XF 2.2 Migrating a existing site style via CSS

[Korsch]

I have a website that I want to mirror my forum from, its extensively html and CSS, how hard is it to have my forum to mirror the appearance of my website. also im guessing its going to be a lot or manual imput of css?

A combination of style property changes, additions to the extra.less template, and template edits if you want to modify the structure/layout.

This is the sites style, mostly HTML and CSS should be simple enough with what is offered with Xenforo. but when I add the CSS to my extra.less how to I then add the value to the site? Will it be a lot of using Xenforo syntax and then classing it with the value I need?
