the best solution(s)? (eg: base.html + block declaration in django).

Thanks you
