T3 is developed with LESS. When you enable the dev mode, your site loads .less files (templates/your_template/less). The .less files can be compiled to CSS by hitting the "LESS to CSS" button in the top bar of template manager. Your site will load .css files when DEV MODE is turned off. Please note that it not compile one by one file, when compile, there are some .less files are joined for better performance, that's why you don't see some missing css files for LESS.

All less files of template are located in "templates/your_template/less". You can customize style of your template with the .less files, after customizing, please compile LESS to CSS and turn dev mode off for better performance.

When you enable the dev mode, your site loads .less files

Yes, but it loads the folder t3-assets! here is where you can modify the code does not show..

For example I want to change backround-color ...:
}
.navbar-default
background-color: #f8f8f8; :This is css file.This code is registered in the template.css :897.I after go to the less folder.open to template.less
border-color: #e7e7e7; bud this its different code! this code(.navbar-default) is not!
}

..for black. .

Please tell me how to write? And what less folders??

No, when you enable dev mode, it loads .less files in the folder: templates/ja_template/less. But when you debug, you may see the path to the file like:

t3-assets.dev.templates.t3_bs3_blank.layouts.template.less.css:16

You can ignore the

t3-assets.dev

, the real file to customize style is:

 templates.t3_bs3_blank.layouts.template.less

Please check attached image for more detail.
