Hi Jack

Please list all your concern and I am willing to explain one by one for you. For your questions in the above thread, please check the following suggestions:

1. I would like to navigate menus and LOGO on the line, how should I modify it?
A: You can edit it in the header.php and mainnav.php file in the "templates/t3_bs3_blank/tpls/blocks/" folder but it requires you some technical skill. If you want to implement this in your site, you can pm me your site url, admin account and ftp info, I could help you.

2. If i turn on the development model, where to modify LESS file is to specify the t3-assets / dev folder modifications, or to the template / less modified?
A: Just ignore the "t3-assets/dev" as its just cache folder, please check the image: http://easycaptures.com/fs/uploaded/760/2680714599.jpg

3. If I already have a front-end HTML code, how to show it with t3 framework?
Basically, you can display the HTML in module or in article. In this case, you can create new module/article, paste the HTML and save it (remember to disable editor) and assign it to the page you want.

P/S: please check our detail documentation at: http://www.t3-framework.org/documentation.html

Regards.
